3 Working with Oracle JDeveloper

This chapter is designed to get you up and running quickly on Oracle JDeveloper. Find information about working with the general development environment, source files, connections, using the online help, and common development tools.

This chapter includes the following sections:

3.1 About Working with Oracle JDeveloper

JDeveloper is the main development platform for the Oracle Fusion Middleware suite of products. It is a cross-platform IDE that runs on Windows, Linux, Mac OS X, and other UNIX-based systems.

3.2 Working with JDeveloper Roles

Roles enable you to tailor the JDeveloper environment. The modified environment removes items that you do not need from JDeveloper, including menus, preferences, New Gallery, and even individual fields on dialogs. The role you select determines which features and options are available to you as you work in JDeveloper.

The roles available are:

  • Default Role. This role allows you to access all JDeveloper features. The other roles provide subsets of these features.

  • Customization JDeveloper. This role allows you to create customizable applications, using the Oracle Metadata Services (MDS) framework.

  • Database Edition. This gives you access to just the core database development tools.

  • Java EE Edition. This includes only features for core Java EE development.

  • Java Edition. This includes only features for core Java development.

Note:

The full set of online help is always available regardless of the role you have chosen for JDeveloper.

3.2.1 How to Change the JDeveloper Role

JDeveloper prompts you to select a role the first time it is run. You can also change the role while JDeveloper is running.

To change the JDeveloper role:

  1. From the main menu, select Tools > Switch Roles.

  2. The current role contains a bullet next to it. In the Switch Roles menu, select the role you want to switch to.

3.3 How to Manage JDeveloper Features

To optimize performance and user experience, JDeveloper allows you to just load the features you need for your project. Managing features enables you to see only those components of the IDE that are most relevant to your work. Managing features has no affect on the data in a project itself.

For example, assume two projects used to create two different views into an application. The first project might have Java features loaded, which informs JDeveloper that the IDE should reflect the Java technology stack. Such filtering eliminates clutter from individual projects. The second project might have a features loaded for Swing/AWT, informing JDeveloper to reflect IDE components required for Swing/AWT development.

To add or remove features in JDeveloper:

  1. From the main menu, select Tools > Features. The Manage Features for role dialog opens. This dialog displays the features available in the current JDeveloper role. These features are checked by default.

  2. Search for the feature you want to add or remove by entering it in the Search field, or scroll in the list of Available Features. Click a feature or feature category and view its description on the right.

  3. Check the features you want to add, and uncheck the features you want to remove. Click the Check for Updates icon to open the Check For Updates wizard which allows you to load features from an extension.

  4. Optionally, to clear previously loaded features from the cache, click Clear Feature Loading Cache.

  5. Click OK when you are done.

3.4 Working With Windows In the IDE

JDeveloper allows you to arrange the windows according to your convenience. JDeveloper uses two kinds of windows in the IDE:

  • Dockable windows that can be placed anywhere in the IDE.

  • Tabbed editor windows that are fixed in the center of the IDE.

3.4.1 How to Maximize Windows

Double-click the title bar of any JDeveloper window to quickly maximize to full screen view. Double-click the title bar again to return the window to its former position in the IDE.

3.4.2 How to Minimize and Restore Dockable Windows in the IDE

You can minimize any dockable window in JDeveloper, or set it to remain open in place. The default state is set to remain open.

When a window is set to stay open, its position is static. It remains always visible, in whichever position you have docked it.

When a window is set to minimize, its behavior is more fluid. When you give it focus, it opens fully in the general area (top, bottom, left, right) where you last left it docked. When you move the focus elsewhere, the minimized window collapses into the margin. Whether open or closed, any minimized window's status set to minimize is identified by a named button in the margin.

To minimize any dockable window:

  • Click the Minimize icon in the far right-hand corner of the window set to be kept open.

    If the window currently has focus, it now expands to full height and remains in place. If the window does not have focus, it collapses into the margin.

    When you minimize a window, a button bearing that window's name appears in the margin. You can toggle the minimized window open and closed with this button.

    Note:

    When you minimize a window that exists in a docking zone that also contains other windows, all windows in the docking zone are minimized.

3.4.3 How to Dock Windows in the IDE

All of the tools available under the View menu—the Application Navigator, Structure window, Property Inspector, and so on—can be arranged however you like. You can dock them singly or in groups. You can also tab windows together in one location, either as docked or floating windows.

The following table provides information on how to move dockable windows.

Requirement Action
Move a solitary docked window Grab its title bar and drag
Decouple a docked window from a group Grab its title bar and drag
Move a group of docked, tabbed, or docked and tabbed windows Grab the title bar for the group—the topmost horizontal title bar, empty but for the close box—and drag.
To decouple one tabbed window from a group Grab the window's tab and drag.

Note:

The title bars for docked windows sometimes appear vertically, on the side of the window.

The following table provides information on ways to reposition dock windows:

Requirement Action
Dock a window (or window group) against another edge of the development area Drag the window (or window group) to the destination edge
Dock a window (or window group) alongside another window Drag the window (or window group) to the top, bottom, or side edge of the docked window
Tab one window with another Drag the window to be tabbed into the center of the destination window (or window group) and release

3.4.4 About Dockable Windows in the IDE

You can float any window that's normally docked—the Application Navigator, any custom navigator, the Log window, the Property Inspector, the Component Palette. You can also resize and position it wherever you would like within JDeveloper.

Generally, floating windows are best suited for a large screen with enough room for displaying both the information windows and your source code. If you are using floating palettes on a smaller screen they can sometimes be hidden by other information windows as you work.

3.4.5 How to Close and Reopen Dockable Windows in the IDE

You can easily open and close the main elements of the JDeveloper IDE, which include the navigators, Structure window, Property Inspector, Component Palette, Resource Palette and Log window.

To open a closed window:

  • In the View menu, choose the name of the window.

You can close an open window in one of these ways:

  • Click the Close icon which appears on the tab window's name.

  • With the focus in the window, press Shift+Escape or Ctrl+Click.

3.4.6 How to Restore Window Layout to Factory Settings

To restore the layout of dockable windows in JDeveloper, go to the Window menu and select Reset Layout to Factory Settings.

3.5 Navigating The IDE

You can accomplish any task in JDeveloper using the keyboard as you use the mouse.

3.5.1 How to Work With Shortcut Keys In The IDE

JDeveloper comes with several predefined keyboard schemes. You can choose to use one of these, or customize an existing set to suit your own coding style by changing which keyboard shortcuts map to which actions.

To load preset keyboard schemes:

  1. From the main menu, choose Tools > Preferences.

  2. In the preferences dialog, select the Shortcut Keys node. For more information at any time, press F1 or click Help from within the Preferences dialog.

  3. On the shortcut keys page, click More Actions and then select Load Keyboard Scheme. The Load Keyboard Scheme dialog appears, with the currently loaded keyboard scheme highlighted.

  4. In the Load Keyboard Scheme dialog, select the scheme you wish to load and click Ok.

  5. On the Shortcut Keys page, if you have finished, click Ok.

To view JDeveloper commands and their associated keyboard shortcuts (if assigned):

  1. From the main menu, choose Tools > Preferences.

  2. In the Preferences dialog, select the Shortcut Keys node.

  3. On the Shortcut Keys page, under Available Commands, you can view the complete set of JDeveloper commands, and what keyboards shortcuts (if any) are assigned to each. If you are looking for a particular command or shortcut, or want to look at shortcuts for a particular category of commands only, enter a filtering expression in the Search field.

  4. You can also define new shortcuts, or change existing ones.

To define a new keyboard shortcut for a command within a given keyboard scheme:

  1. From the main menu, choose Tools > Preferences.

  2. In the Preferences dialog, select the Shortcut Keys node. For more information at any time, press F1 or click Help from within the preferences dialog.

  3. On the Shortcut Keys page, under Available Commands, select the command that you wish to define a new shortcut for.

  4. To define a new shortcut for this action, place focus on the New Shortcut field, and then press the key combination on the keyboard.

    If this proposed shortcut already has a command associated with it, that command will now appear in the Conflicts field. Any conflicting shortcuts are overwritten when a new shortcut is assigned.

  5. To assign this shortcut to the action selected, click Assign. If you want to delete an already-assigned shortcut, click the Delete button in the toolbar.

    If you want to assign more than one shortcut to a command, select the command and click the Duplicate button. Then, type the shortcut key in the New Shortcut field and click Assign.

  6. When you are finished, click Ok.

To import or export keyboard schemes:

  1. From the main menu, select Tools > Preferences to open the Preferences dialog.

  2. Click More Actions > Export or Import. Keyboard schemes are stored as XML files.

3.5.2 Keyboard Navigation In JDeveloper

For any action that can be accomplished with a mouse, including selection, there is a way to accomplish the action solely from the keyboard. You can accomplish any task in JDeveloper using the keyboard as you can using the mouse.

The shortcut keys defined in the Java Look and Feel guidelines provide the base set for JDeveloper. The various predefined keyboard schemes available in JDeveloper are then overlaid upon this base set. If the same shortcut key exists in both the look and feel guidelines and the JDeveloper keyboard scheme, the JDeveloper scheme prevails. If a shortcut key defined by the look and feel guidelines does not appear in a JDeveloper scheme, then it is the original look and feel definition that remains in effect when the scheme in question is enabled.

At any given time, then, the shortcut keys enabled in JDeveloper depend upon the interaction of the currently enabled scheme with the Java look and feel guidelines. When you first open JDeveloper, the default scheme is enabled. You can change this scheme whenever you wish, and within each scheme, you can customize any of the shortcut key assignments that you would like. Note that any customized shortcuts you create in a scheme are not retained when another predefined keyboard scheme is activated (or even if the same scheme is reloaded).

To load predefined keyboard schemes, view current shortcut assignments within a scheme, and customize those assignments, you will need to open the preferences dialog. To open the dialog, choose Tools > Preferences (or on the keyboard, press Alt+T+P) from the main menu and then, using the arrow keys in the left-hand pane, navigate to the Shortcut Keys node. For details on working with the dialog, with the page displayed, click Help (or on the keyboard press H).

3.7 Working with the Resource Palette

When designing and building applications, you may need to find and use many software assets. You may know what you want to find, but you may not certain where to find it or even what the artifact of interest is called. Even if you think you know where to find the artifact, and what it is called, you might not know how to establish a connection to the source repository. Consider the following:

  • An application developer needs to find and incorporate shared model, view and controller objects created by other members of her team, and by other product teams.

  • A UI designer needs access to a corporate catalog of images, style sheets, templates and sample designs to facilitate rapid creation of standards-compliant pages.

  • An application integrator needs easy access to a variety of web services of interest to a particular domain.

  • An end user needs to find relevant content (for example, portlets and UI components) for use while personalizing a page. In each of these cases, the user has a simple goal: find the resource(s) needed for the task at hand. The process of discovering and accessing the assets should be as effortless as possible.

The Resource Palette in JDeveloper addresses this. It lets you:

  • Locate resources stored in a wide variety of underlying repositories through IDE connections

  • Locate resources by browsing a hierarchical structure in catalogs

  • Search for resources and save searches

  • Filter resources to reduce the visible set when browsing

  • Use a resource you have found in an application you are building

  • Facilitate resource discovery and reuse by sharing catalog definitions

3.7.1 How to Open the Resource Palette

The resource palette allows you to create connections to a number of different resources, such as application servers, databases, WebDAV servers, from where you can use them in different applications and share them with other users.

To open the Resource Palette:

In the main menu, choose View > Resource Palette.

By default, the Resource Palette is displayed to the right of the JDeveloper window.

3.7.2 How to Work With IDE Connections

The connections defined in the Resource Palette are listed in the IDE Connections panel of the Resource Palette.

When you create a connection in JDeveloper, you can create it in the context of the Resource Palette as an IDE connection that can be reused in different applications, or shared between users, or as application connections.

Some types of connections may appear in special connection-type navigators. For example, database connections display in the Database Navigator under the IDE Connection node (for IDE connections), or the application-name node (for application resource connections). The Database Navigator is where you edit objects through the database connection.

The different types of connection that can be made depends on the technologies and extensions available to you. To see what you can create a connection to, choose New Connection from the New button in the Resource Palette.

3.7.2.1 Resource Palette Connection Descriptor Properties Location

The file system location for the Resource Palette connection descriptor definition information is

system-dir/jdeveloper/system11.1.2.n.nn.nn.nn/o.jdeveloper.rescat2.model/connections/connections.xml

3.7.2.2 Defining the Scope of a Connection

In JDeveloper 11g you have two ways of creating and managing connections. You can define a connection to be used in the context of an application (called an Application Resource connection), or for the IDE as a whole (called an IDE connection). You use the same dialog to define both of these, but their scope within JDeveloper is different.

When you first create a connection you choose the connection scope. You cannot subsequently change the connection scope.

3.7.2.2.1 Application Resource Connections

These connections are locally scoped and just available within the application. Connections in application resources are artifacts of the application and are deployed within the application. These types of connection are listed in the Application Resources panel of the Application Navigator, under the Connections node.

The file system location for the connection descriptor definition information is application-folder/.adf/META-INF/connections.xml, where application-folder is the path for the selected application.

3.7.2.2.2 IDE Connections

These are globally defined connections available for reuse, and they are listed in the IDE Connections panel of the Resource Palette. You can copy IDE connections to the application navigator to use them within an application.

3.7.2.3 How to Create IDE Connections

You can create connections in the Resource Palette to resources available to JDeveloper.

The specific types of connections you can make depend on the technologies and extensions available to you.

To create an IDE connection:

  1. In the Resource Palette IDE Connections panel, choose New Connection from the New button.

  2. Choose the type of connection you want to create, and enter the appropriate information in the Create Connection dialog. For more information at any time, press F1 or click Help from within the dialog.

3.7.2.4 How to Edit IDE Connections

Once you have created a connection in the Resource Palette, you can edit details of the connection, but you cannot change the connection name.

To edit an IDE connection:

  1. In the Resource Palette IDE Connections panel, choose Properties from the context menu of a connection.

  2. The Edit connection dialog opens where you can change the connection details. For more information at any time, press F1 or click Help from within the Edit connection dialog.

3.7.2.5 How to Add IDE Connections to Applications

You can use connections in the Resource Palette in an application.

The connection can be added to the application currently open in JDeveloper, and it is listed in the Application Resources panel of the Application Navigator, under the Connections node.

To add a connection to an application:

In the Resource Palette IDE Connections panel, choose Add to Application from the context menu of a connection.

Alternatively, drag the resource from the Resource Palette and drop it onto an application page.

Alternatively, drag the connection from IDE Connections in the Resource Palette and drop it onto the Application Resources pane in the Application Navigator.

3.7.3 How to Search the Resource Palette

There are two ways of searching in the Resource Palette:

  • Performing a simple search

  • Performing an advanced search, where you enter parameters in a dialog

In addition, you can define a dynamic folder in a catalog where the content of the folder is defined by a query expression that is executed when the folder is opened.

The time the search takes depends on how many resources there are in the Resource Palette, and how long it takes to connect to them, and the results are displayed in the Search Results panel.

You can stop a search before it has completed by clicking the Stop Search button.

3.7.3.1 Performing a simple search

In this case, the search is performed across all the contents of the Resource Palette, and it may take some time because JDeveloper connects to remote resources during the search.

To perform a simple search:

  1. In the Resource Palette, click the Search Options button to choose whether the search is performed against the Name, Type or Description of the resource. For more information at any time, press F1 or click Help from within the Resource Palette.

  2. Enter a search string in the field. For example, if you want to find every resource that contains dep in the name, choose Name in step 1, and enter dep. Every resource that contains the string dep will be listed in the search results.

  3. Click the Start Search button to start the search.

3.7.3.2 Performing an advanced search

You can specify a series of search criteria, and you can choose where to start the search from.

To perform an advanced search:

  1. In the Resource Palette, choose Advanced Search from the context menu of an object in the My Catalogs panel or the IDE Connections panel. For more information at any time, press F1 or click Help from within the Advanced Search dialog.

  2. Define where the search starts. Either select from Search in, or click Show Hierarchy which allows you choose within a hierarchical list of the Resource Palette contents.

  3. Enter search criteria to return the resources you want, and click Search.

3.7.4 How to Reuse Resource Palette Searches

You can save a search and reuse it. There are two ways of saving a search in order to reuse it:

  • As a dynamic folder, where the contents of the folder are created dynamically based on the search criteria when the folder is opened.

  • As a static folder containing the results of the search.

Dynamic folders can also be created directly in a catalog.

To save a search:

  1. In the Resource Palette Search Results panel, choose Save Search from the context menu.

  2. In the Save Search dialog, choose:

    • Save Search Criteria, to create a dynamic folder.

    • Save Search Results, to create a static folder of results.

    For more information at any time, press F1 or click Help from within the Resource Palette.

  3. Enter a name for the folder.

  4. Choose the catalog to contain the folder, either from the dropdown list, or from the hierarchical list displayed when you click Show Hierarchy.

3.7.5 How to Filter Resource Palette Contents

Filters allow you fine-tune the contents of catalog folders.

To filter the contents of My Catalogs:

  1. In the Resource Palette, choose Filter from the context menu of an object in the My Catalogs panel or the IDE Connections panel. For more information at any time, press F1 or click Help from within the Filter dialog.

  2. Enter a string to define the filtering. Only entries in the folder that contain the string will be shown.

3.7.6 How to Import and Export Catalogs and Connections

Catalogs and connections are shared by importing Resource Catalog archive (.rcx) files that have been exported by another user.

To export a catalog:

Note:

When you select a catalog to export, any connections in the catalog are also selected. If you deselect the catalog before exporting, you must be sure to also deselect the connections that are not wanted in the archive file.
  1. In the Resource Palette, choose Export from the context menu of an object in the My Catalogs panel or the IDE Connections panel.

  2. In the Export Catalog and Connections dialog, select the catalogs and connections to be exported, and decide how errors will be handled. For more information at any time, press F1 or click Help from within the Export Catalog and Connections dialog.

To import a catalog:

  1. In the Resource Palette, choose Import from (New).

  2. In the Import Catalog and Connections dialog, specify or browse to the path and name of the Resource Catalog archive file (.rcx). For more information at any time, press F1 or click Help from within the Import Catalog and Connections dialog.

  3. Choose the catalogs and connections you want to import, and determine how to handle errors.

3.7.7 How to Refresh the Resource Palette

You can refresh the contents of the Resource Palette.

To refresh the Resource Palette:

  1. In the Resource Palette, choose Refresh from the context menu of an object in the My Catalogs panel or the IDE Connections panel.

3.7.8 How to Work With Resource Palette Catalogs

A catalog is a user-defined construct for organizing resources from multiple underlying repositories. The contents of a catalog and its associated folder structure can be designed to be used by an individual developer, or they can be targeted towards specific groups of users such as the UI designers for a development project.

Catalog folders organize resources in a catalog. You use catalog folders in the same way you would to organize files in a file system or bookmarks in a Web browser. Each catalog folder can contain any combination of:

  • Folders.

  • Dynamic folders, which are populated using a query.

  • Filters, which are used to fine-tune the content of a folder or subtree.

3.7.8.1 How to Create Catalogs

You can organize the information in the resource palette in catalogs.

To create a catalog:

  1. In the Resource Palette, choose New Catalog from the New button.

  2. In the Create Catalog dialog, specify a name for the catalog. For more information at any time, press F1 or click Help from within the Create Catalog dialog.

  3. (Optional) Provide a description for the catalog, and the email of the catalog administrator.

3.7.8.2 How to Rename Catalogs

You can rename catalogs.

To rename a catalog:

  1. In the Resource Palette, right-click the catalog, and choose Rename from the context menu.

  2. In the Rename dialog, specify a new name for the catalog. For more information at any time, press F1 or click Help from within the Rename dialog.

3.7.9 How to Work with Catalog Folders

Dynamic Folders provide a powerful way to dynamically populate a catalog folder with resources. The content of the folder is defined by a query expression that is executed when the folder is opened. The results of the query appear as the contents of the folder.

To create a dynamic folder:

  1. In the Resource Palette, choose New Dynamic Folder from the context menu of a catalog in the My Catalogs panel or the IDE Connections panel. For more information at any time, press F1 or click Help from within the Create Dynamic Folder dialog.

  2. Define the search criteria that will be used to populate this folder when it is opened.

3.7.9.3 How to Add Resources to a Catalog

You can add a connection from the IDE Connections panel or a resource from the Search panel in the Resource Palette to a catalog in My Catalogs.

To add a resource to a catalog:

  1. In the Resource Palette, right click a connection in the IDE Connections panel, or the result of a search in the Search panel and choose Add to Catalog from the context menu.

  2. The Add to Catalog dialog opens for you to specify the name for the resource in the catalog, and the catalog to add it to. For more information at any time, press F1 or click Help from within the Create Connection dialog.

Alternatively, you can drag an item from under IDE Connections and drop it on a catalog or catalog folder.

You can reorganize a catalog by selecting an item or folder in the catalog and dragging it to another folder in the same catalog, or to another catalog.

3.8 Working with Source Files

JDeveloper includes an editor for editing source files across several technologies, including Java and XML, among others.

3.8.1 Using the Source Editor

JDeveloper includes an editor for editing source files across several technologies, including Java and XML, among others.

Depending on the type of source file you are editing, the source editor will be available in one of the following forms:

  • Java Source Editor

  • XML Editor

  • HTML/JSP Source Editor

  • JavaScript Editor

In addition to technology-specific features, the source editor also has a set of common features across all technologies that enhance the coding experience. These features include bookmarking, code insight, code templates, and several other features that enable you to code faster and better.

Use the Code Editor page in the Preferences dialog to customize the source editor to suit your coding style.

The source editor offers a set of common features across all technologies that provide intuitive support for a variety of coding tasks. Available across all forms of the editor, these features enhance your coding experience through quicker execution of coding tasks and better navigation through code.

Breadcrumb Navigation

The breadcrumb bar, located at the bottom of the editor window, shows the hierarchy of code entities from the current caret position up to the top of the file. Hovering the mouse cursor over a node pops up some information about the node, and clicking on the node navigates the caret to the node location.

A breadcrumb can be clicked to display a popup list of child breadcrumbs can be displayed (where appropriate). For example, for a Java class, you can click the breadcrumb to display the class' methods and inner classes in a list. Choosing an item on this list will navigate the editor to its location.

If block coloring has been activated and colors have been assigned, breadcrumbs are highlighted in the same color as their corresponding code blocks.

Overview Popup

The right margin of the editor provides colored overview marks that are indicators for a location in the source file. Hovering the mouse over an overview mark makes a popup appear which displays information about the item in that location of the source file, and a snippet of the relevant code.

The following overview indicators are provided:

  • A square mark at the top right corner of the editor window indicates the overall health of your source file, as per its color. White indicated that the health is currently being calculated. Green indicates that there are no errors or warnings in the file. Red indicates errors, and yellow indicates warnings

  • Rectangles, depending on their color, signify the occurrence of the following source editing artifacts:

    • Red: Java code error

    • Pale blue: bookmark

    • Medium blue: current execution breakpoint

    • Yellow: occurrence of searched text

    • Pale orange: Java warning

    • Bright orange: Profile Point

You can also press Ctrl anywhere in the right margin to view a popup window that displays a portion of the source code that is not currently in view. By adjusting the position of the mouse while pressing Ctrl, you can view the entire code without scrolling in the editor itself

Hovers

Hovers enable you to position the mouse cursor over certain areas of the IDE and get some information on them in a popup window that appears floating in front.

Whitespace Display

Tools menu > Preferences > Code Editor > Display > Show Whitespace Characters

This feature optionally renders spaces, new lines, carriage returns, non-breaking spaces, and tab characters as visible characters in the editor. Turned off by default, this can be enabled and disabled using the Preferences Dialog.

Duplicate Selection

Edit menu > Duplicate Selection

Duplicates the currently selected block of code, and places the copied code beside the original code. After duplication, the newly inserted code is selected. The clipboard is not affected by this operation.

Vertical Selection

Edit menu > Wrap Selection

This feature enables you to select code vertically. when you do not want to select text that wraps around the end of lines. This is useful for selecting tabular data, or vertically aligned code blocks.

Join Lines

Join the current line to the next, or join all lines in a selection. Any comment delimiters or extra whitespace are intelligently removed to join the lines.

Default keyboard shortcut: Ctrl+J

Cursor Position

When the source editor is in use, the status bar at the bottom displays the line and column coordinates of the current position of the cursor.

Mouse Wheel Zoom

Hold down the Ctrl key and use the mouse scroller to zoom in to or zoom out of the code editor.

3.8.1.1 Features Available From the Context Menu

The generic source editor also provides a set of features through the context menu. To use these features, in the context menu, select Source. Depending on the type of source file in use, items other than the ones mentioned below may be present in the context menu. For example, the Java Source Editor contributes Java-specific options to the source editor context menu.

Note:

These features are also available through the Source menu.

Completion Insight

Completion insight provides you with a list of possible completions, such as method names, and parameter types if they are applicable, at the insertion point, which you may use to auto-complete Java code you are editing. This list is generated based on the code context found at the insertion point. The contexts supported by completion insight are:

  • Within package and import statements

  • Within extends, implements, and throws clauses

  • Within continue and break statements

  • Within general code expressions

Default keyboard shortcut: Ctrl+Space

Parameter Insight

Parameter insight provides you with the types and names of the parameters of the method call you are typing. If the method is overloaded, multiple sets of parameter types and names are listed.

Default keyboard shortcut: Ctrl+Shift+Space

Note:

If errors for the file appear in the Structure window, Code (Completion or Parameter) Insight may not work. If the class(es) you are using are not in your project (that is, not on your classpath), Code Insight will not appear. Please note that you may need to compile your src files in order for Code Insight to have access to them.

Complete Statement

Use to auto-complete code statements where such a completion is obvious to JDeveloper; for example, semi-colon insertions at the end of a statement.

Default keyboard shortcut: Ctrl+Shift+Enter

Expand Template

Insert a code template from a list of JDeveloper's predefined code templates. The code templates offered are context sensitive. For example, templates to declare class variables are only offered when the cursor is in the appropriate place in the class file.

Default keyboard shortcut: Ctrl+Enter

Code Assist

Code Assist examines your code in the editor and provides assistance to fix common problems. A Code Assist icon appears in the editor margin when JDeveloper has a suggestion for a code change. To invoke Code Assist manually, press Ctrl+Alt+Enter. To select an action listed in Code Assist, press Alt+ the underlined key.

Default keyboard shortcut: Ctrl+Alt+Enter

3.8.4 How to Manage Source Files in the Editor Window

Oracle JDeveloper possesses several capabilities for easier handling of files in the editor window.

3.8.4.1 Maximizing the View of a File

You can open a file to fill the maximum view available in JDeveloper. This is done by maximizing the source editor to fill JDeveloper

The same technique of double-clicking a tab can be used for any of the other windows in JDeveloper, for example, the Help Center, or the Application Navigator.

To maximize the view of a file:

  • In the source editor, double-click the tab of the file. The source editor becomes the only window visible in JDeveloper, with the file you have chosen currently displayed in it.

To reduce the view of a file to its former size

  • Double-click the tab of the file again. The windows within Oracle JDeveloper return to their former layout.

3.8.4.2 Navigating Between Open Files in the Editor Window

You can navigate through files visually (cycling through by tab), historically (cycling through by order of access), or numerically (cycling through based on file shortcut key assignment).

To navigate through open files by tab:

  • Press Alt+Left Arrow or Alt+Right Arrow. Use Alt+Left Arrow to navigate to the left, and Alt+Right Arrow to navigate to the right.

To navigate through open files based on history:

  • Press Ctrl+Tab or Ctrl+Shift+Tab

    Use Ctrl+Tab to open the last active file. Note that opening a file renders it the currently active file, such that the previously active file now becomes the last file to have been active.

    For example, given files A, B, and C (opened in the order C, B, A), where file A currently has focus, pressing Ctrl+Tab brings B to the foreground. Now B is the file with focus and A is the last active file. Pressing Ctrl+Tab again thus brings A back to the foreground.

  • Press Ctrl+Tab+Tab+Tab to cycle through files by order of access without stopping. Only when you stop on a file is that file given focus. Stopping on a file is equivalent to using Ctrl+Tab on that file.

3.8.4.3 How to Display the List of All Currently Open Files

You can display all the files currently open in the editor window, or all the files currently open in a particular tab group.

To display the alphabetical list of all the files currently open in a given tab group:

Click the File List button in the upper right-hand corner of the editor window. Alternately, with the focus in the editor window, press (in the default keyboard scheme) Alt+0.

If the editor window is not subdivided, the list will contain all open files. If the editor window is subdivided, the list will contain all the open files in that tab group.

To display the alphabetical list of all the files currently open in the editor window, regardless of split or detached files:

  • From the main menu, choose Window > Windows.

3.8.4.4 How to Access a Recently Opened File

Oracle JDeveloper remembers the last files you have edited.

To access a recently-edited file, irrespective of whether it is currently open or not:

  1. From the main menu, choose Navigate > Go to Recent Files or (in the default keyboard scheme) press Ctrl+ =.

  2. In the Recent Files dialog, select the file from the list or begin typing the first letters of the filename.

  3. Click OK.

By default, only those files opened directly (through the navigator, for instance) appear in the list. Those opened indirectly (for example, as you debug code) do not automatically appear. To view files opened both directly and indirectly, select Show All.

3.8.4.5 How to Open Multiple Editors for a File

You can split the editor window horizontally or vertically, opening a single file in multiple views. In each view, you've the choice of changing which editor the file is opened in.

You can split a file into as many views as you like. The split views are automatically synchronized with each other.

To open a single file in multiple views:

  1. From the main menu, choose Window > Split Document.

    The editor window is now split in two, with two identical and independent windows opened on the same file. Each window has its own set of editor tabs at the bottom.

  2. In each window, select the editor tab to view the file in that editor.

    Note that some editors (such as the Java Visual Editor) permit only one view at a time on a file.

Alternately, you can split the file using the mouse, either horizontally or vertically.

To split the file horizontally, grab the splitter just above the vertical scroll bar (on the upper right-hand side of the window) and drag it downward.

To split the file vertically, grab the splitter just to the right of the horizontal scroll bar (on the lower right-hand side of the window) and drag it left.

To navigate quickly between split views:

  • Press F6 to cycle forward.

  • Press Shift+F6 to cycle backward.

To collapse those multiple views back into one:

  • From the main menu, choose Window > Unsplit Document.

Alternately, you can drag the splitter past the end of the editor window.

3.8.4.6 Viewing More Than One File at a Time

You can split the editor window horizontally or vertically, opening views on more than one file at a time. Each view is independent of the others

You can split the editor window into as many different independent views as you would like.

To view more than one file at a time, in independent windows:

  • From the main menu, choose Window > New Tab Group.

    The editor window is now split in two, with different files in each window. Each window has a set of document tabs at the top and a set of editor tabs at the bottom. Each window is known as a tab group.

    You can create as many tab groups as you like.

Alternately, you can detach a file using the mouse, by grabbing the document tab for the file and dragging it towards the area of the window where you want the file displayed.

As you drag the tab, the icon that follows the cursor changes. A split window with an arrow to the left, right, top, or bottom indicates that if you release the mouse now, the new window will be placed in that relationship to the current window.

To move a file to a different tab group:

  1. Drag the document tab for the file to the center of the area occupied by the tab group you wish to attach it to.

  2. When the icon that follows the cursor changes to show a miniature window with tabs, release the mouse.

To collapse those multiple views back into one:

  • From the dropdown menu, choose Window > Collapse Tab Groups.

Alternately, you can simply grab the document tab for a detached file and drop it onto an existing tab or tab group. When the icon changes to show a miniature window with tabs, release the mouse.

3.8.4.7 How to Quickly Close Files in the Editor Window

You can close any file open in the editor window with a single click.

To close the current file, choose one of the following ways:

  • From the main menu, choose File > Close.

  • Press Ctrl+F4.

  • In the editor, right-click the tab for the current file and choose Close.

  • Hover the mouse over the tab for the current file and click the Close button.

To close all files, choose one of the following ways:

  • From the main menu, choose File > Close All.

  • Press Ctrl+Shift+F4.

  • In the editor, right-click the tab for any file and choose Close All.

To close all files except one:

  • In the editor, right-click the tab for the file you want to stay open and choose Close Others.

To close multiple files at once:

  1. From the main menu, choose Window > Windows.

  2. In the Windows dialog, select the files to be closed and click OK.

To selectively close files:

  1. In the editor, select the corresponding tab for the file to be closed.

  2. Ctrl+click the tab, or hover the mouse over the tab and click the Close button.

3.8.5 Working with Mouseover Popups

Mouseover Popups enable you to position the mouse cursor over certain areas of the IDE and get some information on them in a popup window that appears floating in front. Information is available on the following:

  • Javadoc

  • Source code

  • Data values while debugging

  • Breakpoints

The popup window appears when you move the mouse over and optionally press the key that you assign for the feature. The following are some of the areas of the IDE that mouseover popups are available for:

  • Structure window

  • Text in an editor

Smart-Popup

The Smart-Popup feature shows the most appropriate popup for a given situation, depending on the order of popups specified in the Mouseover Popups page of the Preferences dialog. Smart-Popup is activated by a keystroke which you can specify on the Mouseover Popups page of the Preferences Dialog.

For example, you may have the following popup configuration (set using the Mouseover Popups page of the Preferences dialog)

  • Smart-Popup is enabled and configured on the Control key.

  • The Data Values, Documentation, and Source popups all have Smart-Popup enabled and are ordered in the following way: Data Values, Documentation, Source Code in the Mouseover Popups table.

With this configuration, if you hover the mouse over a variable in the source editor and press Control, then:

  • The Data Values popup is considered first. If you are debugging and the mouse hovers over a variable with a value, the Data Value popup is displayed.

  • If no popup is displayed for the previous step, then the Documentation popup is considered next. If the variable has any documentation, it is displayed in a popup window.

  • If no popup is displayed for the previous step, then the Source popup is considered next, and the source code for the variable (if available) is displayed in a popup window.

With Smart-Popup, you only need to use the Smart-Popup activation keystroke for the IDE to display the most appropriate popup

Note:

Even with Smart-Popup enabled, the individual popups for Data Values, Documentation, and Source Code can still be activated by their respective activation keys.

3.8.6 How to Locate a Source Node in the Navigator

You can quickly locate the source node in the Application Navigator for any file opened for editing, whether or not that node is in the current project.

To locate the node for any file opened in the editor:

  1. Make sure that the focus in the editor is on the file you wish to locate.

  2. From the context menu, choose Select in Navigator.

3.8.7 How to Set Bookmarks in Source Files

You can use bookmarks in your source files to help you quickly locate relevant code. You can use the Bookmarks Window to navigate to bookmarked material.

To set or remove a bookmark in a source file:

  1. Within the file, place the cursor in the gutter of the line you would like bookmarked.

  2. Right-click and choose Toggle Bookmark.

3.8.8 How to Edit Source Files

Oracle JDeveloper provides several features for editing source files.

3.8.8.1 How to Open Source Files in the Source Editor

JDeveloper provides a powerful source editor that will help you write different kinds of code quickly and efficiently.

You can set preferences for the specific editor for each file type.

To open your source code in its default editor:

  • In the Application Navigator, double-click the file or right-click and choose Open.

    The default editor associated with that file type appears in the content area. If the editor is already open on that file, the editor comes to the foreground.

To open your source code in a specific editor or viewer:

  1. In the Application Navigator, double-click the file or right-click and choose Open.

  2. In the editor window, select the appropriate editor tab.

Changes made in the source will be immediately reflected in other views of that file.

You can also generate Java source code from modeled Java classes.

3.8.8.2 How to Edit Source Code with an External Editor

It is possible to edit source code that you have opened in JDeveloper with an outside editor, should you wish to do so. When you return to the JDeveloper IDE, it will detect the changes you have made.

Before you edit a file externally, you should first save any changes made in JDeveloper. If you do not, when you return to JDeveloper, you will be asked whether to reload those files or not. If you reload the externally modified files, you will lose the unsaved changes made in JDeveloper. If you do not reload them, you will lose the changes made outside JDeveloper once you save the file in JDeveloper.

To edit source code with an external editor, with the file open in JDeveloper:

  1. Save any changes made to the file open in JDeveloper.

  2. Edit your file externally and save your changes to the disk.

  3. Return to JDeveloper and to the file open in the source editor.

    By default, the file is reloaded in JDeveloper without a confirmation beforehand. To receive a confirmation dialog, deselect the Silently Reload When Buffer Is Unmodified option on the Environment page of the Preferences dialog.

3.8.8.3 How to Insert a Code Snippet from the Component Palette into Source Files

Once you have added code snippets to the Component Palette, you can add them to files open in the editor.

Alternatively, you can use code templates to assist you in writing code more quickly and efficiently while you are in the source editor.

To insert a code snippet from the Palette into a source file:

  1. Open the file in the source editor.

  2. If the Component Palette is not visible, open it by choosing View > Component Palette.

  3. In the Palette dropdown list, select Code Snippets or the snippets page you have defined.

    The snippets defined for that page appear listed to the right. Toggle between list and icon views by right-clicking and choosing the view you want from the context menu.

  4. Position your cursor in the file at the point where the snippet is to be inserted.

  5. In the Palette, click the snippet name or icon.

The code snippet appears in the file.

3.8.8.4 How to Record and Play Back Macros in Source Files

3.9 Working with Extensions

Most of the basic functionality in JDeveloper is implemented as extensions—software packages which add features and capabilities to the basic JDeveloper IDE. You can add existing extensions into JDeveloper, or create your own.

Extensions are components that are loaded and integrated with JDeveloper after it is started. Extensions can access the IDE and perform many useful tasks. In fact, much of JDeveloper itself is composed of extensions.

This section contains information on finding, installing, and enabling or disabling JDeveloper extensions. The simplest way to find and download JDeveloper extensions is through the Check for Updates wizard.

If you need additional capabilities from the IDE (such as integration with a version control system or a special editor or debugger), you can add external tools to JDeveloper. See Section 3.12, "Adding External Tools to JDeveloper" for more information.

In addition, you can obtain additional extension development tools and functionality in the Extension Software Development Kit (SDK). You can download the Extension SDK via the Check for Updates wizard.

You can also download the Extension SDK from the Oracle Technology Network Web page.

Note:

Any time an extension is added or upgraded, the migration dialog appears at startup in case you need to migrate any previous settings related to that extension.

3.9.1 How to Install Extensions with Check for Updates

The easiest way to find and install extensions is to use the Check for Updates wizard.

To install extensions using the Check for Updates wizard:

  1. From the Help menu, select Check for Updates.

  2. Follow the steps in the wizard to browse, download, and install patches and extensions.

You can also access the Check for Updates wizard from the Tools > Features page.

3.9.2 How to Install Extensions from the Provider's Web Site

Some extension providers prefer to have you install directly from their Web site, so that among other things they can contact you when there are updates to the extension. In this case, the Check for Updates wizard will inform you of the provider's preference, and will then open your default Web browser so that you can conduct the download and installation from the provider's Web site.

To download and install from the provider's Web site:

  • Follow the instructions on the provider's Web site for downloading and installing the extension. Be sure to note any comments or instructions on registration, configuration, or other setup requirements.

3.9.3 How to Install Extensions Directly from OTN

You can find and download extensions from the JDeveloper Extensions Exchange website on OTN. The page is located here:

http://www.oracle.com/technetwork/developer-tools/jdev/index-099997.html

The available extensions include:

  • JUnit Extension, an extension you can use to create and run test cases, test suites, and test fixtures, using JUnit.

  • iSQL*Plus Extension, an extension that enables you to load or execute SQL*Plus scripts from within JDeveloper.

  • Oracle Business Intelligence Beans, a set of standards-based JavaBeans™ that enables developers to build business intelligence applications.

  • Other extensions to JDeveloper contributed by the JDeveloper community.

To install extensions after you have downloaded them from OTN:

3.9.4 How to Install Extensions Using the JDeveloper dropins Directory

JDeveloper supports the concept of a "watched directory". A watched directory is a location where a user or script can drop files and have them discovered by JDeveloper automatically the next time it starts.

To install an extension using the dropins directory:

  • Drop your extension jar in the JDeveloper dropins directory, which is located in the jdeveloper/dropins folder.

  • Additional dropins directories can be specified via the ide.bundle.search.path property, either at the command line or by adding an entry in the jdev.conf file.

3.10 Using the Online Help

You can access the JDeveloper online help through the Help Center. This section describes how you can effectively use the features of the Help Center.

3.11 Common Development Tools

This section provides an introduction to fundamental JDeveloper IDE functionality and concepts.

3.11.1 Application Overview

Use the Application Overview pages to guide you as you build a Fusion Web application, and to create files and objects and view the status of them.

3.11.1.1 Checklist

The Application Overview Checklist steps you through the building of a Fusion Web application, according to Oracle recommended best practices. The Checklist is displayed by default when a Fusion Web application is created, as part of the Application Overview pages.

The checklist optionally walks you through the entire process of configuring and building your application, with links to specific dialogs and wizards. Each step is also designed to teach you about the architecture, tools and resulting files using a combination of links to step-by-step instructions, relevant sections of the Developer's Guides, and descriptions of what happens in the IDE as a consequence of doing the work in a step.

Unlike a wizard, the Checklist itself is intended to provide a linear, but ultimately flexible and lightweight guide. You can follow the prescribed path in exact sequence, or explore tasks in a different preferred order. When using the Checklist, it suggests a best way to accomplish your goals, but you are not restricted by it. You can also close the Application Overview and work directly in the IDE, or work in both the IDE and Checklist interchangeably.

To use the Checklist:

  • Expand a step and read the prerequisites and assumptions.

    Checklist Step 1: Expand a step
  • Optionally click any of the documentation links.

    Documentation links
  • Click the button that takes you to the relevant area of the IDE.

    Launch a dialog
  • Use the status indicator dropdown to change the status as you work through tasks.

3.11.6 Structure Window

The Structure window offers a structural view of the data in the document currently selected in the active window of those windows that participate in providing structure: the diagrams, the navigators, the editors and viewers, and the Property Inspector.

Depending on the document currently open, the Structure Window enables you to view data in two modes:

  • Source - displays the code structure of the file currently open in the editor. Applicable to technologies that allow code editing. For example, this tab will not be available when a diagram is open for editing.

  • Design - displays the UI structure of the file currently open in the editor.

In the Structure window, you can view the document or diagram data in a variety of ways. The structures available for display are based upon document or diagram type. For a Java file, you can view code structure, UI structure, or UI model data. For an XML file, you can view XML structure, design structure, or UI model data.

The Structure window is dynamic, tracking always the current selection of the active window (unless you freeze the window's contents on a particular view), as is pertinent to the currently active editor. When the current selection is a node in the navigator, the default editor is assumed. To change the view on the structure for the current selection, select a different structure tab.

The windows that participate in providing structure also follow selections made in the Structure window. Double-clicking the node for a method in the Structure window, for instance, makes the source editor the active view and takes you directly to the definition for that method.

You can open multiple instances of the Structure window, freezing the contents of any number of them, in order to compare the structures of different files. You can also switch structure views without changing editors.

Diagram objects (such as UML elements) listed in the Structure window can be dragged from the window and dropped directly onto diagrams.

3.11.6.1 Structure Window Toolbar

The following table describes the icons in the Structure Window toolbar and their functions:

Table 3-36 Structure Window Toolbar Icons

Icon Name Function
freeze

Freeze

Click to freeze the Structure window on the current view. A window that has been frozen does not track the active selection in the active window.

new view

New View

Click to open a new instance of the Structure window. The new view appears as a tabbed page in the same window.


3.11.6.2 Structure Window Views

The Structure window view depends upon the document type of the current selection in the active window. Each view offers different options for viewing and sorting the structure of your files based on file type.

The following table describes the Structure Window views.

Table 3-37 Structure Window Views

View Description

ADF Business Components View

When you select any ADF business component in one of the navigators, the Structure window offers a structured view of the component's files, attributes, and other properties.

Cascading Style Sheet View

This view allows you to select and group CSS elements for easy editing. When a CSS file is open for editing, CSS selectors in the file are displayed in the Structure window as one of three types: Element, Class, and ID.

Java View

This view displays the code as well as design structure of the Java file currently being edited. Additionally, you can specify several display preferences to view structural data.

JSP/HTML View

This view displays the code structure and UI bindings for the JSP/HTML file that is currently selected.

Struts View

The Struts view shows the hierarchy of elements and attributes for the Struts configuration file currently selected in the active navigator or editor.

TopLink View

The TopLink view displays detailed information about the TopLink element selected in Application Navigator or TopLink editor, including descriptors, sessions, and mappings.

UML View

The UML view displays the behavior, interaction, and code structure in UML-based diagrams such as Activity Diagrams, Class Diagrams, and Use Case Diagrams.

Diagram View

When a diagram is open for editing, the Diagram view displays the components that have been added to the diagram. You can select an element in the Structure Window's diagram view and locate it in the diagram


3.11.7 Application Navigator - Data Controls Panel

Use to view the data controls created to represent an application's business services and to create databound UI components by dragging and dropping the control panel objects onto an open web page or ADF Swing panel.

Note:

The Data Controls panel may appear empty if no data controls have been created for or imported into the application.

The panel displays objects to which your UI components can be bound, including data collections, attributes, and methods that the business services developer exposed through the Oracle ADF data control, as well as specific, built-in operations that are generic to all data collections.

When you drag an object from the Data Controls panel onto a page, the context menu displays the UI components you can create for that specific object. Creating components this way means that they will automatically be databound to the dropped object.

After inserting a databound UI component into the displayed web page or Java panel, you can view the Oracle ADF data binding:

  • In the code view of a web page, where data binding objects appear in expressions that get evaluated at runtime using the expression language features of the JSTL tag library.
