Using JDeveloper to Build Oracle XML Applications, 2 of 11

## Introducing JDeveloper 3.2

JDeveloper Version 3.2, offers an integrated, full-featured application development tool for building and deploying applications in Java and XML.

You can use JDeveloper to build, debug and deploy Internet applications that create and process XML data and documents.

Oracle JDeveloper 3.2 simplifies the task of working with Java application code and XML data and documents at the same time. It features drag-and-drop XML development modules. These include the following:

- Color-coded syntax highlighting for XML

- Built-in syntax checking for XML and Extensible Style Sheet Language (XSL)

- XSQL Pages and Servlet support, whererby developers can edit and debug Oracle XSQL Pages, Java programs that can query the database and return formatted XML, or insert XML into the database without writing code. The integrated servlet engine allows you to view XML output generated by Java code in the same environment as your program source, making it easy to do rapid, iterative development and testing.

- Includes Oracle's XML Parser for Java

- Includes the XSL-T Processor

- Related JavaBeans components

- XSQL Page Wizard. See "Page Selector Wizard" .

- XSQL Element Wizard. See "XSQL Element Wizard" .

- XSQL ActionHandlers

### Business Components for Java (BC4J)

Oracle Business Components for Java is a 100%-Java, XML-powered framework that enables productive development, portable deployment, and flexible customization of multi-tier, database-savvy applications from reusable business components.

Application developers use the Oracle Business Components framework and Oracle JDeveloper 's integrated design-time wizards, component editors, and productive Java coding environment to assemble and test application services from reusable business components.

These application services can then be deployed as either CORBA Server Objects or EJB Session Beans on enterprise-scale server platforms supporting Java technology.

The same server-side business component can be deployed without modification as either a JavaServer Pages/Servlet application or Enterprise JavaBeans component. This deployment flexibility, enables developers to reuse the same business logic and data models to deliver applications to a variety of clients, browsers, and wireless Internet devices without having to rewrite code.

In JDeveloper, you can customize the functionality of existing Business Components by using the new visual wizards to modify your XML metadata descriptions.

### Oracle JDeveloper XML Strategy

This chapter steps you through developing a mobile application using the XML components in JDeveloper. It also provides a roadmap for JDeveloper's XML support. It describes the XML support currently available in JDeveloper as well as JDeveloper's future direction.
