Changing Client Data Model References for JClient Forms

You do not need to edit your application code to change the data model definition it will use to connect to your business services data source. The definition is contained entirely in the meta-data for the JClient project in two files: DataBindings.cpx and UIModel.xml .

You might want to do this because you had been using a local configuration to test your application in JDeveloper and you now want to change to a data model definition that uses a remote deployment configuration. You could also decide to use an entirely different data model defined in a different business service project. Again, no code changes are required to accomplish this task.

To reference the new client data model definition in the JClient meta-data:

Add a new client data model definition to the DataBindings.cpx file in your JClient project and remember the name you chose (for example, remotedatamodel).

Note: If you change your data model to use an ADF Business Components application module from a package in a different project and the new application module is defined as Session Bean (BMT), then you must modify the <ejb-ref> entry in the web.xml file as well as update the .cpx file.
Optionally, you can open the DataBindings.cpx file in the XML editor and edit the attributes of the AppModuleDataControl:
1. Choose View | Structure to display the Structure window for the file.
2. In the Structure window, select the data control node you want to modify.
3. Choose View | Property I nspector to display the data control definition and edit its attributes.
Open the UIModel.xml file in the XML editor, display the Structure window and select any binding that references the old data control.
With the binding selected in the Structure window, open the Property Inspector and edit the Model Reference attribute so it names the new data model definition. Repeat for each binding in the binding definition.

Repeat for each panel or form in your JClient project so their own binding definitions have the same changes.
