Generating Java Code

This section explains some of the features of the Java object language in order to generate Java code from objects in the OOM.

EJB Subfamily

If you work on a Java OOM created in version 9.0, the subfamily of Java is EJB 2.0 and it supports EJB. In later versions, the subfamily of Java has become J2EE, it supports J2EE components (servlets, JSPs and EJB).

You should use the new Java object language provided with the current version to use J2EE components. If you had customized the Java object language in the previous version, you have to apply these changes manually in the new Java object language.

By default the WSDL for Java extended model definition is automatically attached to the model when you select the Java language. This extended model definition supports J2EE 1.3. However, if you want to support J2EE 1.4, you should use the list of extended model definitions to delete the WSDL for Java extended model definition and import the WSDL for Java (J2EE 1.4) extended model definition.

Defining Java Environment Variables
Variables used for Java generation are defined in the General Options dialog box.
Selecting Java Generation Options
You can set the following options, available from the Options page of the Generation dialog box in Java:
Selecting Java Generation Tasks
The following tasks are available from the Tasks page in the Generation dialog box for Java:
Generating Java Files
You generate Java source files from the classes and interfaces of a model. A separate file, with the file extension .java, is generated for each class or interface that you select from the model. A generation log file is also created at the same time. You can only generate Java files from one model at a time.
Working with Tools for Java Generation
This section briefly introduces some of the tools that can help you generate, compile, package and deploy components. You can do this within PowerDesigner, or use Ant or an IDE like JBuilder.
