Displaying the Implementing Java for a Modeled Bean

Each modeled bean has underlying Java source files which contain the implementation code for that element. These implementation files can be displayed on the diagram as modeled Java classes.

To display a modeled implementing Java classes for a modeled bean:

Select the bean on the diagram, the Java implementation of which you want to model on the diagram, then choose Model | Show | Implementation Files.

OR
Right-click the bean on the diagram, the Java implementation of which you want to model on the diagram, then choose Show Implementation | Files.
