Creating a Diagram of Enterprise JavaBeans

Entity, session and message-driven beans, their properties and methods, the relationships and references between them can all be modeled graphically on an EJB diagram. EJB diagrams can also be used for modeling UML classes, Java classes, UML use cases, offline database objects, business components and web services.

To create a diagram of Java classes:

Create a new EJB diagram in a project or application using the EJB Diagram icon in the New Gallery. For more information, see Create a New Diagram.
Create the elements you require on the diagram using the EJB Component Palette.
