Chapter 7 Creating J2EE Applications for IBM WebSphere 5.0

Creating EJBs

To create EJBs, you need to:

• Define classes using class diagrams.
• Define a database schema using a Physical Data Model (PDM).
• Define the O/R mapping.
• Convert classes to EJBs or new EJBs.
• Define EJB properties.

For more information about how to use class diagrams, how to design a database, how to define O/R mapping and how to create EJBs, refer to the core PowerDesigner documentation.
