Extend the WebSphere Commerce object model

Application requirements may lead you to extend the existing WebSphere Commerce object model. The WebSphere Commerce object model can be extended in two ways.

• Extending the WebSphere Commerce object model with session beans
  WebSphere Commerce has implemented core commerce objects using JPA entities.

• Adding new EJB projects
  You may have a requirement to create additional EJB projects, however your if you do, we must locate your JPA entity in the WebSphereCOmmerceServerExtensionData project.
