Content provided under the terms and conditions of the Eclipse Public License Version June Eclipse Foundation - EJB Generation Framework ■ Component in JST –EJB Generation using Datamodels and Operations ■ Functional Overview –The framework provides a means for defining EJB components using DataModels, and provides and extensible way of generating ejb components using operations. –Provides extensible wizards to define and trigger EJB generators –Provides an example generator using XDoclet ■ Extensible –IEJBGenerator extension point –Nested wizards to insert specific UrIs –Nested models to extend the models.

Content provided under the terms and conditions of the Eclipse Public License Version June Eclipse Foundation - EJB Model ■ J2EE models for ejb are available in JST EMF models Reflect the standards view of an ejb org.eclipse.jst.j2ee.ejb ■ EJB tooling needs more Seperate the following views ► J2EE Standard x Tooling API x Runtime Extensions We use the delegate pattern to avoid the coupling that can make j2ee models hard to maintain.
