Since MyEclipse 5.5 supports JEE5, you can create a new EJB3 project by using the new EJB project wizard.

If you wish, the wizard can generate a persistence.xml file for you automatically (optional).

Here is a sample of the generated code after reverse engineering.

From the toolbar, you can use the new EJB3 bean wizards to generate Entity, Session and Message Driven beans.

In MyEclipse 5.5, you can now add JPA capabilities to any Java project.

MyEclipse allows you to select either Toplink or Hibernate as your JPA implementation.

Create a persistence unit easily using existing connection details.

Here is an example of a generated persistence.xml file.

Here is an example of some generated code from the JPA reverse engineering.

The JPA Entity Validator validates your entity annotations.

Referenced tables and columns are validated against your schema.

Annotation and mapping errors are also detected.

The MyEclipse Java Persistence perspective presents a convenient organization of views for working with JPA and EJB3 projects.

The Persistence properties view allows you to easily add new annotations and edit existing annotations without having to know JPA annotation specifics.

The table and column lists will be automatically populated with values from your schema.

You may change the database and schema your project is associated with using your project's Persistence Properties page at any time.

If your schema has changed, the changes can be picked up by using the Rebuild JPA Metadata action. Your project will be automtaically validated against the updated schema.

Entities generated during reverse engineering are automatically added to the persistence.xml file. If you have unlisted entities in your project, use the Synchronize JPA Entity Classes action.
