For 2.x CMPs, you can specify a backend ID for the database type
that you are deploying to. The backend ID determines the persister classes
that get loaded at deployment.
To define the backend ID for database type:
- Switch to the J2EE perspective.
- In the Project Explorer view, select the desired EJB module.
- Right-click on the Deployment Descriptor Editor and
select Open With from the pop-up menu.
- On the Overview page of the editor, select
the Backend ID section under WebSphere® Bindings.
- Select a database from the drop-down list. You can also refresh
the backend ID.
