For 2.x CMPs, you can specify a back-end 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 back-end 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 list. You can also refresh the backend
ID.
