Adding fields to CMP entity beans in domain modeling class diagrams

You can use domain modeling class diagrams to add fields to container-managed persistence (CMP) entity beans and define them as key fields.

Before you begin

You must have a domain modeling class diagram open.

In the diagram editor, right-click a CMP entity bean; then click Add EJB > CMP Fields.
In the CMP Fields wizard, click Add.
In the CMP Attributes window, specify a name and a type for the CMP field, specify its array dimension or define it as a key field, and click Apply.
Click Finish.

A field is added to the CMP entity bean and is displayed on the diagram.

Tip: You can also use the action bars in the diagram editor or the EJB Deployment Descriptor to add fields to CMP entity beans.
