After you have installed an EJB 2.X as a JAR archive or an exploded directory, it is displayed in the Deployments table, where you can access and configure it.
A table that lists the deployments currently installed on WebLogic Server appears in the right pane. The Type column specifies whether a deployment is an enterprise application, a Web application, or an EJB.
Note: You must create a Work Manager before you can associate it to the EJB.
