This illustration shows the structure of a J2EE BMP bean application. The BMP EJB module JAR contains the `orion-ejb-jar.xml` file: because there are BMP entity EJB, the `orion-ejb-jar.xml` file must contain `persistence-manager` subentries. In this case, there is no domain module JAR file. The contents of the `project.xml` file is in the `toplink-ejb-jar.xml` file which is packaged in the BMP EJB module JAR. There is no `sessions.xml` file because the TopLink runtime creates, configures, and acquires a session internally based on the `orion-ejb-jar.xml` file `persistence-manager` subentries
