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
