Hello everybody. I am developping 2 ejb-jar modules (let's name them A and B for readibility). These ejb-jars will eventually reside in the WEB-INF/lib of a war module, as per the Collapsed EAR architecture. Both ejb-jar files contains entities and stateless files. The difference is that A depends on B : B defines a set of classes which are parent entities for some classes in A.
Furthermore, A contains a stateless bean (MyManager) which requires to be injected whith the persistence unit. In fact, MyManager acts as a manager for the entities in A. At the war level, I define another persistence.xml in WEB-INF/classes/META-INF : <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"; > <persistence-unit name="acme"> <provider>org.hibernate.ejb.HibernatePersistence <jta-data-source>commonsDatabase <non-jta-data-source>commonsDatabaseUnmanaged <jar-file>../lib/A.jar <jar-file>../lib/B.jar <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" /> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.format_sql" value="true" /> <property name="hibernate.use_sql_comments" value="true" /> <property name="hibernate.transaction.manager_lookup_class" value="org.apache.openejb.hibernate.TransactionManagerLookup" /> </properties> </persistence-unit> </persistence> At startup, the persistence unit loads just fine, every entity is mapped and some code I wrote at the war level can successfully crud the entities in A or B. But, since A and B does not contain any persistence.xml, the injection of the persistence unit in MyManager fails. Here is what I get at startup : INFO - openejb.home = D:\projets\CCV-Core\CCV-Core-TestMain INFO - openejb.base = D:\projets\CCV-Core\CCV-Core-TestMain INFO - Configuring Service(id=Default Security Service, type=SecurityService, provider-id=Default Security Service) INFO - Configuring Service(id=Default Transaction Manager, type=TransactionManager, provider-id=Default Transaction Manager) INFO - Configuring Service(id=commonsDatabase, type=Resource, provider-id=Default JDBC Database) INFO - Configuring Service(id=commonsDatabaseUnmanaged, type=Resource, provider-id=Default JDBC Database) INFO - Configuring Service(id=Default JDK 1.3 ProxyFactory, type=ProxyFactory, provider-id=Default JDK 1.3 ProxyFactory) INFO - Found EjbModule in classpath: D:\projets\CCV-Core\CCV-Core-TestMain\target\WarApp\WEB-INF\lib\A.jar INFO - Found EjbModule in classpath: D:\projets\CCV-Core\CCV-Core-TestMain\target\WarApp\WEB-INF\classes INFO - Found EjbModule in classpath: D:\projets\CCV-Core\CCV-Core-TestMain\target\WarApp\WEB-INF\lib\B.jar INFO - AntiJarLocking enabled.

How can I make it possible for A to gain access to the exact same instance of acme persistence unit that is created later on ??? I'm a beginner in developping EJBs, so I hope that you are not smiling and thinking "young padawan, you need more basic training" :-D Seriously, I really tried hard, crawled throuh the JSR 220 for the past few days w/o reading anything that rang a bell for me. So any help would be appreciated.
