I am having trouble deploying a session bean and three entity beans. I use jboss-4.0.4.GA. This is part of another issue (http://www.jboss.org/index.html?module=bb&op=viewtopic&t=91339) which troubles me. I get this is my log: anonymous wrote : --- MBeans waiting for other MBeans --- | ObjectName: jboss.j2ee:jar=concept.jar,name=EntityServiceBean,service=EJB3 | State: NOTYETINSTALLED | I Depend On: | persistence.units:unitName=proof | | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- | ObjectName: persistence.units:unitName=proof | State: NOTYETINSTALLED | Depends On Me: | jboss.j2ee:jar=concept.jar,name=EntityServiceBean,service=EJB3 This is the persistence.xml: <?xml version="1.0" encoding="UTF-8"?> | <persistence> | <persistence-unit name="proof"> | <jta-data-source>java:/DefaultDS</jta-data-source> | <properties> | <property name="hibernate.hbm2ddl.auto" value="create-drop" /> | </properties> | </persistence-unit> | </persistence> This is the declaration of the entity manager in my session bean: @PersistenceContext(unitName = "proof") | protected EntityManager manager = null; | What might be causing that the persistence unit is not getting deployed?
