[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: How to connect my EJB to firebird database?

I do about that and try to do the simplest way. My persistence.xml is <?xml version="1.0" encoding="UTF-8"?> <persistence-unit name="order" transaction-type="JTA"> <jta-data-source>java:/FIrebirdDS</jta-data-source> </persistence-unit> My EJB begins with: @Stateless @RemoteBinding(jndiBinding="ejb/Person") public class PersonBean implements Person { //@PersistenceContext EntityManager em; When I deploy my .ear with this EJB, I get an error message in JBoss console with the last part: --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.jca:name=FIrebirdDS,service=DataSourceBinding State: NOTYETINSTALLED Depends On Me: persistence.units:ear=EJB3Test.ear,jar=EJB3Test.jar,unitName=order persistence.units:ear=EJB3Test.ear,jar=EJB3Test.jar,unitName=order persistence.units:ear=EJB3Test.ear,jar=EJB3Test.jar,unitName=order But nevertheless .ear is deployed and I can reach my PersonBean EJB from a remote client on JNDI name and call it's business method. But as soon as I uncomment //@PersistenceContext EntityManager em; and redeploy my .ear, I cannot reach PersonBean EJB any more - Object ref = context.lookup("ejb/Person"); in my client generates NameNotFoundException View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4007902#...
