[jboss-user] [EJB 3.0] - MDB in seperate ejb-jar causes problem during deployment

I'm fairly new to MDB and need some help. My ear has got the following structure ear | |-- entities-ejb | | |-- META-INF | | | |-- persistence.xml | | | |-- other-ejb | | |-- MyMessageDrivenBean | | | |-- war The MDB caused the deployment to fail over the persistence.xml in the other jar. This is from the startup log: xx:xx:xx,xxx WARN [ServiceController] Problem starting service persistence.units:ear=my-ear-1.0-SNAPSHOT.ear,unitName=my-ds | javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial | at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645) | at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247) | at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:284) | at javax.naming.InitialContext.lookup(InitialContext.java:351) | at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:216) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | .... and more When I put the MDB with the entity beans everything deploys fine and the applications including messaging works perfectly. I also tried to specify jndi.properties but this didn't seem to help. There are posts about multiple ejb jars and entities in them sharing a single persistence.xml but I couldn't find one addressing this particular issue. Any help is greatly appreciated!
