Hi,

I have some EJB3 MDBs which were working fine with JBoss 4.0.4.GA, JBoss Messaging1.0.1.CR5 and EJB3 RC8. The only issue was that I could not start/stop the MDBs using JMX. Reading through the forums it looked like this was fixed in RC9 build of EJB3. 

I installed the EJB3 RC9 using the ant script and followed the migration (RC8 - RC9) notes. On restarting initially got the error saying the jms-ra.rar was already registered. To fix that, copied the deploy/jms/jms-ra.rar to deploy/jms-ra.rar replacing the existing jms-ra.rar and deleted the jms directory.

That got rid of that problem but I keep getting the following: 


MIPServer.jar,name=TestMDB,service=EJB3
java.lang.NullPointerException
        at org.jboss.ejb3.mdb.MDB.getMessagingType(MDB.java:85)

I am sure I am missing some step here but cannot find what exactly it is. MDB looks like the following

@MessageDriven(activationConfig =
{
		@ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Topic"),
		@ActivationConfigProperty(propertyName="destination", propertyValue="topic/topicname"),
		@ActivationConfigProperty(propertyName="durability",propertyValue="Durable"), 
		@ActivationConfigProperty(propertyName="clientId",propertyValue="ClientID"), 
		@ActivationConfigProperty(propertyName="noLocal",propertyValue="true"),
		@ActivationConfigProperty(propertyName="subscriptionName",propertyValue="SubName")
})


Thanks for the help.
