[jboss-user] [JBoss jBPM] - Could not instantiate TransactionManagerLookup

[greenHand]

I have the jbpm-enterprise.ear deployed in Weblogic 9.2.3. The jndi to the data source is also setup. I wrote a message driven bean to invoke jbpm with the following onMessage() method:
	public void onMessage(Message msg) {
  | 		try {
  | 			InitialContext ctx = new InitialContext();
  | 			
  | 			RemoteCommandServiceHome commandServiceHome = 
  | 				(RemoteCommandServiceHome) ctx.lookup("ejb/CommandServiceBean");
  | 			RemoteCommandService commandService = commandServiceHome.create();
  | 			commandService.execute(new NewProcessInstanceCommand("MyProcessDef"));
  | 		}
  | 		catch (NamingException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 		catch (RemoteException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 		catch (CreateException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 		catch (Exception e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 	}
However, I got the "Could not instantiate TransactionManagerLookup" error when the message is received:
