Issue with EJB 2.0 MDB, WAS 6.1

[arvi...@yahoo.com]

I am using WAS 6.1. I created a new EJB Project and picked J2EE 1.4 and EJB2 while doing that. I have a simple MDB that does nothing but print out a message to the console in the onMessage method. This MDB should get triggered when a message arrives on a Queue called IN.Q , jndi name jms/IN.Q.
I can deploy and install the application using the Admin console but when i try to start the app I get this error: Can someone point me to what I am doing wrong here? Thanks!

I have attached the ejb-jar.xml. Here is the ejb-jar-bnd.xmi:

[Note, this answer also was posted to the EJB 3.0 feature pack beta forum where the question was originally posted.]

Hi,
Judging from where the exception is happening, it looks like you may not have run the EJBDeploy tool on your EJB 2.0 module. If your module is 2.1 or earlier, you still need to run EJBDeploy; the new Just-In-Time deployment feature only applies to modules at the EJB 3.0 level.

Regards...Randy

Thanks!
