--------------------------------------------------------------
I am trying to deploy 2 MDBs in a standalone XP machine running JBoss 6 M2. I am getting
the following exceptions in my server.log
I do have a ejb-jar.xml but I gather I do not need one since I have EJB3, but I do have
session beans that are from EJB 2.0.
I have configured an Mysql datasource and necessary queues in the appropriate xml files,
but it is apparent I am not doing something right somewhere. How can I solve this problem?
Any pointers in resolving this issue are appreciated. Thanks in advance.
The errors are below:
