Greetings, Kesav.
I have had to chase down a few instances of this myself. A useful tool
I found was the orionconsole.jar. It is still alpha, with lots of
missing functionality, but one thing that is working is the ability to
read Orion's JNDI tree. A little hunting should tell you what the name
is and where your ejb is registered. I found that unless everything is
perfectly specified in the XML files, Orion has a tendency to
auto-generate JNDI names that may not be what your code is looking for.
This would be one way to verify what is going on.
