Hi,
From your exception message, it looks like resource references are being used to lookup the queue.
In which case, it should be specified as
java:comp/env/......
But in the exception, I could only see that you are trying to lookup comp/env/...
Verify it once if you have mentioned the resource reference properly as java:comp/env/...
If the above is specified properly, try running the dumpNameSpace utility and verify if the queue jndi name is bounded.
