This is code which is generated when the ejb is created...
it seems as though the value of CONNECTION_FACTORY_JNDI_NAME maybe an empty
string when called in the getQueueConnection() method (no params) above. I have
no control over this code or it's parameters?
The value of objRef when the last method is called, the method in which the
exception occurs.
| objRef NamingContext (id=263)
| env Hashtable<K,V> (id=265)
| naming NamingServer (id=270)
| parser NamingParser (id=274)
| prefix CompoundName (id=277)
