I would be careful with the "required" java:comp/env/ portion, depending on
how it is declared orion doesnt necessarily bind the home to the right
context. We found this out when we were looking at the orion primer
tutorial. the home object there was actually bound to the root context (i.e.
no java:comp/env/) a good tool to look at these things is Forte For Java. It
has a JNDI browser built into it.
