Finally: PROBLEM SOLVED.
The short hint from Luke Nelson turned out to be the ultimate proof of what
theese mailing lists are really worth.
Luke is right, guys. To be able to reference other EJBs from within EJBs you
need to put a <ejb-link> tag in your ejb-jar.xml file. How this is done can
be seen on page 417 of the EJB-2.0-spec - I have used it and it works (once
you get the syntax right). So there is really no need to create special
Orion-specific lookups like P. Pontbriand has been doing - I tried P.
Pontbriands solution, but could not make it work, which was why I moved on
to the <ejb-link>-solution.
Still, to the best of my knowledge, it should only be necessary to add the
<ejb-link> if your beans reside in different jars - so, the fact that Orion
users need to add this tag even with beans residing in the same jar is an
error (I assume).
One happy developer - you made my day, Luke!

Have you tried putting an ejb-link reference in your ejb-jar.xml? Just an
idea.

Thanks, Klaus - but the strange thing is, I have tried carrying out the
exact same lookup from within my JSP and within my EJB - for instance:
UserHome userHome = null;
object = context.lookup("java:comp/env/ejb/UserHome");
userHome = (UserHome) PortableRemoteObject.narrow(object, UserHome.class);
It works in my JSPs but inside my EJBs it throws a NameNotFoundException.
Any ideas???

You work with EJBs inside another EJB the same way as you do inside a JSP
Remember you have to use the JNDI name, not the home interface name, so a
lookup("ejbSomeExample") will ofcourse return the home interface :)
Hope this helps (ps remember ejb-refs to the objects you wish to use from
the bean you are calling from or it will not work..

Emne: Getting the home interface of another EJB from within an EJB
>From inside an entity bean you can get hold of your Home interface by
calling
myBeansEntityContext.getEJBHome()
but how do I get hold of the home interface of _another_ bean?
I assume this requires some kind of lookup. In JSP files one would simply
use "new InitialContext()" and perform a lookup on this context, but if I do
so within an EJB, I am not able to find any home interfaces at all - I get a
NameNotFoundException.
Now, is it really necessary to go all the way and get an InitialContext by
setting up environment properties and creating an InitialContext from these
plus adding an "application-client.xml" to the deployment....?? - After all
I am still inside an EJB...
Any hints would be appreciated.
