Hi Richard,
Thanks for being kind in your responses. I believe you done a better
job than I have at describing how one might partition responsibilities
between components in your application.
The orginator of this thread was trying to make a call wait() in the EB,
which caused an exception to be thrown. The real question is, what
are the roles of EJB's and does this activity fit into that role?
My current thinking would be to model the listener/subscriber as a (as I
believe the patterns people call them) as a moderator between the EJB
and the client/publisher.

EJB/JMS integration is unspecified, but nothing prevents you from making
a simple proxy that delegates incoming JMS messages to beans. And then
you would communicate with the bean through the EJBObject, which would
give the behaviour Bernd outlined (as the proxy is only
yet-another-client).
I haven't actually tested this approach :-), but I see no reason why it
wouldn't work. The only thing that is extra-spec is the setup of it,
i.e. there's no specification of how these proxies are registered as
listeners etc.
