Interesting proposal... The ejb spec requires all access to ejbeans be
done via proxy (container), but says nothing about direct access to bean
components (at least I don't think).
If you want to pursue this further, perhaps you should have the bean
component subscribe/unsubscribe during callbacks to set/removeEntityContext;
this way you are guaranteed the correct InitialContext, and that messages
are received only when the bean is active!
If this doesn't work, trying messaging ejb via JMS proxy, as described
nicely (with source code) in the current issue of JDJ:
http://www.sys-con.com/java/archives/0506/grant
Or use EJB 2.0's MessageBeans!
Good luck!

Subject: Can an EJB contain JMS subscribers?
Folks,
If I have an enterprise bean (session or entity) which in turn is
composed
of several other objects, is it acceptable for those objects to
subscribe
to JMS messages? Is this behaviour portable between application
servers?
Can the contained objects simply get the InitialContext by instantiating
it
(in the same way that the bean class does - in EJB 1.1 anyway) and then
getting the JMS provider - or would the InitialContext have to be handed
to
them by the bean class?
I'm doubtful, since this seems to break restrictions EJB places upon
multithreading... but let me know what you think!
Regards,
James W.
