I'll take a closer look to @LocalClient which I overlooked. But as you point
out, this will not apply directly to my issue.

Great, these classes seem to fit my needs !

Well I think it could be a valuable add to OpenEJB (not mentioning my own
interrest :thinking: ).
If I am allowed to speak my dreams, I can easily think of an embedded
OpenEJB client (with RemoteICF) as a seamless "gate" to the server it links
to... Providing that :
- the RemoteICF is able to manage it's own EJBs (just like the LocalICF
does)
and inject them with EJBs coming from the server
- the server is able to participate in transactions managed by the client
Well this might be a terrible idea, let me know...
