Hello,

Imagine the case where I want to call an EJB (statefull session or entity
for example) to tell him to perform some action, let's say to download a
file for example.

What I would like is that the EJB gives back the hand directly to the client
(i.e. the method call returns) but continues to perform its lenghty process
in the background. When finished, it calls back the client (through a
reference given during the first method call) and tell him the download is
finished.

This does not seem to fit in the EJB concept. Am I wrong?

How to implement these call-back and server background processing with the
EJB?

Thank you. Cheers,




                                Sacha
