This is possible (at least with Oscar 1.0.5.), there are some concern
you have to take into account. First you need to make sure you use the
correct classloader to get to the classes embedded in the bundles.
That should be too hard a problem.
Can you elaborate on this point? Is it about setting the correct
thread's context classloader?
What doesn't work well is synchronizing the oscar loaded objects
across a cluster and serializing the objects into the session.
Though the serialization works pretty well, the receiving side can't
instantiate the objects, as the classes can't be found by the servlet
container's classloader.
Right. That's where having the servlet engine running as a bundle makes
a difference.
The Wicket framework has run into this problem as well. Everything
works quite well when run in a whole OSGi environment, but when
there's a mix'n'match with classloaders your in for some hard
thinking. We woul also like to see some solution for this problem ;-)
Bright ideas are welcome!
Thanks for this answer!
