OSGI on google app engine?

Question

I am evaluating several technologies for an open source app for the google app engine. I'm searching for information regarding OSGI on googles app engine.

I have found Lemmon but it seems to be a dead project. The last checkin was in mid 2009... :-/ There is also a eclipse blog entry from april 2009, but it's not a real success story.

Has anyone successfully used OSGI in a GAE app?

Answer 1

The biggest single problem with this is the incompatability between the OSGi framework & GAE regarding thread management.

GAE manages threads (and machine instances) for you and makes it hard/controlled how you deal with threads in your own application. OSGi really does the opposite.
