Wicket serialization problems for OSGi users
I know there have been a few people inquiring about this from time to
time.
I write about my experiences here, in the hope that this is helpful:

Hi David,
Thank for your answer! Yes, your are right buddy class loading is Equinox
proprietary. For me that's not a problem because I tied myself to use
equinox. I did so because if you want to deploy in a traditional application
sever you will have to use a bridge approach and equinox already provide
that bridge. I though the standard already provided a something similar to
buddy class-loading (dynamic imports?), or at least that was the answer
some-one gave to me on the equinox list. I haven't had the time to check the
details myself. For me, buddy-class loading works just fine and I didn't
bother too much with the philosophical implications of this. I also need
the same trick for things like loading entities, quartz jobs, etc.
Cheers,
Ernesto

Simple: at least for now, this is a non-standard extension for Eclipse/
Equinox. :-)
I am aware of some proposals to modify the OSGi spec, but as far as I
know, that's not getting anywhere yet. In any case, I am still
pondering over whether or not the framework should even directly
serialize those private classes... Haven't yet come to any conclusions.

Hi David,
Nice post! Just one question why not use buddy class-loading techniques to
"solve" serialization problem? To me this is the same kind of problem you
encounter when you have a basic bundle handling Hibernate persistence and
you want Hibernate to load classes from a bundle containing your entities.
Or am I missing something?
Best,
Ernesto
