Hi,
unfortunately I have some bad news for you. My earlier post was a little premature, the solution I posted didn't work reliable enough, so we switched back to V2.1.1. That is also why I don't have my original manifest files anymore. I took a look at your manifest and from what I remember it looks similar to mine, only I had this line included:
Eclipse-BuddyPolicy: dependent.
I had to change the classloading policy because my glassfish plugin needed to access classes that were defined in a different plugin.
Anyway, your exception looks a bit different, although it appears to be a classloading issue, too.
As for the jars, I tried to add fewer jars, but at some point there was always one jar missing and I ended up including all.
Sorry, I couldn't really help you.
Stephan
