We're using SJSAS 9.1 UR2 with a support contract. So, these bug fixes
did not go into later update releases, correct? I don't think we can use
GlassFish V3 Prelude because I read somewhere that it isn't a full Java
EE 5 app server and we use a lot of Java EE 5 features. For GlassFish
2.1 we'll need to test our product on it before going into production.
Ideally I would be able to reproduce the problem first, then try
GlassFish 2.1 and see if I can still reproduce the problem.
Thanks,
Ryan
