RE: What does manager do anyway?
I now think that session data was wiped on a reload only if I made changes to one of the beans. It makes sense: If they get serialized at TC shutdown, but startup detects a different class signature, they can't be re-serialized... --- August Detlefsen [EMAIL PROTECTED] wrote: Yes.
