I believe we should put a template for "error reporting" on the web site.
You CMP/BMP, etc etc...
I am not talking about "Bugs" just "it doesn't work, it is weird, can you
help me" kinda mails.
any ideas for such a template?
JBoss Version:
OS:
DB/Driver:
CMP/BMP:
CMT/BMT:
Description:
jboss.xml:
jbosscmp.xml:
what else? (let's keep it simple)

|Hey,
|
|please always post jboss version, OS, DB
|Anyway you're using jboss 2.0 and that exception should be related to the
|fact that there is some problem in activating your beans.
|If you're using CMP, then this is very strange (unless you throw an
|exception in ejbActivate ;).
|If BMP, check that no unexpected exceptions (NPE and the like) are thrown
|from ejbActivate.
|
|Would be helpful if you could post client code and ejb code
