According to the J2EE spec there is no guarantee that a .forward request or
an EJB call will execute on the same thread (even if the EJB call lands in
the same process).  This seems to render MDC and NDC much less useful
because these constructs rely on the thread.  Changing it pulls the rug out
from under the mechanism.

Am I missing something?  Is there a "standard" way Log4j users should handle
MDC to ensure the context persists across .forward and EJB calls (when in
the same process)?

I reviewed the Complete Manual and couldn't find anything related to this
question.

Thanks for your time.

Mike
