Ah, thank you; I will try this. If this is the problem, is this =
something
which might be fixed in upcoming versions of Jython, or is it an
undefeatable effect?=A0It seems a little constraining not being able to =
treat
jython-originiated servlet-classes the same as regular serlvets. (Or am =
I
misunderstanding something?)

Of course, I guess the procedings you advice here are probably how most
things should be done in a "proper" setting.

Thanks!
