Hi
Thanks Richard for putting this minimal Scala 2.9/2.10 example together
to demonstrate this "class loading problem".
I took a peek at it and found a way to get around the problem found with
the 2.10 build (see below), however I still have not found the direct
cause of the problem and hope that someone in the Geronimo community
could help narrow it down a bit more, It would be greatly appreciated (
David J ? ;) ).
To make the 2.10 build deploy and start correctly, as the Scala 2.9
build dose, I added the inverse-classloading [1] setting to the
deployment descriptor (for the Scala 2.10 build, its not needed when
building with Scala 2.9), this may however not be a ultimate solution in
all situations so if anyone have a better solution or a suggestion on
how to narrow it down pleas let us know.

Hello.
I've run into a WAR deployment problem that I'm hoping someone here
can help me understand and resolve.
I've put together a small web application (just a servlet filter)
which references Apache Commons Codec. This project uses Scala. When
build with Scala 2.9 it deploys to Geronimo and runs. When build with
Scala 2.10 it does not deploy. However, both versions happily deploy
and run under Tomcat 7.
The exception is:
ERROR [[/hello]] Exception starting filter MyFilter

I've put the project on github with details of steps to reproduce and
the full stack trace and WAR contents:

Any suggestions for how I can resolve this one?
Thanks
Richard
