Isn't that non-standard?
I mean, Geronimo should be prefering the libs in the WAR over its own
libs. I thought that was part of the spec for webapps.

I've been having the same trouble myself, and its contrary to what I
expect having used a veriety of other app servers. Geronimo should not
be causing my application to blow up because of library conflicts.

I do think its ability to share libs easily is good, but I think the
default should be to isolate the webapp and allow sharing to be turned
on via the geronimo config xml file.

Does anyone know why Geronimo is so loose with its classloaders? Was
this a design choice or an artifact of some other issue?

If it was a design choice, I would *really* like to see the
justification for it... and if an artifact, it needs to be corrected
