I'm using CVS HEAD :-)

Cool, thanks. It looks like hermes is definitely loading before the SAAJ
jars.

Everything works fine when I run the client and server in separate JVMs
and that's what I've been doing while tesing to eliminate any
classloading issues which always come as part of integration but the
time has come to integrate them into the same JVM space. I'll read the
thread Ronald pointed out as well and try to get you more information.

Has anyone by chance completely isolated the set of classes the client
uses from those in the WAR? That's what I was going to attempt next.
Basically make a little world for the client to run in.

In short, man creates for himself a new religion of a rational
