Read Dan's comment/answer.  The functionality is the ease of
configuration, etc.  For someone who has used Spring extensively, I
think its a huge loss not to be able to leverage it.

What are you talking about...this is clearly a classloader problem.  The
fact the client and the server are fighting over whose version of Spring
is the "right one" points its finger at a classloader issue.  The fact
the client has to set the hidden classes attribute on plans clearly
shows this is a classloader problem.  Am I missing or not seeing
something here?  If so, please point it out...perhaps I'm simply not
getting it.  Clashing versions is about as classloader related as it gets.

CXF can certainly be used in Tomcat.  Tomcat doesn't distribute it, but
it certainly can be used with that web container.  It appears the only
project who has this problem is Geronimo :-/

Well...lets agree to disagree.  The bottom line is we are castrating
other projects because we have messed up classloaders.  That, IMNSHO,
has nothing to do with apples-to-apples comparison and we are creating a
treatment to the problem rather than a panacea.

Do as you may, but call my issue with how we are handling this a
dissenting voice.  I am not in agreement with this action.
