Quoting Jaliya Ekanayake <[EMAIL PROTECTED]>:
This is how they work now. Sandesha Sender is the last to run in the
handler
chain and it acts as a transport to axis engine.So client side has no
problem in the current configuration except that Sandesha needs to find a
way to ignore the wsdd file in the classpath, which is doable.
so once we figure this out there shouldn't be a problem on the client
side.

Currently any service specific handler will be invoked before the
RMProvider. RMProvider is the last component in the handler chain.
However RMProvider uses a threads to invoke the service so the initial
thread's context will not be visible to the service.
Just to be certain, so you are saying that the handlers run on one thread
and
the service is invoked on a different thread? Can we not have handlers
(all
handlers except RM) and the service on the same thread-- without lot of
trouble
as things are? We may be able to fix the problem with kandula but
even security I think associates certain parameters with threads, so the
same
problem might arise again in a different context under this arrangement.
