Axis webservice leaving sessions open under websphere

[Schwartz, Karen]

We are running webservices using Axis 1.4 under Websphere 6.1. We are 
experiencing a problem that each time the webservice is invoked an http servlet 
session is opened under websphere and is not invalidated when the webservice 
call completes. Is there some way to prevent the session from being generated? 
or some way to get AxisServlet to invalidate the session when the webservice 
call completes.
