I am surprised someone hasn't already boggled at this, so I guess I'll step up.
Unless you are restricted to using jws2.0 by a business decision,
you should *not* be using this for production systems. The codebase of this technology has not been updated since sometimes around 2000, and besides that it is 2 minor point releases behind the servlet spec.
Tomcat 4.x would be far better, even though some might suggest it is not 'production quality'.
