The jaws client maybe takes 100ms to fire up. So it's not terrible slow
but the overall website is noticeably faster when caching it. All of the
resources (wsdls, xsds) are local but there's a quite a few of them.
Caching this object does not work as a session attribute.
HttpServletRequest#setAttribute("mykey", clientObjectHere);
followed by
HttpServletRequest#getAttribute("mykey") == null on subsequent http
requests.
ServletContext#setAttribute and getAttribute does work however it is not
viable in my situation

Can you define "doesn't work"?

So, placing the client into the application via
ServletContex.setAttribute("jaxclient", client) works?

Tomcat itself has no specific requirement for session attributes to be
Serializable, unless you want your sessions to be "distributable" (as
in a cluster). If you want to improve performance, using clustering
isn't a great strategy, though.
Tomcat won't fail immediately when adding a non-serializable object to
the session. Instead, it will fail/log-error at the end of the
request-processing when the changes to the session are propagated to
the other node(s) in the cluster. Thus, your local session *should*
continue to work.
I'm curious about what takes so long when creating the JAXWS client.
