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.
