Every thing looks fine to me. Is this the actual struts-config.xml you are
trying to use - because I did notice your "/user/update" has re-direct in
the "Success" forward. Obviously you say the problem is with the
"/user/setUp" action but I ask because a re-direct would cause the kind of
behaviour you describe.
