Thanks for your reply, actually I can not change the login servlet method, that is out of my control.
I still can not get these two things here, one is why my gwt application is trying to call UserService without any mapping for it in web.xml, I could see the logs like [WARN] 404 - POST /B/userinfo (127.0.0.1) 1411 bytes in Jetty console. Another thing is, order of execution, because call of userService is defined inside onResponseReceived() of login it should get called once login response is received. Thanks for the help.
