getRequestURL on a JSP forwarded from Servlet

[M Rama]

I have the following Servlet get method:

 
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

RequestDispatcher view = this.getServletContext().getRequestDispatcher("/main.jsp");
view.forward(req,resp);

}
 

in the main.jsp i do the following:

getRequestURL()=<%=request.getRequestURL()%><br>

in one websphere server i get the servlet name ( http://hostname/App/TRO.do ) and in the other one the jsp name ( http://hostname/App/main.jsp )printed on the page. The url is similar in both which is ( http://hostname/App/TRO.do )

i deployed then same EAR to both the servers. why is this behaving this way?

Thanks
