      Hi,
      I am using RequestDispatcher to forward data from servlet to JSP.

      try{
 HttpSession session=request.getSession(true);
 session.setAttribute("LoginMessage",loginMessage);
 RequestDispatcher rd=request.getRequestDispatcher("../LoginMessage.jsp");
 rd.forward(request,response);
 }catch(Exception e){
 System.out.println("error2 in doGet "+e);
 e.printStackTrace();
 out.println("error2 in doGet");


      I am working in JBoss 3.2.1, When I run the servlet in browser I get this error: 
      21:02:02,013 INFO [STDOUT] error2 in doGet java.lang.NullPointerException
