 List login =sessionbean.login(name,password);        
         int t=login.size();       
         if(t==0)
         {
            response.getWriter().write("Wrong Username Or Password");
         }
         else
         {
             HttpSession session=request.getSession(true);
             session.setAttribute("currentSessionUser", name);
                  
            response.getWriter().write("Welcome");
