In your servlet, you must use the passed in request object to obtain 'the' session, not just any session. This might be the problem if you're not doing it.
Session ses = request.getSession(); ses.setAttribute("hello", "hello"); . . . Then you get the RequestDispatcher and forward RequestDispatcher rd = getRequestDispatcher("/somePage.jsp"); rd.forward(request, response); . . inside somePage.jsp, you should be able to access "hello" like you already know how to do.

i called ServletContext.getRequestDispatcher(**). but if i give the whole absolute path of the jsp page it is returning null. like RequestDispatcher rd = ServletContext.getRequestDispatcher("http://localhost:7001/checkmail.jsp") here rd will be null. but if i give relative path like "/checkmail.jsp" i will get the rd object but when i call rd.forward(**,**) the jsp page is not coming i used the HttpServletRequest.getRequestDispatcher() also. i am using Weblogic 6.0 application server. i cannot give relative path like "/checkmail.jsp" becoz the control will be returned from a servlet ie "http://localhost:7001/examplesWebApp/MainServlet" and it is taking "http://localhost:7001/examplesWebApp/checkmail.jsp" so i am not able to view the jsp page. the MainServlet is a FrontController for the application and all the html/jsp request will go through this servlet. so according to the data got from the backend i should send the objects to the jsp page as session attributes.
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
