i'm developing an Intranet mailing system using JSP. I want use the userid throughout my session. For that, i'm using the implicit 'session' object in JSP, as shown below.. String usrname=request.getParameter("username"); if(session.isNew()) session.putValue("Username",usrname); I'm writing this code in a file, say login.jsp I want to use that 'usrname' throughout my session, until session is invalidated. In another file, say inbox.jsp i want to use that userid. For that i'm retrieving the value stored in the session as follows.. String userid=(String)session.getValue("Username"); out.println("<b>"+userid+"</b>"); But i'm getting a null value when I use the above statement. Instead I should get the userid that is entered by the user during login.... Why Am I getting a null value, where in I should get the username? Pls tell me where did I go wrong.. Reply asap.. Waiting for the help.. regds, Sandeep.

Did you create the session first by sending true to the constructor? Bosun

Is the file login.jsp the form where the user enters their userid? If so, I don't think the getParameter will return anything, because it is actually running before the user has input any value. I have my login setup like this. login.jsp - screen to capture login info, once they hit login button, I send them to menu.jsp menu.jsp - screen to getParamater from login.jsp and validate the user info. if they are not validated, I send them back to login.jsp. If they are validated, it then store the info in a session variable using the session.setAttribute. It should then be available until the session ends. Good luck! Jason.
