Subject Re: My parameters are lost when storing them in HttpSession using Servlet
Date Fri, 14 Jul 2000 13:43:08 GMT
My form is written using Macromedia Shockwave flash, and I've discovered that the problem lies
with Flash, and not my servlet. I've changed my form to a normal HTML form and everything
works ok.

Thanks for replying anyway.

  If cookies are not supported, you should tried encoding your URLs with the encodeURL() method
of the HttpServletResponse interface.

  I hope this helps.

    I have a servlet which verifies user login information in a database. If the user is allowed
to login I add some information to the session object and redirect the user to a start page:

    public void doGet (HttpServletRequest req, HttpServletResponse res)
               throws ServletException, IOException
        {
    ..
    ..
      HttpSession session = req.getSession(true);
      session.setAttribute("loggedIn",  new String("true"));
      session.setAttribute("permission",  new Integer(iPermission));
      res.sendRedirect("index.jsp"); 

    ..
    ..
    }

    My problem is that when I try and access this session information in my "index.jsp" page,
all values are null.

    <%@ page errorPage = "Error.jsp" import = "java.util.*, javax.servlet.http.*, javax.servlet.*"
%>
    <HTML>
    <HEAD>
    <TITLE>KULIE</TITLE>
    </HEAD>
    ..
    <%=session.getAttribute("permission")%>
    <%=session.getAttribute("loggedIn")%>

    ..
    </HTML>

    I have no idea what the problem is, and have stripped my code right down to the bare bones
to see if I am making any stupid mistake. 

    Also, I have tested the following with  2 jsp pages, where 1 jsp page stores data in the
session, then redirects to another page where the data is printed. The files are as follows:

    v.jsp

    <%session.setAttribute("andy", new String ("HELLO!"));%>
    <% response.sendRedirect ("w.jsp");%>

    w.jsp

    <HTML>
    <BODY>
    <H1>
    <%=session.getAttribute("andy")%>
    </H1>
    </BODY>
    </HTML>

    This works fine, so my problem only seems related to servlets. 

    Has anyone any idea on what could possible be causing the problem?

    Thanks,

    Andy Shiels
