Hi,

I have a simple change password form that works something like this:

(in home/changePassword.jsp)
<%
RequestDispatcher rd = request.getRequestDispatcher("/servlet/AuthenticatedUser");
rd.include(request, response); // sets the 'user' request attribute
User user = (User) request.getAttribute("user"); // User is defined somewhere else
%>
...
<h2>Hello, <%= user.getName() %></h2>
...

...


(in ChangePassword.java)

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
// process request
// if (ok) change password
RequestDispatcher rd = req.getRequestDispatcher("/home/changePassword.jsp");
rd.forward(req, resp);
}

The problem is that the variable user is null after POSTing to this servlet. Why does the request attribute get set correctly when I GET /home/changePassword.jsp, but not when I use RequestDispatcher.forward() from the ChangePassword servlet?

Thanks,
