I have problem when i use EL for the below scenerio. Please help

<form id="newUserForm" action="registerServlet" method="post">
Email Address:<input type="text" name="email" value=""/>
<input type="submit" name="signUp" value="SIGN UP" />

.. code for checking if email already exists in db
..if yes, then
HttpSession session = request.getSession();
session.setAttribute("", e.getMessage());
request.getRequestDispatcher("JSPs/SignUp.jsp").forward(request, response);

when i submit the SignUp form , i am redirected to the same form but error message is not being displayed.

Please let me know if anything else has to added.

Thanks Bhanu, your solutions works.
If scope is not mentioned then, is it not that all the scopes(session,application,page,request) are searched for that particular variable? please correct me if i am wrong. As there were no other variables with the same name in any other scope, i used directly ${var}.I didnt get why it didnt work for me.

Because the scoped variable name contains dots. You must use the general reference operator ([]) rather than the dot shortcut operator.
