why not just use a respond.sendRedirect? that will behave as you like.
if(session.isNew()){
session.invalidate();
response.sendRedirect(response.encodeRedirectURL("/SS30/default.jsp")) ;

I implemented the following one with the setMaxInactiveinterval(600) and the
rquest dispatcher to redirect the URL. But I have a small problem here.The
redirection does not change the URL in the browser. It remains the same. i.e
I have my redirection code in TestSesion.jsp(URL :
http://localhost:7001/TestSession.jsp). And it redirects to login.html. But
after it redirects the login.html page comes up but the URL is
still(http://localhost:7001/TestSession.jsp). Please let me know if I am
missing something here. The code in TestSession.jsp is very simple and as
follows..
<%
session = request.getSession(false);
if(session.getAttribute("id") == null)
{
RequestDispatcher dispatcher =
request.getRequestDispatcher("login.html");
if (dispatcher != null) {
dispatcher.forward(request, response);
}
}
else
System.out.println("The session is not null");
%>
Thanks.

Sorry, but I don't think Javascript has anything to do with it.
The amount of time for a session to timeout is specified in the server's
configuration. For the Tomcat container in server.xml:
<Context path="/examples" docBase="examples"
defaultSessionTimeOut="30" isWARExpanded="true"
isWARValidated="false" isInvokerEnabled="true"
isWorkDirPersistent="false"/>
In this case the session will time out after it has been idle for 30
minutes. If you change defaultSessionTimeOut to 15 it will be 15 minutes.
Then in your servlet/jsp you can do something like this:
// true specifies to create a session if one doesn't already exist for the
user
// you could also specify false and then test if session is null in the if
statement
// if you want the login page to create the session
HttpSession session = request.getSession(true);
// the session is new if the client doesn't know about it yet
if (session.isNew()) {
// use a RequestDispatcher to forward the request
// don't use sendRedirect to avoid another roundtrip to the client
and back
RequestDispatcher dispatcher =
request.getRequestDispatcher("/jsp/login.jsp");
// dispatcher may be null if the container can't find the file
specified
if (dispatcher != null) {
dispatcher.forward(request, response);
}
else {
// go to your error page
}
}
You can also specify the amount of time for a session to timeout
programmatically using the following:
HttpSession session = request.getSession(true);
// specify the amount of idle seconds until this session will timeout
session.setMaxInactiveInterval(15 * 60); // 15 minutes * 60 seconds

Subject: Session timeout
How can I timeout a session using JSPs ?? i.e if the User is initially logs
into my web site and then is idle for 15 minutes I want to timeout his
sesion .After the timeout, if the User clicks on anything on the existing
page I want to redirect him to the Login page of the application. Also if
he goes back in the browser (Using the Back button) I do not want to allow
him to do that. I am quite new to JSP and hence any help will be highly
appreciated.
Thanks in advance.
