Question

I want to redirect the user into last accessed page after session expire and i prompt user to login again. In that i passed last page url into one parameter and invoke a seesioerror action for validate the user.

I have this code snippet :

   <script type="text/javascript">
        var currentURL = window.location.href;

    </script>
     <%

        String url= "<script>document.writeln(currentURL);</script>";

        Object obj = session.getAttribute("user");
        if (obj == null) {
            response.sendRedirect(request.getContextPath() + "/SessionError?backurl=" + url);
        }

     %>

Now my problem is whenever I print the Java String varaible url using <% out.print("URL" + url);%> it correctly print the page URL.

But If pass it on this line response.sendRedirect(request.getContextPath() + "/SessionError?backurl=" + url); inside the snippet. It only pass <script>document.writeln(currentURL);</script> not the current page url like http://www.mysite.com/home. Please help me to get rid of this problem.

You should be using

request.getAttribute("javax.servlet.forward.request_uri")

And please don’t mix sciplets and Javascript code. Its a mess.
