How to redirect on login page after logout

Question

I want to when click on log out tab then redirect on login page after logout. This is not go on login page.

Home.jsp

<ul><li><a href="http://pushkalit.in/logout.jsp"> Logout</a></li></ul>

logout.jsp

<% try {

    if(session.getAttribute("Username") != null) {
        response.setHeader("Cache-Control","no-cache");
        response.setHeader("Cache-Control","no-store");
        response.setHeader("Pragma","no-cache");
        response.setDateHeader ("Expires", 0);
        session.invalidate();
        response.sendRedirect("http://pushkalit.in/hrlogin.jsp");
    }
    else {}
}
catch(Exception ex) {
    out.print(ex);
}
%>

Whenever the page is rendered,user will get his session invalidated irrespective of his clicking the Logout hyper link — Kumar Abhinav, Mar 24 '14 at 08:17

i think it would be easier if you just put the logout login inside servlet instead of an jsp. And don't forget to do a

session.invalidate()

EDIT (further detail): something like this :

package com.my.package;

public class LogoutServlet extends HttpServlet {
  protected void doGet(HttpServletRequest request,
    HttpServletResponse response) throws ServletException, IOException {

    response.setHeader("Cache-Control", "no-cache, no-store");
    response.setHeader("Pragma", "no-cache");
    request.getSession().invalidate();
    response.sendRedirect(request.getContextPath() + "/login.jsp");
  }
}

In your servlet.xml (you could also do it with an annotation) configure it like this:

<servlet>
    <servlet-name>logoutServlet</servlet-name>
    <servlet-class>com.my.package.LogoutServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>logoutServlet</servlet-name>
    <url-pattern>/logout</url-pattern>
</servlet-mapping>

And then finally your link goes to:

<a href="http://pushkalit.in/yourapplication/logout">Logout</a>

An error occurred at line: 13 in the jsp file: /hrlogout.jsp void is an invalid type for the variable doGet – Deepak Singh Mar 24 '14 at 08:28
what i'm suggsting you is to write a servlet with the code provided and not to copy it inside your existing hrlogout.jsp – fGo Mar 24 '14 at 08:35
public class LogoutServlet extends HttpServlet{ doGet(...) {...} } – fGo Mar 24 '14 at 08:36

URL mapping in anchor tag seems to be wrong.

It is linked to logout.jsp but you have the redirect code in Hrlogout.jsp.

Change:

<a href="http://pushkalit.in/logout.jsp"> Logout</a>

To:

<a href="http://pushkalit.in/Hrlogout.jsp"> Logout</a>
