Catching a session timeout event
Hello,
I would like to somehow catch the event when a user's session times-out. How
can I do this?

Also set the
login.action=
logout.action=
properties in your TR.props file, as this tells the Turbine Servlet to do
some things to the Session. Search the Turbine.java for "logout" to see
more about what I mean.

Put your code in the doPerform method of MyLogoutUser.

I think Bill missed that. Call it if you're using the security service
in Turbine.

I prefer redirecting. :)
data.setRedirectURI(link.setPage("Logout.vm").toString());
data.setStatusCode(302);

Sorry about the stupid questions but I am new to all of this...
Would I be able to send the user to a different page in the site using this
code? That is, by adding code into the killoff() method?
Also, I notice that you do not call the super.doPerform() of the LogoutUser
class in the doPerform() of the MyLogoutUser class, why is this?
Also, at the end of the doPerform() in the LogoutUser, would I be able to
redirect the user to a different page in the site? I have tried to do this
with data.setScreen() before but I didn't have much luck.

I do it with 3 classes. One to override LoginUser, one to override
LogoutUser, and a timeout event catcher.
To wit:
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionBindingListener;
import javax.servlet.http.HttpSessionBindingEvent;
public class SessionTimeout implements HttpSessionBindingListener {
boolean alive = true;
public SessionTimeout() {
}
public void invalidate() { alive = false; }
public void valueBound(HttpSessionBindingEvent e) {
}
public void valueUnbound(HttpSessionBindingEvent e) {
killOff();
}
protected void finalize() throws Throwable {
super.finalize();
killOff();
}
private void killOff() {
if (alive) {
alive = false;
// Do what you need at timeout here
}
}
}
Here's how I use it in my Login and Logout classes:
public class MyLoginUser extends LoginUser {
public MyLoginUser() {
super();
}
public void doPerform(RunData data) throws java.lang.Exception {
super.doPerform(data);
HttpSession sesn = data.getSession();
SessionTimeout sto = new SessionTimeout();
sesn.setAttribute("timeout", sto);
}
}
public class MyLogoutUser extends LogoutUser {
public MyLogoutUser() {
super();
}
public void doPerform(RunData data) throws java.lang.Exception {
HttpSession sesn = data.getSession();
SessionTimeout sto = (SessionTimeout)sesn.getAttribute("timeout");
if (sto != null)
sto.invalidate();
}
}

Logout user
Posted by Ilan Azbel <il...@mdio.net>.
Hello,
I currently have a link on a webpage that calls the Logout action. This
action does not perform enough functionality in for my system; when the user
decides to logout, I want the user to be sent to a predefined page, not the
home page - what is the easiest way of doing this?
