Session checking with Struts 2

[Rusty Enisin]

I am using and AJAX call to determine if the user's session has timed out. I am using Struts 2. I tried implementing ServletRequestAware and then getting the session from that like this:

 
...
 
public class LiveSessionCheck implements ServletRequestAware {
 
private HttpServletRequest request;

public String execute() throws Exception {
 
HttpSession session = request.getSession(false);

if ( session != null ) {
return "success"; 
}
else {
return = "failure";
}
}
 
}

But it seems that the session is getting created by struts because the session is always not null (Even though I know the session was killed).

Any ideas on how to do this?

I've found that getSession(true) is not a good way to check for a valid session in Struts 1 or Struts 2. The method I've found most effective is to put some object in the session when the user logs on. Then check for the existence of that object. If it's not there, you know the session has expired.

Thank you. That makes sense. I will do it that way.
