Better way to check user session

[Erap Estrada]

Hello guys, I just wonder if there's a better way to check if the user is logged in and has a valid session.

Normally, I do this on my Action class:

Account account = (Account)request.getSession().getAttribute("user");
if(account != null){
 
// process stuff and forward user to right page
}else{
//forward user to log-in page and tell them their session has expired.
}

Now, I wonder if there's a way to do it dynamically like how Struts do it in form validation. Just set it on xml file and good to go.

Thank you in advance.
