There is no concept of a browser closing. Since all http sessions are stateless,
then each time a page is requested then when the browser finishes loading the
page or not, it is the end of the http session.
Unless you check with the server how much of the content has been sent there
is no real way to catch this.
If what you really want is to know if the user is no longer browsing your site
then the timeout of a session can be captured with with the interface
HttpSessionBindingListener, which get called when the session times
out (so, say after 30 minutes of inactivity)
An alternative (but more hassle, and a pain for the user) is to either use the
<body onunload=""> or to write an applet that sends a UDP packet when the
close method is called (although you then have a delay when the page load
and the UPD packet may not get through) ...
