Optional Valve to detect long-running web requests.

If a web teir request takes too long, a warning message is logged. A JBoss customer requests implementation of this feature which is currently included in WebSphere.

This feature can be accomplished with a simple Valve. During the invoke method of the Valve, a Timer is set. If the Timer expires before the request is finished, a warning message is logged.

The Valve pseudo code might go something like this:

public void invoke(Request req, Response res)

{ set timer getNext().invoke(req, res); turn off timer }
