RE: Thread question

Is this efficient to do?

Define "efficient." From a machine performance point of view, sure. The
sleeping thread won't take any machine resources so it's "efficient."
However, it's probably not how I'd do it. 

Don't forget you're still on an iSeries. Why not simply add something to
the job scheduler to run a job once a day to look for expiry dates? The
job could be either a "simple" RPG program or a java application. Why
make it a web application? If you need it to be a "Web" application I'd
still use the job scheduler and just use something like Brad's GetURI to
kick off the web page needed to invoke the process. What's starting the
sleeping thread? What restarts it on application start?
