Subject Re: Sticky servlet
Date Tue, 18 Sep 2007 20:11:49 GMT
In j2ee specs, there is no provision for unloading an unused servlet. 
Once a servlet has been tarted (load-on-startup or triggered by user 
query), i never get unloaded, unless webapp gets unloaded, which occurs 
at shutdown or during a redeploy (administrative task)
