I used resin in my college days as an application server hosting multiple web applications including java servlet-based ones (like jsp/jstl).It was very fast back then with good stability too! it had some problems like memory leaks etc but they were resolved later by Sun's patches or releases. i think its still available atleast till now?I dont know about other features though. But at least you can try this if your requirements are satisfied only with performance. I needed a powerful appserver which could host many apps/servlets concurrently without any hiccups!! so thats what resins did best.i would say go ahead!! just give it a shot. it will not disappoint you. As mentioned earlier there might be few bugs reported even after sun released their updates.but overall experience should be great.you may have issues here and there while setting up with dependencies.But nothing serious.
