Hi John,

You open yourself to a whole world of pain once you introduce concurrency.  If you can avoid it then you should. 

If there is an unavoidable need for concurrency then you might want to consider using Camel.  Then you are managing queues rather than threads, which is much easier.

Hi all,

I have heard many times "do not create threads in a web app", since the container should manage them. However, the more modern APIs such as ExectorService appear to be used in web apps by some people. Can you use such java.util.concurrent classes in a wep app that requires multi-threading (e.g. due to high load), or do you forward data to a stand alone app that deals with the multi-threading? I can't find a definite answer on the internet.
