I've mainly worked in BEA WebLogic before and from colleagues and other sources I have heard it is not recommended (and sometimes not allowed, some even said) to create threads in your application. Indeed, when the application went live in a multi-server clustered environment, we got very inconsistent results because of the threads, so we had to remove them.
Question is, how safe is it to create threads in a Tomcat web-app? I would assume "worker" threads are ok, i.e. threads you create to do a specific task and then it terminates. When you are guaranteed the thread will terminate either because of an error or because the assigned task has been completed. But what about "monitor" threads, i.e. threads that does a Thread.sleep(x) for an hour, check some condition and goes back to sleep... some mechanism you implement to e.g. do a task on a hourly/daily/weekly base. You'd create the thread (and keep a handle to it) in either an InitServlet.init() and then Thread.interrupt() in the InitServlet.destroy(), or you can do it in an ApplicationListener (something like that) class which I think you can define in the web.xml. How else can you implement that (monitoring) in Tomcat? __________________________________ Do you Yahoo!? Yahoo!
