How do you launch multiple threads from within Java EE?

Question

I need to scale calls into Tomcat and it\'s been suggested to launch threads internally. Has anyone needed to do this and, if so, what solutions did they come up with?

Answer 1

Your question is a bit vague. Tomcat itself already uses a thread pool to service HTTP requests. You can increase the number of threads through Tomcat configuration - look to the Tomcat wiki for info on this.

If you mean that in your code you want to launch threads, then I advise perusing the java.util.concurrent API introduced in Java 5. Also read "Java Concurrency in Practice", which is the text on this subject.
