Same way you would create multiple threads -- just do it once :).
Actually, the J2EE standards say threads should not be created in servlets, though no servlet containers enforce this restriction. It's still a bad idea, though, because it can easily lead to orphaned threads that will eventually bring your server down. Instead if you want to perform tasks asynchronously, you should use Java Messaging Service (JMS).
