I want to write Thread Poolusing Java for some repititve task which is controlled through Job Scheduler.Job Scheduler will run after interval of 2 minutes.Can you please provide me few guidelines regarding how to write thread pool in Java.
My application will be deployed on Application Server and I am using JDK 1.4. I know there is a java.util.concurrent.Executors class which can be used for this. However, It's available in JDK 1.5 & not in 1.4
You can use the java.util.concurrent backport to get most of the concurrent functionality in earlier JDK versions. There are also other thread pool implementations out there, or you could write your own, but unless you're doing this as a learning exercise, using java.util.concurrent is probably easiest.

Creating a ThreadPool logically vary from people to people.The easiest of creating a thread pool is to use java data structure (Hashtable,Hashmap prefferably) and take boolean variable ,just to identify(whether this thread in use or not).This is somewhat similar to connection pool maintain by the webserver/Application server.
Hope above hint will be helpful for you in someway.
