Good book on threading as relates to Servlets

Could anyone recommend one ?

And also could you tell me if books/tutorials that use examples of threading such as:

Thread thread1 = new Thread();
thread1.start();

are useful to people who program only in servlets ? I ask as I have never used the Thread class explicitly in my code and don't want to put lots of effort into understanding threading in this situation if it's examples do not trabsfer well to Servlet programming.

Thanks.

They aren't overly useful in servlets as they tend to rarely require >1 thread due to the fact that they simply process a request and return a result, and generally do not do any background processing.

An example where threads could be used in a servlet is where you need to perform a lengthy request in a servlet, so the servlet request would initate a new thread to perform the process and return a response to the user saying the task was 'in progress'.

I was always unsure if that tutorial would be useful to me, and it looked huge, but having thought about your answer I found a link in the Web services tutorial at:

http://java.sun.com/webservices/docs/ea1/tutorial/doc/Servlets5.html

that also recommends I should read it. So I shall !

Thanks for your help.
