SingleThreadModel Interface

Hi

I know that servlet is multithreaded by default.By using singlethreadmodel interface does its multithreading capabilities are restricted?to what extent?
also can anyone tell me when we use singlethread model interface?i heard that this is to be deprecated soon?

Thanks

If your servlet implements SingleThreadModel, the servlet engine will ensure that a given instance only handles one request at a time.
In my opinion, SingleThreadModel was created early in the development of the servlet API as a crutch for people having a hard time making the transistion from desktop single user applications to servlets. I know of no valid excuse for using it these days.

It has been deprecated in the Servlet 2.4 spec (part of J2EE 1.4) without replacement. Which begs the question: if it was a superfluous, bad idea for servlets, what makes it a good idea for stateless EJBs?
