How single threaded model works after implementation in class, basically architecture point of view.

The Single Thread Model is an interface which is used to indicate that only a single thread will execute the service( ) method of a servlet at a given time. It defines no constants and declares no methods. If a servlet implements this interface, the server has only two options. 1st, it can creat several instances of the servlet. 2nd, it can synchronized access to the servlet.
