what is the advantage of using the SingleThreadModel interface rather than using the synchronized keyword before the service method.

Advance Thanx.

If your servlet implements the SingleThreadModel interface, servlet container may create several instances of the servlet to process different requests.If you synchronize the service method, all the requests will be processed one by one from a single instance of the servlet.

If your design requires either of those techniques, you need to redesign your application to properly make use of the servlet API. In my opinion, SingleThreadModel was a mistake in the first place - it is expected to be deprecated in the near future.
