No. The one you are talking about is the case of Single Thread Model.
In general, container creates different thread for each request and all threads execute at the same time.

Servlet and JSP is not Thread Safe By Dafeult.
If You want to make Servlet Thread Safe, you need to implement SingleThreadModel interface.But this is deprecated now. It not advisable to use this.
If you want make JSP thread safe, make page attribute isThreadSafe="true". but servlet class generated from JSP implements SingleThreadModel interface. So, this too is not advisable to do.

This is too complex a question to handle in a simple forum response. Go read a servlet tutorial, then browse past discussions. You are not the first person to ask this question and there is no need for us to repeat the many discussions that have resulted.
