Hi,
According to the servlet 2.2 spec section 3.3.3.1 on Multithreading issues:
"During the course of servicing requests from clients, a servlet container
may send multiple requests from multiple clients through the service method
of the servlet at any one time. This means that the Developer must take care
to make sure that the servlet is properly programmed for concurrency"
It means that the servlet will be multithreaded, but you will have to take
care of concurrency.
Further the spec says that "...........It is strongly recommended that
developers not synchronize the service method or any of the HttpServlet
service methods such as doGet, doPost, etc."
You can synchronize your servlet methods, but the whole app becomes slow,
since the calls have to be queued. Better to use the SingleThreadModel
instead.
Hope this helps,
Anil.
