javax.servlet
Interface SingleThreadModel
public interface SingleThreadModel
Ensures that servlets handle
only one request at a time. This interface has no methods.
If a servlet implements this interface, you are
guaranteed
that no two threads will execute concurrently in the
servlet's
service
method. The servlet container
can make this guarantee by synchronizing access to a single
instance of the servlet, or by maintaining a pool of servlet
instances and dispatching each new request to a free servlet.
If a servlet implements this interface, the servlet will
be thread safe. However, this interface does not prevent
synchronization problems that result from servlets accessing shared
resources such as static class variables or classes outside
the scope of the servlet.
