Dear frien i am studing Head First Servlet JSP on page 196 It has been written that
"Synchronizing the service method would stop other threads from the same servlet from accessing the context attributes, but it don't do anything to stop a complitely diffrent servlet"
Okay i ma agree byt why it happen why synchronizing service method let other servlet execute the service method but but the servlet exist in same web can't execute the service method why?

Thanks and Regard
