Hello
I want to know that in which order the registere listeners will be notified. Means suppose i have registered ServletContextListener,ServletRequestListener,HttpSessionListener then in which order they will be called by container?

They are called when the appropriate event occurs. ServletContextListener reacts to changes in the servlet context og the applciation (e.g. Servlet initialisation). ServletRequestListener reacts to requests. HttpSessionListener reacts to session creation/deletion events.

As already mentioned the listener is called when the appropriate event occurs. So, obviously a servlet context event listener will be called before a servlet request or session event listeners.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
