You first need to learn ethics to ask question on a forum. Never use as soon as possible phrase again.

Further, regarding your question, so there is no such thing that as Controller, however you can design a Stateless Session bean to behave like Controller.

So there actually *is* such a thing as a controller? :-)

A controller is a pattern that could occur in any one of the various architecture layers, but the most common one is probably the "C" in "MVC" than is often found in the front end of a web app. That's probably what you're asking about, since you posted in the Servlets forum. This article may bring about some clarity: http://www.javaranch.com/journal/200603/Journal200603.jsp#a5

Yeah I do agree that there is no such thing exists as Controller, but many a times Servlet is being used as controller and hence many newbies corelate two terms.

So if a servlet is serving as a controller, how is that not a controller? Your statement makes no sense.

Hello raviteja.

Controller is just a pattern name, I believe the controller is in charge of checking what the user is requesting.
