This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
If our method body is blank we dont need to throw none right?
Also what is this processRequest () in servlet when we use tomcat? its not there in Servlet specification right? because it says service() will called either doGet() or doPost() method not processRequest() ?
While overriding we may throw fewer or narrower checked exceptions or any unchecked exceptions.
So I think it is not necessary to declare that doGet() or doPost() throws ServletException and IOException.
