When you are forwarding to another servlet Are you specifying any method??
The answer is NO. So the default Method GET is taken & so if you are
overriding the doGet method it runs & when you override the doPost only it
does not.

Well when a Servlet is created by the Servlet Engine it initializes it &
then when a request comes in it passes it the requisite information like
request & response objects & forgets about it. Now within the Servlet
whatever you do the forward method or the Servlet Engine has no way to
recover the Request & Response Objects per servlet since they are created
per invocation. So you have to pass it.
