hfsj says,

flush( ) commits the response.
so we cant call anything on the response ( methods to do sendRedirect( ) and adding/setting things in the response ), once we say flush( ).

my query is if, after the response is commited, and i say
out.println( ), where out is a PrintWriter, what will happen ?

If the response is commited you cant forward to any other servlet. You have to choose. Either commit the response and handle the content yourself or forward to another servlet/JSP without commiting the response

It will give you an IllegalStateException as it is given in the specs.
