Hello sir
i am really very much thankful to you
I have done the same as you have told me
It was really great.I was trying a lot to extend a servlet from a jsp.But can
we do this.i think we can do this.But the Problem was my servlet used to
execute fine but after that the control was not comming to the JSP.It use to
trow some exception at that time.
Then i tried as you told me,and it worked fine
but have you seen a JSP extending a servlet
Ok bye for now
