Answer / srilatha

Forward():

In ServletRequestDispatcher ,By using forward() method,we
can forward a request to a another resource(i.e
servlets,jsp,html....),at finally we can see only called
resource output(i.e second resource output,i.e response)
For exm. we have two servlets,(servlet1 and servlet2) we are
forwarding request from servlet1 to servlet2, in this case
we can see only servlet2 output(i.e response for the
request).
in forward()it will take only servlet1 output.
(ex: in servlet we a\are having some name like srinu with
background color blue, it will take only the name not the
color)

include():

By using include() method of RequestDispatcher we
can forward a request from servlet1 to servlet2 ,in this

in include()it will include the servlet1 page and
forwarding to the servlet2)
