Hi,
Whenever we do respose.sendRedirect() it will be a new request altogather
for the server. We will not be able to fetch the request parameters which we
post to the target. I would like to give an example.
<form name="test" action="/myhost/cash/sample.jsp" metho
d="post" target="secpopup" >
<input type="hidden" name="param1" value="122123">
<input type="submit"
</form>
If I submit this form from /myhost/sim/sample2.jsp I am able to access the
/myhost/cash/sample.jsp and able to access the request parameters.
But if I post the following form
<form name="test" action="/myhost/cash/sample.event" metho
d="post" target="secpopup" >
<input type="hidden" name="param1" value="122123">
<input type="submit"
</form>
It goes to servlet of /myhost/sim application tries to access
/myhost/sim/myhost/cash/sample.event which does not exist. I had already
used the workaround/solution you described in your previous mail, but I
think there may be another solution to it.
I am not very sure whether JSP engine interacts in the same way as my
servlet does.
Thanks,
-ShriKant
