[Htmlunit-user] Cookie problem

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi all
I am a new to htmlunit. I find it very good.
I seem to have a problem with it though. My app is
structured in such a way that A.jsp calls B.jsp which
in turn calls C.jsp. This sort of redirection is
achieved in the client side (rather than the server
side). There is a javascript code which submits the
form as soon as it is loaded and that's how
redirection is achieved.

I am able to go from A.jsp to B.jsp. But the
redirection from B.jsp to C.jsp does not work because
of the following javascript code in the output of
B.jsp

var cookie = document.cookie

The above code results in the exception noted below:
(I have gone though the faq which suggests to check
the commons-httpclient.jar and I have ver 2.0.1 which
is faily new I guess.)

Any ideas?
