The problem is that forwards are done using redirect. This creates a new request which will not contain the request parameters sent with the form. In Velocity, you can add request parameters to the forward URL by using addQueryData(), but I don't know if this is possible in JSP, and anyway would not be much help to you because the parameters are part of the form. So you probably need to do the forward in Java, using the ForwardService. There you can add the request parameters from the form, or put them in the session and collect them in the second portlet.
