It will sound like a scratched vinil, but I believe that forwarding from search page to result page is not the right thing to do, because whenever you refresh result page, you run the search query again. So, it should be a redirect. I see the following choices: * pass search results in request * pass search results in session * pass results in session, and navigational info like current page, first line on page, last line on page, etc. in request. Result page for search form does not have to be stateful. What do you expect, if you navigate to result page, typing its location in address bar? If it does not have to keep previous search results, than as long as you able to fit everything into request, it probably would be the best. If you decide to use redirect and request, action forms or request object will not help you. You would have to append it manually to URL, since you cannot simply stick it into request object, it is destroyed and recreated with each request. P.S. If you have simple string results, maybe you can use some kind of hack, sticking results into session under error message key, so after the results accessed, they are removed by RequestProcessor automatically? Did not give this a lot of thought. But this idea seems promising: to define types/instances/keys of ojects, which would be removed automatically after accessed.
