The following is only an idea which I have not tried it. After the form is submitted and data validated, throws a org.apache.tapestry.RedirectException to go to your custom service. eg : throw new RedirectException(url to your service);
http://tapestry.apache.org/tapestry4/tapestry/apidocs/index.html You can either pass the form data in the url of your service or pass a 'key' for the form data and use the key to retrieve the data in your service's service method.
