I just tried your suggestion,
it doesn't work.
The page flow is:
RedirectAction -> RedirectHelpAction -> RedirectStep3Action
Here is the RedirectAction.java file:
import org.apache.commons.logging.LogFactory;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletConfig;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
/** @struts.action name="RedirectForm" path="/struts_redirect_portlet/input"
* attribute="redirectForm"
* scope="session"
* input="/portlet/struts_redirect_portlet/input.jsp"
*
* @struts.action-forward name="input"
path="/portlet/struts_redirect_portlet/input.jsp" redirect="false"
* @struts.action-forward name="help"
path="/portlet/struts_redirect_portlet/help.jsp" redirect="false"
*/
public class RedirectAction extends PortletAction {
public ActionForward execute(
ActionMapping mapping, ActionForm form,
HttpServletRequest req,
HttpServletResponse res)
throws Exception {
RedirectForm redirectForm = (RedirectForm) form;
String comment = redirectForm.getComment().trim();
if ( comment.length() > 0) {
return mapping.findForward("help");
}
return mapping.findForward("input");
}
public ActionForward render(
ActionMapping mapping, ActionForm form,
PortletConfig config,
RenderRequest req, RenderResponse res)
throws Exception {
return mapping.findForward("input");
}
}
Here is the RedirectHelpAction.java file:
import javax.servlet.http.HttpServletResponse;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletConfig;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
/***

path="/portlet/struts_redirect_portlet/help.jsp" redirect="false"
* @struts.action-forward name="step3"
path="/portlet/struts_redirect_portlet/step3.jsp" redirect="false"
*/
public class RedirectHelpAction extends PortletAction {
public ActionForward execute(
ActionMapping mapping, ActionForm form,
HttpServletRequest req,
HttpServletResponse res)
throws Exception {
RedirectHelpForm redirectHelpForm = (RedirectHelpForm) form;
req.getSession().setAttribute("RedirectHelpForm",
redirectHelpForm);
String name = redirectHelpForm.getName().trim();
if ( name.length() > 0) {
return mapping.findForward("step3");
}
return mapping.findForward("help");
}
public ActionForward render(
ActionMapping mapping, ActionForm form,
PortletConfig config,
RenderRequest req, RenderResponse res)
throws Exception {
return mapping.findForward("help");
}
}
