page.xml redirect with parameter

[mconroy]

I am attempting to redirect to a page on another web application. The following code works correct, but the parameters are not passed. I have verified that the parameters are set by modifying the url attribute to include the ?proj=#{project.number} at which point the receiving site gets the parameter. Can parameters be specified using a page.xml in this fashion?


<navigation from-action="#{project.open}">
          <rule if-outcome="true">
               <redirect url="http://someurl.com">
                    <param name="proj" value="#{project.number}" />
                    
               </redirect>
               <end-conversation/>
          </rule>
     </navigation>


I am using 2.2.0GA.

Thanks All!

Can't be done. I'm guessing that the params are for forwarding purposes only...

Redirect

    * a redirect is a two step process, where the web application instructs the browser to fetch a second URL, which differs from the original
    * a browser reload of the second URL will not repeat the original request, but will rather fetch the second URL
    * redirect is marginally slower than a forward, since it requires two browser requests, not one
    * objects placed in the original request scope are not available to the second request

Are you calling #{project.open} from your JSF page within a link or a button ?

Then pass the parameter within those components.

Example:

<s:link action="#{project.open}" ...>
   <f:param name="proj" value="#{project.number}"/>
</s:link>

Thanks for the response Serkan!

Unfortunately I was trying to do something far more quirky than that. I was attempting to do a web redirect to another context and post the data. This is probably my failed attempt, but the project will be a authentication front end for several applications. The new application will collect authentication info and then forward some type of security token on. I thought about using a get request, but I would like to avoid having encrypted credentials in the url.

I found an interesting way of doing this by creating a custom servlet to intercept the web request and insert the parameters in the request attributes, but that eventually fails due to class loader security restrictions in the receiving context. I am attempting to figure that problem out now.

Here is the servlet code if anyone is interested. If anyone has a better idea feel free to throw it out here.

package org.safmt.bigbro;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.jboss.seam.contexts.Contexts;

import org.safmt.bigbro.model.AuthUser;

public final class AuthForwardServlet extends HttpServlet {
        public void doGet(HttpServletRequest request, HttpServletResponse response) {
                HttpServletRequest req = (HttpServletRequest) request;
                req.setAttribute("user", Contexts.getConversationContext().get("auser")));

                try {
                    req.getSession().getServletContext().getContext("/SecureMail")
                        .getRequestDispatcher("/Login.do").forward(req, response);
                } catch (ServletException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
        }
}
