Re: Feature Request: allow httpServletRequest parameters to be converted into render parameters on a particular portlet or all portlets on a page.

Try this out, its checked into the head:

package org.apache.jetspeed.container.state.impl;
import java.io.UnsupportedEncodingException;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import javax.portlet.PortletMode;
import javax.portlet.WindowState;

import org.apache.pluto.om.window.PortletWindow;

public class HybridNavigationalState extends SessionNavigationalState
{
    protected String prefix;

    public HybridNavigationalState(NavigationalStateCodec codec, String 
prefix)
    {
        super(codec);
        this.prefix = prefix;
    }

    public String encode(PortletWindow window, Map parameters, 
PortletMode mode, WindowState state, boolean action)
    throws UnsupportedEncodingException
    {
        Map subset = new HashMap();
        Iterator params = parameters.keySet().iterator();
        while (params.hasNext())
        {
            String key = (String)params.next();
            if (key.startsWith(prefix))
            {
                // only encode params that start with prefix
                subset.put(key, parameters.get(key));
            }
        }
        return super.encode(window, subset, mode, state, action);
    }

    public boolean isNavigationalParameterStateFull()
    {
        return true;
    }

    public boolean isRenderParameterStateFull()
    {
        return false;
    }

I would like to suggest a jetspeed2 extension. I would like a way to
allow HttpServletRequest parameters to be converted into render
parameters on a particular portlet or all portlets on a page.


i.e:
http://localhost:8080/jetspeed/portal?_pp=MyPortlet-paramName-paramValue

 or  http://localhost:8080/jetspeed/portal?_pp=ALL-paramName-paramValue

In addition I need a way from portlet to add request params to resulting
redirected post.

i.e: On a form a post occurs. Portlet action fires. In there you can do
a response.sendRedirect. I need either a way to add request parameters
to normal redirected URL or a way to determine what that normal
redirected url would be so I could add the request parameters to it and
pass it to send redirect.

Is is possible?

Thanks,
Garry
