I have copied the screenshare folder in the webapps folder of Red5. I have 
edited the screenshare.jnlp in this way:

<?xml version='1.0' encoding='utf-8'?>
<jnlp spec='1.0+' codebase='http://localhost/screenshare'> 
    <information> 
        <title>Red5 ScreenShare</title>

    <application-desc main-class='org.redfire.screen.ScreenShare'>
        <argument>localhost</argument> 
        <argument>oflaDemo</argument>

        <argument>screen_share</argument>   
        <argument>flashsv2</argument>       
    </application-desc> 
</jnlp>

and the screenviewer.html like this:

<html>
<head>
<title>ScreenViewer</title>
    <script type="text/javascript" src="swfobject.js"></script>
    <script type="text/javascript">

    var screenViewer = null;

    function setupApp()
    {
        screenViewer = document.getElementById("screenViewerID");

    }

    function stopApp()
    {
        if (screenViewer != null)
        {
            screenViewer.windowCloseEvent();
        }
    }

function getParameter(string, parm, delim) {

     if (string.length == 0) {
        return '';
     }

     var sPos = string.indexOf(parm + "=");

     if (sPos == -1) {return '';}

     sPos = sPos + parm.length + 1;
     var ePos = string.indexOf(delim, sPos);

     if (ePos == -1) {
        ePos = string.length;
     }

     return unescape(string.substring(sPos, ePos));
}

function getPageParameter(parameterName, defaultValue) {

    var s = self.location.search;

    if ((s == null) || (s.length < 1)) {
        return defaultValue;
    }

    s = getParameter(s, parameterName, '&');

    if ((s == null) || (s.length < 1)) {
        s = defaultValue;
    }

    return s;
}

    </script>
</head>
<body topmargin="0" leftmargin="0" bottommargin="0" rightmargin="0" 
onload="setupApp()" onUnload="stopApp()">
<div id="screenViewerDIV"></div>
<script type="text/javascript">

        var stream = getPageParameter('stream', 'screen_share');
        var url = getPageParameter('url', 'rtmp://localhost:5080/oflaDemo'');
        var control = getPageParameter('control', 'true');

        fo = new SWFObject("ScreenViewer.swf?rtmpUrl=" + url + "&recieverStream=" + stream + "&control=" + control, "screenViewerID", "100%", "100%", "9");
        fo.addParam("swLiveConnect", "true");
        fo.addParam("name", "screenViewerID");
        fo.write("screenViewerDIV");
</script>
</body>
</html>

and the command I enter is:

java -classpath screenshare.jar org.redfire.screen.ScreenShare localhost 
oflademo 1935 screen_share flashsv2

Everything looks correct and according to the instructions, but as I press the 
"start Sharing" button, it does not share. The following commands are displayed 
in the console:

Please help me to solve the issue. It is deeply important to deploy the desktop 
sharing on my localhost and then on our server. 

Thanks in advance!
