handling Wicket response

Dear All,
How to insert Wicket response into div tag on the page served outside of
Wickets.
This static page looks as follows:

<script type='text/javascript'>
var request;
function doSomeRequest(servletName){
    var servlet = servletName;                //the name (URI) of your
servlet
    var req = servlet;                           //compiling the request
    addrequest(req);                          //calls the addrequest
function
//    request.onreadystatechange = function(){  //this is used to listen for
changes in the request's status
//        document.getElementById('test').innerHTML = req.responseText;
//    }
    if (req.readyState == 4) {
        document.getElementById('test').innerHTML = req.responseText;
    }
    else
        alert("loading "+req.statusText);

}

function addrequest(req) {
    try {                                      //create a request for
netscape, mozilla, opera, etc.
        request = new XMLHttpRequest();
    }catch (e) {

        try {                                  //create a request for
internet explorer
            request = new ActiveXObject("Microsoft.XMLHTTP");
        }catch (e) {                           //do some error-handling
            alert("XMLHttpRequest error: " + e);
        }
    }
    request.open("GET", req, true);             //prepare the request
    request.send(null);                       //send it
    return request;                           //return the request
}
</script>

<form name="TestForm" action="">
    <input type="button" value="Call wicket page" onclick="doSomeRequest('
http://localhost:8080/?wicket:bookmarkablePage=:wicketqs.Page1&username=John'
)">
</form>

<div id="test">
</div>

Page1.java:
public class Page1 extends WebPage {
    public Page1(final PageParameters parameters) {
        add(new Label("message1", "User name is
"+parameters.getString("username")));
    }

}

Page1.html:
<html xmlns:wicket="
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" >
    <head>
        <title>Homepage</title>
    </head>
    <body>
        <span wicket:id="message1">message will be here</span>
    </body>
</html>

Thank you very much in advance
Alex
