requêtes JSON qui ne passent pas

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Bonjour,
Je travaille en ce moment à l'intégration d'Alfresco comme ged pour une application existante. Pour ça je souhaite utiliser l'API REST. Je ne comprends pas pourquoi lorsque j'exécute ce code je n'ai rien à l'affichage et rien non plus dans les logs susceptible de m'aider.

<html>
<head>
<title>Simple Ajax Example</title>
<script language="Javascript">
function xmlhttpGet() {
   var strURL="http://isxpre76:8080/alfresco/service/api/login?u='+document.getElementById('login').value+'&pw='+document.getElementById('password').value;
    var xmlHttpReq = true;
    var self = this;
    // Mozilla/Safari
    if (window.XMLHttpRequest) {
        self.xmlHttpReq = new XMLHttpRequest();
    }
    // IE
    else if (window.ActiveXObject) {
        self.xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
    }
    self.xmlHttpReq.open(&#39;GET&#39;, strURL, false);
    self.xmlHttpReq.setRequestHeader(&#39;Content-Type&#39;, &#39;application/xml&#39;);
       self.xmlHttpReq.send();
   updatepage("sdsddssd"+self.xmlHttpReq.responseXML);
}



function updatepage(str){
    document.getElementById("result").innerHTML = "<h1>"+str+"</h1>";
}
</script>
</head>
<body>
<form name="f1">
  <p>login: <input id="login" name="login" type="text"></p>  
  <p>password: <input id="password" name="password" type="text">
  <input value="Go" type="button" onclick=&#39;JavaScript:xmlhttpGet()&#39;></p>
  <div id="result"></div>
</form>
</body>
</html>

ce code retourne null pour XML. j'aimerai donc savoir ne serait-ce que par le biais d'un exemple comment effectuer un appel Json et l'afficher.

Je vous en remercie.
Landry.
