search GAL in zimlet

Please tell me how to search GAL in a zimlet.
I want to get datas from GAL in a zimlet.

It's a bit more complicated than just:
"Tell me how to. . ."

You need to build a base zimlet first:

I wrote a code like this.

Code:

---

HandlerObjectName.prototype._searchGal =
function() {
    var url = "/service/soap";

    var reqHeader = {};

    var data = '<?xml version="1.0" encoding="utf-8"?>' +
                  '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">' +
                  '<soap:Header>' +
                  '<context xmlns="urn:zimbraAccount">' +
                  '<nosession/>' +
                  '</context>' +
                  '</soap:Header>' +
                  '<soap:Body>' +
                  '<SearchGalRequest><name>"userName"</name></SearchGalRequest>' +
                  '</soap:Body>' +
                  '</soap:Envelope>';
 
    AjxRpc.invoke(data,
                        url,
                        reqHeader,
                        new AjxCallback(this, this._callback));

};

HandlerObjectName.prototype._callback =
function(obj, result) {
    alert("obj.text = " + obj.text);
};

It occurred UNKNOWN_DOCUMENT Exception.
