Javascript Ajax发布到webservice

我需要将数据发布到我的后端系统（SAP）。我正在尝试使用以下代码：

硬编码URL示例：

  var dataString = ""
    //Add TO SAP.
     var aData =  
            jQuery.ajax({
                type: "POST",
                //contentType: "application/xml",
                url: "http://delyo001.you.local:8000/sap/bc/youconsulting/ws/rest/anonymous/z_names_post?firstname=testz&lastname=zefzef",  // for different servers cross-domain restrictions need to be handled
                data: dataString,
                //dataType: "json"

                success: function(xml) { // callback called when data is received
                    //oModel.setData(data);             // fill the received data into the JSONModel
                    alert("success to post");
                },

                error: function(xml) { // callback called when data is received
                    //oModel.setData(data);             // fill the received data into the JSONModel
                    alert("fail to  post");
                    alert(xml);
                }
            });

Web服务通过SOAPUI工作。但不是通过这种方式

谁能告诉我这个代码有什么问题吗

亲切问候,， Vincent

尝试将标题设置为：

标题：{“内容类型”：“application/x-www-form-urlencoded”}

是的，触发了无法发布的警报，问题是它在soapui中工作正常。我无法获得任何特定的错误消息。感谢您的回复，但它不起作用，firebug显示了更多信息：此代码出现新错误：NetworkError:405方法不允许-
