目前我使用JavaScript code发送XML数据GWT。有没有更简单的方法把他们送到？

  sendRequest.addClickHandler（新clickHandler事件（）{

      @覆盖
      公共无效的onClick（ClickEvent事件）{
        // RegisterBuiltin.register（ResteasyProviderFactory.getInstance（））;
        // ItemExtension客户端= ProxyFactory.create（ItemExtension.class，HTTP：//本地主机：8081）;

        sendXMLFFI（restInput.getText（））;

 保护原生无效sendXMLFFI（字符串文本）
  / *  -  {
    VAR XMLHTTP =假;

    如果（XMLHTTP和放大器;！＆安培;！typeof运算XMLHtt prequest =未定义）{
      尝试 {
      XMLHTTP =新XMLHtt prequest（）;
      }赶上（五）{
      XMLHTTP =假;
      }
    }

    如果（XMLHTTP和放大器;！＆安培; window.createRequest）{
      尝试 {
          XMLHTTP = window.createRequest（）;
        }赶上（五）{
          XMLHTTP =假;
        }
    }

    xmlhttp.open（POST，./REST/Items",true）;
    xmlhttp.setRequestHeader（内容类型，应用程序/ XML）
    xmlhttp.send（＆LT; XML版本=1.0编码=UTF-8＆GT;吗？\ n \ N+
           ＆LT;项目吧code ='111'＆GT;＆LT;名称＆gt;富＆LT; /名称＆gt;＆LT;数量＆gt; 100℃/数量＆gt;＆LT; /项目＆gt;中）;
  }  -  * /;
 

解决方案

  RequestBuilder RB =新RequestBuilder（RequestBuilder.POST，./REST/Items）;
rb.setHeader（内容类型，应用程序/ XML）;
rb.sendRequest（＆LT; XML版本=1.0编码=UTF-8＆GT;吗？\ n \ N+
    ＆LT;项目吧code ='111'＆GT;＆LT;名称＆gt;富＆LT; /名称＆gt;＆LT;数量＆gt; 100℃/数量＆gt;＆LT; /项目＆gt;中，
    新RequestCallback（）{...}
）;
 

Currently I use the JavaScript code to send XML data in GWT. Is there an easier way to send them?

 sendRequest.addClickHandler(new ClickHandler() {

      @Override
      public void onClick(ClickEvent event) {
        // RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
        // ItemExtension client = ProxyFactory.create(ItemExtension.class, "http://localhost:8081");

        sendXMLFFI(restInput.getText());

 protected native void sendXMLFFI(String text)
  /*-{
    var xmlhttp=false;

    if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
      try {
      xmlhttp = new XMLHttpRequest();
      } catch (e) {
      xmlhttp=false;
      }
    }

    if (!xmlhttp && window.createRequest) {
      try {
          xmlhttp = window.createRequest();
        } catch (e) {
          xmlhttp=false;
        }
    }

    xmlhttp.open("POST", "./REST/Items",true);
    xmlhttp.setRequestHeader("Content-Type", "application/xml")
    xmlhttp.send("<?xml version='1.0' encoding='UTF-8'?>\n\n"+ 
           "<item barcode='111'><name>Foo</name><quantity>100</quantity></item>");
  }-*/;

RequestBuilder rb = new RequestBuilder(RequestBuilder.POST, "./REST/Items");
rb.setHeader("Content-Type", "application/xml");
rb.sendRequest("<?xml version='1.0' encoding='UTF-8'?>\n\n"+  
    "<item barcode='111'><name>Foo</name><quantity>100</quantity></item>",
    new RequestCallback() { ... }
);
