从 GWT 客户端调用 SOAP Web 服务

我没有任何使用 SOAP 的经验，所以请帮助我。

我在客户端有一个带有 GWT 的网络项目。至于该网站所需的信息，我必须调用/访问 SOAP Web 服务。我读过一些论坛，我应该使用 RequestBuilder 来做到这一点。我有以下代码：

    RequestBuilder builder = new RequestBuilder( RequestBuilder.POST, URL.encode( url ) );

    try {
      builder.sendRequest( null, new RequestCallback() {
        public void onResponseReceived( Request request, Response response) {
            if (200 == response.getStatusCode()) {
                // processing response here
            } else {
                // Handle the error
            }
        }

        public void onError(Request request, Throwable exception) {
            // error
        }

      });
    } catch (RequestException e) {
        // Couldn't connect to server
    }

此代码会导致错误并返回状态代码0。我认为这是 SOP(Same-Origin-Policy)。

我可以通过其他方式访问 GWT 中的 SOAP Web 服务吗？

编辑

在此项目中，.wsdl 文件位于现有域中，

http://sample.com/server/soap/soap.wsdl< /p>

已提供。我也有这个：

http://sample.com/server/soap/soapserver.php< /p>

它有什么帮助我要连接到 SOAP Web 服务吗？

我已经在 java 中创建了一个 SOAP 客户端，但在 javax.xml.* 上遇到了有关继承所需模块的错误。

I don't have any experience working with SOAP so please help me.

i have web project with GWT on the client side. as for the information needed for this site, i have to call/access SOAP web service. i've read some forums that i should use RequestBuilder in order to do so. i have the following code:

    RequestBuilder builder = new RequestBuilder( RequestBuilder.POST, URL.encode( url ) );

    try {
      builder.sendRequest( null, new RequestCallback() {
        public void onResponseReceived( Request request, Response response) {
            if (200 == response.getStatusCode()) {
                // processing response here
            } else {
                // Handle the error
            }
        }

        public void onError(Request request, Throwable exception) {
            // error
        }

      });
    } catch (RequestException e) {
        // Couldn't connect to server
    }

This code causes an error and return status code 0. I think it's the SOP(Same-Origin-Policy) again.

Is there any other way I can do to access SOAP web service in GWT?
