我正在开发一个 Web 服务以允许从客户端上传到服务器。我能够获得 wsdl 文件http://localhost:9999/UploadWebservice?wsdl。这是它的内容

            <output>
                <soap:body use="literal" namespace="http://ws/"></soap:body>

    </binding>
    <service name="ImageServerImplService">
        <port name="ImageServerImplPort" binding="tns:ImageServerImplPortBinding">
            <soap:address location="http://localhost:9999/UploadWebservice"></soap:address>
        </port>
    </service>
</definitions>

现在我正在编写一个客户端来使用该服务。这里是客户端

package ws;

import java.io.IOException;
import java.io.RandomAccessFile;
import java.util.Map;

import javax.xml.ws.BindingProvider;
import javax.xml.ws.soap.SOAPBinding;

import com.sun.xml.ws.developer.JAXWSProperties;

public class ClientTaiwan {    

    public static void main(String[] args) {
        ImageServerImplService service = new ImageServerImplService();
        ImageServer delegate = service.getImageServerImplPort();

        // Enable MTOM
        BindingProvider bp = (BindingProvider) delegate;
        SOAPBinding binding = (SOAPBinding) bp.getBinding();
        binding.setMTOMEnabled(true);

        // Set chunk size           
        Map<String, Object> ctxt =
                ((BindingProvider)delegate).getRequestContext();
                ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);    

        byte[] b;
        try {
            RandomAccessFile f = new RandomAccessFile("c:\\100MB.zip", "r");
            b = new byte[(int) f.length()];
            f.read(b);
            f.close();
            delegate.upload("c://Upload//100MB.zip", b);
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("Done!");
    }
}

我收到以下堆栈跟踪

导致问题的行是delegate.upload("c://Upload//100MB.zip", b);

为什么已发布的服务对其客户端仍然不可见？我该如何解决？如果您对我的编码风格有任何疑问，请告诉我。事情现在有点超出我的控制。

此致
