java.io.IOException: Error writing request body to server - web-services

Question

I am developing a web service to allow uploading from client to server. I was able to get wsdl file at http://localhost:9999/UploadWebservice?wsdl. Here is its content
<?xml version="1.0" encoding="UTF-8"?>

<port name="ImageServerImplPort" binding="tns:ImageServerImplPortBinding">
<soap:address location="http://localhost:9999/UploadWebservice"></soap:address>
</port>
</service>
</definitions>
Now I am writing a client to consume the service. Here is the client
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!");
}
}
I receive the following stack trace

The line that causes the problem is delegate.upload("c://Upload//100MB.zip", b);
Why does a published service is still not visible for its client? How can I fix it?
If you have any concern about my coding style please let me know. Things are a little out of my control right now.
Best regards
