java调用c#编写的WebService的问题

import javax.xml.namespace.QName;import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;public class Test { /**
 * @param args
 */
public static void main(String[] args) {
byte[] orderinfo=new byte[10];
orderinfo[0]=0x11;
orderinfo[1]=0x12;
orderinfo[2]=0x13;
orderinfo[3]=0x14;
orderinfo[4]=0x15;
orderinfo[5]=0x16;
orderinfo[6]=0x17;
String str = ""; //调用webservice
try {
// URL
String url = "http://192.168.10.154:10064/POPPayDemoService/Service.asmx";

Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL(url)); // SoapRpcMethod:RequestNamespace
call.setOperationName(new QName("http://tempuri.org/su", "TestByte")); call.addParameter("byteval", XMLType.XSD_BYTE,
javax.xml.rpc.ParameterMode.IN); call.setUseSOAPAction(true);

// SoapRpcMethod:Action
call.setSOAPActionURI("http://tempuri.org/rpc7");

str = (String) call.invoke(new Object[]{orderinfo}); } catch (Exception e) {
System.out.println("asdf");
e.printStackTrace();
}
System.out.println(str); }}
请问为什么一调用就出错呢？
关于webservice地址及参数名和Action都是正确的,是不是用byte[]型传不过去啊？webservice那边的TestByte方法中的参数如果定义成String型，我这边也传string型，就正确，现在是byte按理来说也应该可以啊，因为webservice本身就是以字节流形式传输啊，不解，希望高手能给与解答，谢谢

解决方案 »

  1.   

    好像url 地址不对吧， 后面加个 ?WSDL 试试。。
    http://192.168.10.154:10064/POPPayDemoService/Service.asmx?WSDL
      

  2.   

    No returnType was specified to the Call object! You must call setReturnType() if you have called addParameter().
    提示报的错是你传递的时候添加了参数，方法却没有returnType，在call.setSOAPActionURI("http://tempuri.org/rpc7"); 前面加个call.setReturnType(XMLType.XSD_BYTE);
