如何在axis2下，调用webservice?

startafresh 2006-08-22 07:10:03

在用客户端调用webservice时，错误如下:

org.apache.axis2.AxisFault: services.myService
at org.apache.axis2.description.OutInAxisOperationClient.execute(OutInAxisOperation.java:287)
at org.apache.axis2.client.ServiceClient.sendReceive(ServiceClient.java:457)
at org.apache.axis2.client.ServiceClient.sendReceive(ServiceClient.java:399)
at test.Test1.main(Test1.java:44)
Caused by: java.lang.Exception: org.apache.axis2.AxisFault: services.myService; nested exception is:
java.lang.ClassNotFoundException: services.myService
at org.apache.axis2.AxisFault.makeFault(AxisFault.java:318)
at org.apache.axis2.receivers.AbstractMessageReceiver.makeNewServiceObject(AbstractMessageReceiver.java:60)
at org.apache.axis2.receivers.AbstractMessageReceiver.getTheImplementationObject(AbstractMessageReceiver.java:90)
at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:71)

因为不知道如何调试判断webservice问题出在哪里，请各位大哥费心看一下我的程序，指点一下，万分感谢。

服务端代码:

import org.apache.axiom.attachments.utils.IOUtils;
import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axiom.om.OMText;
import org.apache.axis2.AxisFault;
import java.io.FileOutputStream;
import java.io.*;
import java.util.Iterator;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
public class myService {

public OMElement Hello(OMElement element) throws Exception {
OMElement _name = null;
OMElement _sex = null;
System.out.println(element);

for (Iterator _iterator =element.getChildElements(); _iterator.hasNext();)
{
OMElement _ele = (OMElement) _iterator.next();
if (_ele.getLocalName().equalsIgnoreCase("name")) _name = _ele;
if (_ele.getLocalName().equalsIgnoreCase("sex")) _sex = _ele;

}

if (_name == null || _sex == null) {
throw new AxisFault("Either Name or Sex is null");
}
String mName = _name.getText();
String mSex = _sex.getText();

System.out.println("Hello "+mSex+"."+mName);

设置返回数据
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace ns = fac.createOMNamespace("http://example.org/mtom/data", "x");
OMElement ele = fac.createOMElement("response", ns);
ele.setText("true");

return ele;
}

}

service.xml

<service name="Version">
<description>
This service is to get the running Axis version
</description>
<parameter name="ServiceClass" locked="false">services.myService</parameter>
<operation name="Hello">
<actionMapping>urn:Hello</actionMapping>
