        }         public static void main(String[] args) {

Answer 1

com.ywh.jaxws.DoSomething could not be found缺少这个class，或是路径不正确。

Answer 2

成功了
package com.ywh;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.xml.ws.Endpoint;
@SOAPBinding(parameterStyle=ParameterStyle.BARE)
@WebService(serviceName="Java6WebService" ,targetNamespace="http://ywh.com")
public class Java6WebService { 
 @WebMethod
 @WebResult(name="doSomethingResponse")
 public  String  doSomething(@WebParam(name="input")String input){
  return  "hello:"+input;
 };
 public static  void main(String[] args){
  Endpoint.publish("http://localhost:8887/GeoGlobeServer", new Java6WebService());
 }; }
