原因

　　cxf需要jaxws-api-2.1.jar及jaxb-api-2.1.jar的支持。

解决办法

　　1．  检查项目里是否有上述相关Jar包，如果没有，将cxf所需的2.1的jar复制一份到jdk目录下的jre\lib\endorsed文件夹中。如果endorsed文件夹不存在，可新建。

　　2．  项目里是有上述相关Jar包，还需要在public class XXX类上方加入@SOAPBinding(style = SOAPBinding.Style.RPC)；

　　3．  JDK升级到1.6.0.22版本以上；

定义接口方法:
 @WebService
public interface HelloInt {
 
 @WebMethod
 public String sayHello(String name );
}
定义实现类:
@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class HelloImpl implements HelloInt {
 @Override
 public String sayHello(String name) {
  return "hello,"+name;
 }
}
测试方法:
public class ServerTest {
 
 public static void main(String[] args) {
  String address = "http://192.168.1.100:8989/d01ws/hello";
  Endpoint.publish(address,new HelloImpl());
  System.out.println("webservice发布成功");
 }
}

运行程序：

在浏览器地址栏输入：http://192.168.1.100:8989/d01ws/hello?wsdl

可以看到内容，发布成功：
