Wrapper class webservice.jaxws.SayHi is not found. Have you run APT to generate them?

　　最近在研究webservice,利用jdk来实现简单的webservice发布，但是运行时却发生了这样的异常,如下：

Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error: Wrapper class webservice.jaxws.SayHi is not found. Have you run APT to generate them?
 at com.sun.xml.internal.ws.model.RuntimeModeler.getClass(RuntimeModeler.java:256)

最后发现原来是jdk的版本过低，我使用的是jdk1.6.10,而最低要求为1.6.22以上即可，故特此记录下来，谨防再次出错

例外，此种发布方法如下：

第一步：定义接口HelloWorld

package webservice;

import javax.jws.WebService;

@WebService public interface HelloWorld {  

　　String sayHi(String str);

}

第二步：实现类HelloWorldImpl

package webservice;

import javax.jws.WebService;

import javax.xml.ws.Endpoint;

@WebService(endpointInterface = "webservice.HelloWorld") 

public class HelloWorldImpl implements HelloWorld {

 　　public String sayHi(String str) {   

　　　　System.out.println("我是webservice");     

　　　　return "Hello ," + str;   

　　}  

　　 public static void main(String[] args) {

　　　    Endpoint.publish("http://localhost:8088/hello", new HelloWorldImpl());

　　 }

}

第三步：运行HelloWorldImpl.java main方法

第四步：在浏览器地址栏输入：http://localhost:8088/hello?wsdl

第五步：查看响应xml文件：如成功返回如下：
