Caused by: java.lang.NoSuchMethodException: javax.xml.bind.annotation.XmlElementRef.required()

在用java做webservice 的过程中，遇到的这个问题：

工具：myeclipse

jdk: 1.6

调用代码：

package com.client.demo;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;


public class Demo {
	public static void main(String args[]){
		JaxWsDynamicClientFactory clientFactory = JaxWsDynamicClientFactory.newInstance();
		Client client =  clientFactory.createClient("http://leyooo:8281/services/Staff?wsdl");
		try {
			//staff 人员接口
			int limit = 1;
			//如果有多个参数，直接在后面追加,参数对应的数据类型要正确
			//例:Object[] rsp = client.invoke("staffInfo",limit1,limit2,limit3);
			Object[] rsp = client.invoke("staffInfo",limit);
			System.out.println("return: " + rsp[0]);
		} catch (Exception e) {
			//e.printStackTrace();
			System.out.println(e.getMessage());
		}
	}
}

错误信息：

问题：

     开始自己在eclipse下做的，测试均无问题，我的机器JDK是1.7版本，在与第三方人员进行联调测试时出现了以上的错误，他们使用的工具是myeclipse, JDK 1.6。myeclipse自带JDK版本也是1.6，这个问题很奇怪！ google了下，看到很多解释说是其中几个jar包与jdk1.6不兼容的问题。

以下三个包：

jaxb-xjc-2.2.5.1.jar

jaxb-impl-2.2.5.1.jar

jaxb-api-2.2.5.jar

替换为：

jaxb-xjc-2.1.13.jar
jaxb-api-2.1.jar
jaxb-impl-2.1.3.jar

替换完后，运行搞定！
