spring整合axis，当接口返回List集合时出错

我目前正在使用axis，是在Servlet环境下使用的。并且应用到Spring框架。现在有一个问题：
  我按照例子编写代码，和配置布署文件。
  1，HelloService
  public interface HelloService {
public List<String> sayHello();
  }
  2, HelloServiceBean
  public class HelloServiceBean implements HelloService {
public List<String> sayHello() {
List<String> strList = new ArrayList<String>();
strList.add("abc");
strList.add("bbc");
strList.add("xxx");
return strList;
}
  }
  3,JaxRpcHelloService(继承Spring的超类)
  public class JaxRpcHelloService extends ServletEndpointSupport implements
HelloService {

public List<String> sayHello() {
HelloService helloService = new HelloServiceBean();
return helloService.sayHello();
}

  }
  4,axis对应的服务布署文件
  <service name="HelloService" provider="java:RPC">
<parameter name="allowedMethods" value="*"></parameter>
<parameter name="className" value="cn.leo.jpetstore.webservice.axis.JaxRpcHelloService">       </parameter>
  </service>
  5，生产客户端的配置文件（clientContext.xml）
  <bean id="jaxRpcProxyHello"
class="org.springframework.remoting.jaxrpc.JaxRpcPortProxyFactoryBean">
<property name="serviceFactoryClass">
<value>org.apache.axis.client.ServiceFactory</value>
</property>
<property name="wsdlDocumentUrl">
<value>http://${serverName}:${httpPort}${contextPath}/axis/HelloService?wsdl
</value>
</property>
<property name="namespaceUri">
<value>http://${serverName}:${httpPort}${contextPath}/axis/HelloService
</value>
</property>
<property name="serviceName">
<value>JaxRpcHelloServiceService</value>
</property>
<property name="portName">
<value>HelloService</value>
</property>
<property name="serviceInterface">
<value>cn.leo.jpetstore.webservice.HelloService</value>
</property>


  </bean>
  6，测试用例
  ApplicationContext ctx = new ClassPathXmlApplicationContext(
"clientContext.xml");
  HelloService service = (HelloService) ctx.getBean("jaxRpcProxyHello");
  List<String> list = service.sayHello();
  报如下错误：java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to java.util.List

  7，服务的发布是没有问题的，我也在网上查了很多资料，但是一直没有搞明白。当方法返回单个对象时没有任何问题，现在我个人认为有两个问题点：1，是如何对布署文件进行正确配置。2，是clientContext.xml配置文件还没有配置完全。但是苦于个人水平与时间的限制，没有进一步去研究源码，所以请高手帮忙解答。 --------------------编程问答-------------------- 有个替换方案，不返回List，返回数组 --------------------编程问答-------------------- 你返回的object数组，怎么能当list数组使用，转化下



List<Object[]> temp = (List<Object[]>) query.list();

			List<WorkList> list = new ArrayList<WorkList>();

			WorkList workList = null;

			for (Object[] obj : temp) {

				workList = new WorkList();

				if (obj[1] != null) {

					workList.setObjname(String.valueOf(obj[1]));

				}



……

}

}
