关于webService 客户端 调用 对象数组 问题

call.invoke 的参数本来就是数组，就不用再在数组里面加数组了
代码如下：

public static void main(String [] args) throws ServiceException, MalformedURLException, RemoteException{
 Logger log=Logger.getLogger(Client.class);
 String nameSpace="http://impl.webservice";
 String method="getAge";
 Service service = new Service();
 Call call=(Call)service.createCall();
 call.setTargetEndpointAddress(new java.net.URL("http://localhost:8070/TEST/services/testMyService?wsdl"));
 call.setUseSOAPAction(true);
 Object[] ss=new Student[2];
 Student s0=new Student();
 s0.setAge("123");
 s0.setName("57");
 ss[0]=s0;
   Student s1=new Student();
    s1.setAge("123");
    s1.setName("213");
    ss[1]=s1;

    QName qn =new QName(nameSpace,method);
    call.setOperationName(qn);
    call.registerTypeMapping(Student.class, qn,
               new org.apache.axis.encoding.ser.BeanSerializerFactory(Student.class, qn),        
              new org.apache.axis.encoding.ser.BeanDeserializerFactory(Student.class, qn));
    for(int i=0;i<ss.length;i++){
        call.addParameter(qn, XMLType.SOAP_ARRAY,   ParameterMode.IN);
    }
    String ret = (String) call.invoke(ss);

    log.info(ret);
    System.out.println(ret);

}
