XFire Web service 返回Object[]

数据结构：
① public class RespInfo{
       private String resourceCode;
       private String respMessage;
       gettter和setter方法省略
 }
② public class Student{
       private String id;
       private String name;
       getter 和setter省略
 }
③ public interface Test{
   /**
    Object[]的长度是固定的，长度为2
    Object[0]的存放的数据类型为RresInfo类型。
    Object[1]的存放的数据类型为List<Student>类型;
   */
   public Object[] test();
}
我在XFire的客户端调用test（）这个方法的时候,总是报
ERROR(DefaultFaultHandler.java:35)DefaultFaultHandler:35 - Fault occurred!

at java.lang.Thread.run(Thread.java:619)在这里我首先声明一下：
   配置方法是没有问题的，Xfire的面暑方式是和Spring集成的那种形式,
   开发环境:Myeclipe6.5 + JDK1.6.11  + Tomcat6.0.18,
 在网上曾看到过说：在接口的同级目录下创建      接口名.aegis.xml的这样一个文件，然后在这个文件里面做相应配置，但是这种方法只是针对于jdk1.5以下的版本。而我用的是jdk1.6，所以我觉得我用不着配置这个文件.
已经从昨天下午找到今天了，目前还没什么结果，希望各位解答一下！
谢谢了
