有一种方法可以返回POJO conatins来自泽西网络服务的对象数组列表作为回复吗？
如果这是我的POJO：
@xmlRootElement
Public class Test implements Serializable {
private List<Object[]> entities;
public List<Object[]> getEntities() {
return entities;
}
public void setEntities(List<Object[]> entities){
this.entities = entities;
}
}
看起来球衣能够反应但无法在客户端解除反击。
这是我在客户端获得的例外情况：
java.lang.NullPointerException: null

我正在使用球衣1.12。
有谁知道我的问题在哪里？
感谢。
