请教高手：spring +struts2+hibernate 问题

我是一个初学者，在写一个在线购物系统的生成订单时抛出异常，遇到了如下问题，查了好长时间也没解决，望哪位高手帮忙解决一下，谢谢啦
问题如下：description The server encountered an internal error () that prevented it from fulfilling this request.

exception

OrderDaoImpl 中生成订单的代码：
public class OrderDaoImpl extends HibernateDaoSupport implements OrderDao{

public void save(Order order){
getHibernateTemplate().saveOrUpdate(order);

}
。。。。。
