500 Dispatch to method returned an exception(hibernate错误)
这段代码本来是正确的,但是放到Struts就报错,是怎么回事? 
Session session=HibernateSessionFactory.getSession(); 
int pageSize=5; 
int currentPage=2; 
Query qy=session.createQuery("from Product"); 
int count=qy.list().size(); 
int totalPage=(count-1)/5+1; 
System.err.print(totalPage); 
qy.setFirstResult((currentPage-1)*pageSize); 
qy.setMaxResults(pageSize); 
List list=qy.list(); 
for(int i=0;i <list.size();i++){ 
Product product=(Product)list.get(i); 
System.err.println(product.getMember().getMemberName()); 


报错:
