今天遇到一个关于Hibernate程序的异常！请高手帮我解决下！！

源码信息：    
 Session dbsession=HbmOperate.CreateSession();
 HbmOperate.beginTransaction(); 
 String hqlbook="from Bookinfo as b where b.remaining>0 order by b.id desc";  
 Query qbook=dbsession.createQuery(hqlbook);
 
 //此次查询最多只取3条结果
 qbook.setMaxResults(3); 
 System.out.println("测试bb");
 List list=qbook.list();//错误 error
 HbmOperate.commitTransaction();
错误提示：
org.hibernate.exception.GenericJDBCException: could not execute query
