Hibernate2的分页问题

[bitiliu]

用Hibernate2实现分页，总是抛出异常，数据库用的是MySql 3.21，Server用的是Tomcat5，老是抛出异常Could not execute query！
//--------------------------------------
String hql = "from Article";
Session s = dao.getSession();
Query query = s.createQuery(hql);
query.setMaxResults(5);
query.setFirstResult(2);
List list = query.list();
//--------------------------------------

估计是你的<property name="dialect">配的不对吧,看你的异常好象你选的是ORACLE吧.把hibernate.cfg.xml发上来看看.

呵呵，楼上的一语中的，我设成DB2的了。你是如何看不来的？

1，检查你的映射文件中用的tld，有可能是3.0的版本吧
2，检查你的sql语句。Article是否在配置文件中注册成功。
