Hibernate奇怪的问题

两段同样的代码,一个好使,一个却不行!

public class ActiveDAO extends HibernateUtil
{	
	public void updateActivationBySQL(String sql){
		try {
			this.getConnection().createStatement().executeUpdate(sql);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public static void main(String [] args){
		try {
			ActiveDAO ld = new ActiveDAO();

	String sql = "update Activeinfo a set a.doit=2 where a.id=1"; //(不好使) 

       // String sql = "update Report r set r.doit=8 where r.id=1"; (好使)


			ld.updateActivationBySQL(sql);
		} catch (Exception e) {
			System.out.println("eeeeeeeeee: "+e.toString());
		}
	}
}

配置文件:

Activeinfo.hbm.xml:

真是弄不明白,到底哪里出现了问题? 郁闷.....
