Hibernate連接數據源成功之後, 發生錯誤??

Question

web-inf/jdbc.properties文件贴出来看看。注意里面的jdbc.driverClassName把sqlserver的jar文件放到web-inf/lib目录里

Answer 1

hibernate.cfg.xml文件:<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
   
 <session-factory>
   
     <property name="connection.datasource">java:comp/env/jdbc/hellohibernate</property>
    
    <property name="show_sql">false</property>
      
  <property name="dialect">net.sf.hibernate.dialect.OracleDialect</property>        <mapping resource="com/xanada/po/Cat.hbm.xml"/>
  
  </session-factory>
</hibernate-configuration>

Answer 2

Session session = HibernateUtil.currentSession();
       /*       Transaction tx = session.beginTransaction();
         Query query = session.createQuery("select * from test");
             
            */
            
           // query.setCharacter("sex", 'F');          /*
            for (Iterator it = query.iterate(); it.hasNext();) {
                Cat cat = (Cat) it.next();
                out.println("Cat: " + cat.toString() + "<br>");
            }            tx.commit();            HibernateUtil.closeSession();
            */
        } catch (HibernateException e) {
            e.printStackTrace(out);
        }      
        out.println("</body>");
        out.println("</html>");
    }
}       从我开如注释的地方出错。
        高手指教！
