在tomcat 4.1下测试成功的程序到了tomcat 5.0下就出错了

在tomcat4.1 下hibernate 2.1.2 数据库MySQL4.0
在tomcat4.1 下一切正常
程序如下：
essionFactory sessionFactory=null;
Configuration  conf = null;
Session ses;
conf = new Configuration();

conf=conf.configure();

sessionFactory = conf.buildSessionFactory();
ses = sessionFactory.openSession();
Transaction tran = ses.beginTransaction();
String sql = "from Person as person ";
Query query = ses.createQuery(sql);
Iterator it= query.iterate();


while(it.hasNext())
{
Person per = (Person)it.next();

out.println(per.getAddress());
}

tran.commit();
ses.close();


但到了tomcat 5.0下
出现的以下的错误：
description The server encountered an internal error () that prevented it from fulfilling this request.

请各位指教
谢谢！

你是不是XX阿？

javax.servlet.ServletException: Could not find datasource: Name jdbc is not bound in this Context

Name jdbc is not bound in this Context

楼上的 我数据源配置了 并测试了可以连接
但是用hibernate 之后就不行了

好好差差，肯定是少加了一些包。在webapp中。

tomcat4.0和tomcat5.0以上版本配置数量源的方法不同了，重配一下吧。

谢谢大家的关注，是因为hibernate包的问题，现已经解决

数据原配置乐吗？
