做一个Hibernate小例子,出现如下问题~~~:*

[Strawberry79]

我找一个hibernate的小例子,其中hibernate.properties文件如下:
## Oracle

#hibernate.dialect net.sf.hibernate.dialect.Oracle9Dialect
hibernate.dialect net.sf.hibernate.dialect.OracleDialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.username water
hibernate.connection.password water
hibernate.connection.url jdbc:oracle:thin:@10.3.8.48:1521:ORADB

我使用的是oracle数据库

下面写了一个插入数据的类,代码如下:
public class TestPersonModel2 {

private static SessionFactory sessionFactory;

public static void main(String[] args) throws Exception{
Configuration conf= new Configuration().addClass(PersonModel.class);

//在表中插入第一条数据

sessionFactory = conf.buildSessionFactory();
Session s = sessionFactory.openSession(); *****报错*****

Transaction t = s.beginTransaction();

PersonModel p1=new PersonModel();

p1.setName("robin");
p1.setAddress("上海");

//2.持久化
s.save(p1);

//此时p1已经可以在数据库中找到
t.commit();
s.close();
}
}

输出错误信息如下:

请问这是什么问题?(在网上搜了许久,没有找到答案,多谢指点!)

另:hibernate.properties和hibernate.hbm.xml建议使用哪一个,有何区别,我有点概念不清

[yufanzx]

1。你的lib目录下缺少一个叫jta.jar的包
2。除了语法不同，效果完全一样

太感谢了,的确是这么回事~!:)
