我的HIBERNATE问题,请大家帮忙

[zs_han]

我做了一个登录页面,后台数据库是ORACLE9I,可是一点登陆就出现如下错误,请大家帮忙看看是什么错误,我用的是tomcat5.5.1.7版本,hibernate是3版本,我是菜鸟,分不多
说明一下,数据库没有问题,因为我不用HIBERNATE,而直接用最原始连接池的办法是可以登陆的.

这样找不出来的！要看看你的配置文件！看看你是怎样映射的数据库！
最好把你的配置文件发下看看！

我的HibernateSessionFactory.class如下:

package com.topsuntech.gUnit.gEU_test.entity;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;

/**
* Configures and provides access to Hibernate sessions, tied to the
* current thread of execution. Follows the Thread Local Session
* pattern, see {@link http://hibernate.org/42.html}.
*/
public class HibernateSessionFactory {

/**
* Location of hibernate.cfg.xml file.
* NOTICE: Location should be on the classpath as Hibernate uses
* #resourceAsStream style lookup for its configuration file. That
* is place the config file in a Java package - the default location
* is the default Java package.<br><br>
* Examples: <br>
* <code>CONFIG_FILE_LOCATION = "/hibernate.conf.xml".
* CONFIG_FILE_LOCATION = "/com/foo/bar/myhiberstuff.conf.xml".</code>
*/
private static String CONFIG_FILE_LOCATION = "/com/topsuntech/gUnit/gEU_test/entity/hibernate.cfg.xml";

/** Holds a single instance of Session */
private static final ThreadLocal threadLocal = new ThreadLocal();

/** The single instance of hibernate configuration */
private static final Configuration cfg = new Configuration();

/** The single instance of hibernate SessionFactory */
private static org.hibernate.SessionFactory sessionFactory;

/**

* the <code>SessionFactory</code> if needed.
*

*/
public static Session currentSession() throws HibernateException {
Session session = (Session) threadLocal.get();

if (session == null || !session.isOpen()) {
if (sessionFactory == null) {
try {
cfg.configure(CONFIG_FILE_LOCATION);
sessionFactory = cfg.buildSessionFactory();
} catch (Exception e) {
System.err
.println("%%%% Error Creating SessionFactory %%%%");
e.printStackTrace();
}
}
session = (sessionFactory != null) ? sessionFactory.openSession()
: null;
threadLocal.set(session);
}

return session;
}

/**

*

*/
public static void closeSession() throws HibernateException {
Session session = (Session) threadLocal.get();
threadLocal.set(null);

if (session != null) {
session.close();
}
}
/**

private HibernateSessionFactory() {
}

}
