调用jndi，已经把hibernate 成功的绑定到了jndi上了，如下：
Bind Name: hibernate
Object Class: net.sf.hibernate.impl.SessionFactoryImpl
Object Hash Code: 4669345
Object To String: net.sf.hibernate.impl.SessionFactoryImpl@473fa1

配置文件
<property name="dialect">
net.sf.hibernate.dialect.SQLServerDialect
</property>
<!-- <property name="connection.provider_class">net.sf.hibernate.connection.DatasourceConnectionProvider</property>-->
<property name="connection.datasource">
java:/comp/env/jdbc/mydatasource
</property>
<property name="connection.driver_class">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>

调用jndi
public static Session currentSession() throws HibernateException {
Session session = (Session) threadLocal.get();

if (session == null) {
if (sessionFactory == null) {
try {
Context ctx = new InitialContext();
sessionFactory = (SessionFactory) ctx.lookup("hibernate");
//cfg.configure(CONFIG_FILE_LOCATION);
//sessionFactory = cfg.buildSessionFactory();
}
catch (Exception e) {
System.err.println("%%%% Error Creating SessionFactory %%%%");
e.printStackTrace();
}
}
session = sessionFactory.openSession();
threadLocal.set(session);
}

return session;
}

你的sessionFactory 怎么那样来取呢？不需自己来查询jndi的
通过配置文件Hibernate就会给你产生sessionFactory 了，一般使用一下面一个语句就可以了
sessionFactory = new Configuration().configure().buildSessionFactory();
try {
Context ctx = new InitialContext();
sessionFactory = (SessionFactory) ctx.lookup("hibernate");
//cfg.configure(CONFIG_FILE_LOCATION);
//sessionFactory = cfg.buildSessionFactory();
}
这一段换成
try{
sessionFactory = new Configuration().configure().buildSessionFactory();

}

搞定了，原来是数据源的命名问题
