Answer 4

Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: Name mysql is not bound in this Context 你用的是mysql,而且数据源是在hibernate.cfg.xml里配的。
在src下写个class
　     public static void main(String[] rags){
　　　　　ApplicationContext app=new ClassPathXmlApplication("applicationContext.xml");
         System.out.println(app.getBean("sessionFactory"));
      }
如过成功不了的话，说明你的hibernate.cfg.xml有问题。最抑郁的事到现在你还不知道那个文件出了问题！你应该一个个文件测，找到那个文件出了问题，然后再把文件里的东西注释掉，
看看到底那个配置错了，再跟据错的配置找到相应的类，再解决掉它。

Answer 5

支持楼上的.
把hibernate.cfg.xml贴出来贴出来.我有一个疑问,配置JNDI数据源一般不是在Tomcat的server.xml里配置的吗?

Answer 6

建立sessionFactory  
dataSource我没有找到
在那？

Answer 7

我知道你的问题出在哪了：
      你的.jar文件中少了一个common.pool文件
