org.hibernate.HibernateException: Proxool Provider unable to load JAXP configurator file: proxool.xml

 

环境：    hibernate3.6 、proxool连接池
问题描述： 使用hibernate做orm时因为有一些东西是别人写的，在整合后就出现下面的问题（连接池重复注册）
问题原因： 

Configuration cfg = new AnnotationConfiguration().configure();   //此处重复加载了
		sessionFactory = cfg.buildSessionFactory(); 

　解决办法： 确定程序使用同一个Configuration
