Hibernate创建Sessionfactory时出错 找不出原因？

执行这句时Configuration configuration = new Configuration().configure();
SessionFactory sessionFactory = configuration.buildSessionFactory(); (在这句执行时后台信息：)

希望能从你们这里得到正解 谢谢

你看看是不是你没有将ehcache-x.x.jar放到classpath，我用的是1.2版本，看看你的版本是否太旧之类了

同意楼上
问题的原因是类没找到
java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException

嗯 按你说的做了 但现在出现新的异常
