我们在spring应用程序中使用了Hibernate jar.数据持久性由Java Persistence API完成,使用通过上下文xml注入的EntityManagerFactory.

当我们切换到Hibernate 4时,应用程序在tomcat 7中部署时不会停止.以下是错误.

任何人都可以建议停止tomcat可能是什么问题？

我有一个属于2个不同包的同一个类.

package x1.y1.Class
packgage x2.y2.Class

是否有可能如果我正在调用x1.y1.Classvia类加载器,x2.y2.Class而是加载？

如果我尝试设置java.sql.Date为新java.sql.Date(1582-1900,09,14) 它返回我

1582-10-24

所以相差10天.如何解决这个问题呢？
