java.lang.NoClassDefFoundError：无法初始化类org.hibernate.ejb.Ejb3Configuration

我是EJB新手。 我的经理告诉我在我们的测试服务器中部署一个ejb应用程序进行一些修改。 该应用程序已在我们的生产服务器中运行。 但是当我部署应用程序时，我得到了一个例外。

我们正在使用Glassfish Application Server

堆栈跟踪exception：

当我重新启动服务器时，我得到了这些：

在这里你也可以at org.hibernate.ejb.Ejb3Configuration.(Ejb3Configuration.java:107)看到同样的问题at org.hibernate.ejb.Ejb3Configuration.(Ejb3Configuration.java:107)

有谁能帮助我为什么会出现这个错误。
非常需要它。

谢谢

Answer 1

问题解决了。
实际上， hibernate-annotations.jar文件在服务器的lib文件夹中是不同的版本。
有人可能已经改变了它。 现在它正常工作。

谢谢。
