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

问题描述

我是EJB的新手。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。应用程序已经在我们的生产服务器中运行。但是当我部署应用程序时，我遇到异常。

我们正在使用Glassfish应用服务器

堆栈跟踪异常：

  c $ c> hibernate-annotations.jar 文件在服务器的 lib 文件夹中是不同版本的。
 
有人可能改变了它。现在它的工作正常
 
 
 
谢谢。

Here also you can see the same problem at org.hibernate.ejb.Ejb3Configuration.<clinit>(Ejb3Configuration.java:107)  
Could anyone please help me why this error is coming.
It is very much needed.  
Thanks
 解决方案 
Problem Solved.
Actually hibernate-annotations.jar file was of different version in the server's lib folder.
Someone might have changed it. Now its working properly.  
Thank You.
