我是EJB的新手。我的经理告诉我在测试服务器中部署ejb应用程序进行一些修改。该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，我遇到了异常。
我们正在使用Glassfish应用服务器
堆栈异常跟踪:

在这里您还可以看到相同的问题
at org.hibernate.ejb.Ejb3Configuration.<clinit>(Ejb3Configuration.java:107)有人可以请帮助我为什么会出现此错误。
这是非常需要的。
谢谢
最佳答案
问题解决了。
实际上，hibernate-annotations.jar文件在服务器的lib文件夹中具有不同的版本。
可能有人更改了它。现在其正常工作。
谢谢。
