我的项目正在使用 gwt+maven+hibernate 。并在我的项目中使用库来创建会话工厂

配置配置 = new AnnotationConfiguration(); sessionFactory = configuration.configure(configFile).buildSessionFactory();

并将其返回给我的应用程序。但我得到了例外：

但是当我使用

配置配置 = 新配置（）；sessionFactory = configuration.configure(configFile).buildSessionFactory();

Its throwing :

我不明白缺少哪个 jar，或者我使用的 jar 版本不正确。有人可以帮我摆脱这个例外。

根据http://docs.oracle.com/javase/7/docs/api/java/lang/IncompatibleClassChangeError.html：

当某些类定义发生不兼容的类更改时抛出。当前执行的方法所依赖的某个类的定义已经改变。

我注意到你的类路径中有两个可能冲突的休眠类，一个来自com.appops.server.data.Hibernate另一个来自org.hibernate，这可能是什么导致了你的问题？
