我有一个EJB 3.2项目，我将它集成到了我的wildfly服务器中。然后，我使用RMI客户端询问我的项目，生成了表，添加到DBMS中没有问题，但当我试图从数据库中恢复时，我收到了以下错误消息：

如果你能告诉我问题出在哪里。我会很感激的提前感谢
ejb调用结果似乎包含对hibernate核心类的引用。尝试将hibernate核心模块的jboss模块依赖项添加到您的项目中。
例如，在您的项目WEB-INF/jboss-deployment-structure.xml或META-INF/jblos-deploymet-structury.xml中，
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="org.hibernate"/>
</dependencies>
</deployment>
</jboss-deployment-structure>
