我正在尝试从本地 tomcat 的战争中部署 OpenXava 项目。它早些时候在不同的主机上工作，所以不要认为代码有任何问题。但是当我点击 URL 时，我收到了上面提到的错误。这是堆栈跟踪：

type Exception report

message org.openxava.util.XavaException: Seems that Feature is not an EJB3 Entity nor transient model class

description The server encountered an internal error that prevented it from fulfilling this request.

项目和模块名称都使用正确的大小写。我想知道这个异常的可能原因是什么。

可能是无法连接到数据库，可能是数据源没有定义，或者定义错误，或者Tomcat中没有JDBC驱动等。在Tomcat日志中的跟踪中，您会找到问题的根本原因。
