Question

我正在尝试从我本地tomcat的战争中部署一个OpenXava项目。它早先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，我收到了上述错误。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.

项目和模块名称都在正确的大小写中。我想知道造成这种异常的可能原因是什么。

Answer 1

可能它无法连接到数据库，可能数据源未定义或定义不正确，或者JDBC驱动程序不在Tomcat等中。在Tomcat日志中的跟踪中，您将找到问题的根本原因

OpenXava异常：似乎<module>不是EJB3实体，也不是瞬态模型类
