热部署后的未知实体bean类：netbeans 6.9 + glassfish 2.1 + eclipselink jpa 2.0

Question

当我部署应用程序时，它可以完美工作，直到我进行更改，保存并由Netbeans热部署该应用程序为止。此时，我在具有@entity的类上收到了一个未知的实体bean类错误，它包含在我的persistence.xml中。发生这种情况时，处理jpa的所有内容都会停止工作。只有重新启动服务器后，我的jpa内容才能再次开始工作。

如果我在项目中关闭了部署保存功能，而仅手动保存和部署，我将得到相同的结果。

这仅仅是netbeans / glassfish错误吗？还是我的jpa设置有问题？

例外

java.lang.IllegalArgumentException: Unknown entity bean class: class amc.nase.idms.persistence.model.SecSession, please verify that this class has been marked with the @Entity annotation.

Answer 1

问题是重新部署后仍保留了旧的持久性单元，并保留了对旧类的引用。确保旧的EntityManagerFactory正在关闭。Glassfish应该为任何托管工厂（例如SessionBean）处理此问题，但是如果您要管理自己的工厂，则需要确保将其关闭。
