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

标签：netbeans-6-9 jpa eclipselink java java-ee


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并且包含在我的persistence.xml中的类上收到一个未知的实体bean类错误.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.

解决方法:

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.
