我正在 Glasfish 应用服务器上开发一个 JavaEE 应用程序。我正在开发，所以我不断地部署/取消部署应用程序。

直到几个小时前，当我在部署时遇到此错误时，一切都运行良好：

GRAVE: Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare    method
GRAVE: Exception while invoking class org.glassfish.javaee.full.deployment.EarDeployer prepare method
GRAVE: Exception while preparing the app
GRAVE: Could not resolve a persistence unit corresponding to the persistence-unit-ref-name [persistence/decreg-entite] in scope of the module called [declaration-reglementaire-ear#declaration-reglementaire-serviceweb-0.0.3-RELEASE.war]. Please verify your application.
org.glassfish.deployment.common.DeploymentException: Could not resolve a persistence unit corresponding to the persistence-unit-ref-name [persistence/decreg-entite] in scope of the module called [declaration-reglementaire-ear#declaration-reglementaire-serviceweb-0.0.3-RELEASE.war]. Please verify your application.

有没有人知道如何解决这个问题？

谢谢你

看来，您的 domain.xml 文件中提到了名为“decreg-entite”的持久性单元，但 jpa 配置文件 persistence.xml 并未定义有关持久性单元的所有内容。
