我正在Glasfish Application Server上开发JavaEE应用程序。我正在开发，所以我不断部署/取消部署应用程序。
直到几个小时前，当我在部署时出现此错误时，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？

看来，你的domain.xml文件中提到了名为'decreg-entite'的持久性单元，但是jpa配置文件，persistence.xml没有定义所有关于持久性单元的内容。
