Glassfish 部署异常

Question

我正在 Glasfish 应用程序服务器上开发 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。

一切都很顺利，直到几个小时前我在部署时遇到此错误：

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.

有人知道如何解决这个问题吗？

Answer 1

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信息。
