JavaEE 6：java.lang.IllegalStateException：无法检索unitName null的EntityManagerFactory

时间：2011-10-04 11:40:06

标签： jpa-2.0 java-ee-6 glassfish-3

昨天当我在使用我的JavaEE应用程序时，很高兴部署到Glassfish 3.1并且所有[web, ejb, jpa]引擎都正常工作，我能够毫无问题地与数据库进行交互。但是自从我今天开始工作以来，当我尝试从数据库中检索某些内容时，我遇到了java.lang.IllegalStateException: Unable to retrieve EntityManagerFactory for unitName null错误。应用程序仍然没有任何问题进行部署，但这次我看不到[jpa]引擎正在运行。我无法弄清楚为什么我会收到此错误。我没有对Glassfish管理控制台上的may配置或我的应用程序中的任何内容进行任何更改。

我昨天所做的只是使用Glassfish 3.1提供的appclient（ACC）来测试使用@Resource的资源依赖注入。

我完全没有别的。但是今天当我部署我的应用程序时，当我在Glassfish管理控制台上看到我的应用程序上部署的模块和组件时，我看不到[jpa]引擎与[web, ejb]一起列出。

有人可以帮助我理解它为什么会发生以及如何解决这个问题。我已经花了很多时间试图让它工作但我不能看到[jpa]引擎工作给我一个EntityManagerFactory我的应用程序与数据库交谈。

完成堆栈跟踪：

感谢。

答案 0 :(得分：3)

如果您忘记了persistence.xml文件或者文件中未正确设置实体，则会发生这种情况。

答案 1 :(得分：0)

我的应用程序使用Glassfish 3.1.1版。我发现所有三个[web, ejb, jpa]引擎都可以正常使用这个版本的Glassfish。至少现在它的工作，我能够与数据库交谈。我将Glassfish版本从3.1更改为3.1.1，并使用Glassfish管理控制台配置资源。

我需要为服务器添加mysql-connector-java-5.1.15-bin.jar以连接MySql 5.5，而我与Glassfish 3.1版本没有关系。另外，3.1.1版本的gf-client.jar位于${GLASSFISH_HOME}/lib目录中，但不在${GLASSFISH_HOME}/modules目录中。

我不确定它是否是Glassfish 3.1中的错误。
