Question

我们当前在JBoss 6中运行了一个Java EE 6应用程序。该应用程序在＆persese.xml＆＃39;

中使用了一个自定义的Hibernate持久性提供程序。

自定义持久性提供程序类继承自org.hibernate.ejb.HibernatePersistence。

自定义持久性提供程序打包在应用程序＆＃39; ear＆＃39;文件。

现在，在发生异常后将应用程序部署到JBoss 7.1.1：

我们在这里做错了什么？

Answer 1

这可能就像向org.hibernate添加MANIFEST.MF依赖项一样简单。也可能是您的自定义提供程序不在正确的目录中，EAR/lib是默认情况下的预期位置。

首先看一下class loading documentation。特别是在你的情况下EAR class loading。

使用JBoss 7.1.1自定义Hibernate持久性提供程序
