我正在尝试部署一个小应用程序，但当我使用deJBoss配置按下run时，我会得到以下异常：

我的persistence.xml，我在其他帖子中搜索，但我无法解决问题。我是JBoss和Intellij IDEA的新手。

我通过将JTA数据源放在persistence.xml中修复了这个错误，但JBoss告诉我缺少这个数据源。
service jboss.naming.context.java.sample (missing)
您需要在添加的MySQL模块上添加一个模块依赖项。
文件如下：https://docs.jboss.org/author/display/AS7/Class+加载+in+AS7
您可以使用MavenWAR插件在MANIFEST.MF文件中添加Dependencies:com.mysql行。或者您可以添加一个jboss-deployment.xml文件。
