本文介绍了javax.persistence.PersistenceException：无效的persistence.xml的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在Eclipse中使用Servlet，JPA，EJB和JBoss开发项目。正如你可以在我的主题标题中看到的，我的persistence.xml文件中有一个错误，但我不知道哪一个：

但是，当我尝试运行我的servlet时，出现此错误：

存储在您的persistence.xml中
编辑
看起来数据源的JNDI名称是错误的。通常它以以下开头：
java：/
I'm working on project with Servlet,JPA,EJB and JBoss in eclipse. As you can see in the title of my topic I have an error on my persistence.xml file but I don't know which:

How can I fix this issue
解决方案
Unless you didn't copy-paste the complete file, the closing tag is missing. Append
</persistence>
in your persistence.xml
EDIT
It seems that the JNDI name of your datasource is wrong. Usually it starts with :
java:/
