Centos JBOSS部署war文件失败，无法加载persistence.xml。在Windows 7上工作但不是centos

我花了两天时间仍然无法解决问题。

我的问题是我有一个使用JPA和Hibernate的war文件。当我在Windows JBOSS AS 7.1.1上部署时，它可以完美运行。但是，当我将它部署在Centos 5.8 JBOSS AS 7.1.1上时，它会抛出异常。根本原因很常见：      引起：javax.persistence.PersistenceException：没有名为XX的EntityManager的持久性提供程序

我不知道为什么它在两个操作系统中的工作方式不同。我在两台机器上都有JDK7更新21。

开发机器：Windows 7（64位），Eclipse IDE，JDK7_21 部署机器：Centos 5.8（64位），

我尝试使用

ClassLoader loader = Thread.currentThread().getContextClassLoader();
Enumeration<URL> resources1 = loader.getResources("/META-INF/persistence.xml");
URL seurl = resources1.nextElement();

但是，这仅适用于Windows 7，在Centos上它没有获取persistence.xml并在调用 .nextElement（）时抛出NOSuchElement Exception。我已将META-INF文件夹作为资源放置，部署时将其放置在此位置xx.war / WEB-INF / classes / META-INF / persistence.xml。

有人可以帮我找出问题所在吗？非常感谢。

我想发布抛出的异常：

1 个答案:

答案 0 :(得分：0)

好的..我已经解决了我自己的问题，这是一个愚蠢的愚蠢答案。

Windows可以理解和处理大写字母，因此 Persistence.xml 等同于 persistence.xml 。虽然在UNIX / Linux中不是。

所以答案是将文件名从 Persistence.xml 更改为 persistence.xml 。
