openejb嵌入式容器找不到persistence.xml [英] openejb embedded container cannot find persistence.xml
本文介绍了openejb嵌入式容器找不到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
注意：我尝试将WebContent以及META-INF放在类路径，但这并不帮助。
更新：
在使用openejb + eclipse时，资源查找是非常奇怪的。
- 我将WebContent添加到源文件夹。我停止获取persistence.xml错误，但现在我收到一个错误，表明openejb找不到任何托管资源
- 我将WebContent添加到源文件夹，但使用不同的输出文件夹使用允许输出文件夹的源文件夹），并且persistence.xml错误再次开始发生
- 我将META-INF复制到'test'，这是所有测试的源文件夹，以及所有的运行良好
- 关于点1和2，问题似乎是WEB-INF也被包含在WebContent的一部分。如果我排除WEB-INF，那么再次openejb可以在测试中找到persistence.xml，测试运行正常
我老实无聊关于发生了什么。
我将所有相关错误和代码粘贴到下面。

解决方案
我收到了同样的异常，问题是两个 persistence.xml 在OpenEJB的路径上。
当我删除其中一个时，问题解决了。
异常消息在OpenEJB的一部分是没有帮助的，但是如果您调试到 org.apache.openejb.config.Appmodule 的 hasFailures（）或 hasErrors（）方法，您可以在 EjbModule.getValidation（）中看到更多有用的信息来电！ （4.0.0版）。
I am using openEjb in embedded mode to test a stateless session bean, which has an injected EntityManager. However, when I run the test, it fails because it could not initialize the application. When I see the console I can also see an error related to not being able to find persistence.xml
Note: I tried putting WebContent, as well as META-INF in the classpath, but that does not help either.
Update:
There is something very strange about resource lookups when using openejb + eclipse.
- I added WebContent to source folders. I stopped getting the persistence.xml error, but now I get an error which suggests that openejb could not find any managed resource
- I added WebContent to source folders, but with a different output folder (using allow output folders for source folders), and the persistence.xml error starts occuring again
- I copied META-INF into 'test', which is the source folder for all tests, and everything runs fine
- Regarding points 1, and 2, teh issue seems to be the fact that WEB-INF also gets included as part of WebContent. If I exclude WEB-INF, then again openejb can find persistence.xml in the test and the test runs fine
I am honestly clueless about what is happening.
I am pasting all the relevant errors and code below.

assertNotNull(oSlideService);
this.slideService = (SlideService)oSlideService;
}
//not showing test methods for brevity, since the code fails in setUp itself
}
解决方案
I received the same exception and the problem was that two persistence.xml were on the classpath of OpenEJB.
When I removed one of them, the problem was solved.
The exception message is not helpful here on part of OpenEJB, but if you debug into org.apache.openejb.config.Appmodule's hasFailures() or hasErrors() method, you can see more useful info in EjbModule.getValidation() calls! (Version 4.0.0).
