Eclipselink JPARS异常"ECLIPSELINK_OXM_XML_KEY not found“

Question

我使用的是Glassfish 3.1.2和Eclipselink 2.4.1 (至少我是这么认为的！)和derby (来自Glassfish作为JTA资源)。

当通过"XXXX:8080/myapp/ Persistence /访问我的应用程序中的实体时，我得到以下错误。请注意："Eclipselink Persistence Service“是在2.3.2版本中报告的，这对我来说也很奇怪。我希望看到我配置的2.4.1版本(如下所示)。

有什么想法吗？

主要原因是这里使用的Glassfish版本(V3.1.2)：该项目是使用eclipselink 2.4.1构建的，但Glassfish附带了较旧的版本(请参阅日志)。这并不容易修复，但还有另一个堆栈溢出解决方案最终有效：
