我们必须将在WebSphere 6.1下运行（相对）正常的Web应用程序转移到WebSphere 7（现在）。
该应用程序使用EclipseLink而不是WebSphere 7中的JPA支持。
我们收到一条消息，表明WebSphere不支持JPA 2.0（即它抱怨persistence.xml文件中的2.0相关条目）所以我们为此安装了功能包。
我们没有扩充现有的配置文件（因为它通常用于另一个应用程序而我们不想弄乱它）并创建了新的配置文件。
现在据我所知，WebSphere 6.1也有不同的JPA支持，但它没有引起任何问题，现在看起来在WebSphere 7内部/股票JPA支持导致问题。
我目前收到的错误消息是

我知道提供JPA支持的库名称很奇怪，而且我不能做太多，因为我通常不是应用程序开发团队的一部分，我只是暂时借给了那个团队。该库是MAVENized并包含多个库，这是我不喜欢的因为它可能导致的依赖性问题（我知道它可以修复它们，但不是我们使用它们的方式）。
我不是JPA大师，远非它，实际上我直到最近才听说过它。我听说过实现它的Hibernate（但实际上并没有使用它），但这不是我们在这里使用的......
我对这个应用程序的了解是它使用JPA注释而不是映射文件，因此我无法提供它所抱怨的“mapping-file”条目。
我们目前正在使用WebSphere 7.0.0.33，它使用功能包“扩充”以提供JPA 2.0支持和EclipseLink 2.3.2。
有人知道可以做些什么来解决这个问题吗？
谢谢！
答案 0 :(得分：1)
它抱怨因为persistence.xml违反了schema。元素提供程序应出现在元素非jta-data-source 之前：
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<non-jta-data-source>jdbc/b2bv</non-jta-data-source>
