请在下面找到persistence.xml条目：

这篇文章似乎与数据源的名称有关。首先尝试一下，看看你是否得到了第二个错误： https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014210826

答案 1 :(得分：0)

<jta-data-source>java:comp/...</jta-data-source>与容器管理的Hibernate JPA不兼容。 WebSphere Application Server需要在执行应用程序中的其他所有操作之前调用createContainerEntityManagerFactory，因为该调用可能会注册需要修改实体字节码的ClassFileTransformer。

您的选择是：

  1. 删除<jta-data-source>java:comp/...</jta-data-source>的使用并使用服务器命名空间中的JNDI名称（例如<jta-data-source>jdbc/myds</jta-data-source>）。

  2. 如APAR PM26361中所述，为应用程序禁用容器管理的JPA。 （此APAR描述了在应用程序启动期间调用createContainerEntityManagerFactory导致的性能问题，但该属性也可用于避免此问题。）当然，禁用容器管理的JPA意味着您无法再使用@PersistenceUnit / { {1}}注释或@PersistenceContext / <persistence-unit-ref>。

答案 2 :(得分：0)

我同意@bkail的意见 在WAS 7上运行时我遇到了类似的问题。在答案的第一个选项之后解决了它。建议不要使用第二个选项，因为客户端使用相同的服务器来托管多个应用程序 除此之外，我还从jbpm-test-5.4.0.Final.jar中移除了jar文件EAR -> Deployment Assembly以及WAR项目中的WEB-INF/lib。否则它只能用于第一个选项，因为Websphere在jar中检测到数据源。
