正如这篇文章所说，它似乎与数据源的名称有关。先尝试一下，看看是否收到第二个错误： https ://www.ibm.com/developerworks/community/forums/html/topic?id=77777777- 0000-0000-0000-000014210826

<jta-data-source>java:comp/...</jta-data-source>不适用于容器管理的 Hibernate JPA。WebSphere Application Server 需要在应用程序中执行几乎所有其他操作之前调用 createContainerEntityManagerFactory，因为该调用可能会注册一个需要修改实体字节码的 ClassFileTransformer。

您的选择是：

  1. 从服务器名称空间（例如， ）中删除<jta-data-source>java:comp/...</jta-data-source>并使用 JNDI 名称。<jta-data-source>jdbc/myds</jta-data-source>

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

我同意@bkail 的观点。
我在 WAS 7 上运行时遇到了类似的问题。在答案中的第一个选项之后解决了它。不推荐使用第二个选项，因为客户端使用同一台服务器来托管多个应用程序。
除此之外，我还jbpm-test-5.4.0.Final.jar从WAR 项目中EAR -> Deployment Assembly删除了 jar 文件。WEB-INF/lib否则，仅当 Websphere 检测到 jar 中的数据源时，它才与第一个选项一起使用。
