我正在将现有的应用程序从WAS 8.0迁移到WAS Liberty Profile。
该应用程序是一个EJB Web应用程序，由JSF 2.2，EJB 3，JPA-Eclipselink 2.5.1组成。
我创建server.xml并尝试在WAS Liberty Profile上运行此应用程序。我遇到以下错误：

有没有人遇到过这种错误？ 我的配置中是否遗漏了任何内容？
请告诉我。
答案 0 :(得分：3)
应用程序中的EclipseLink与Liberty中的内置EclipseLink冲突。要在没有内置JPA提供程序的Liberty中使用JPA，请在服务器配置中指定jpaContainer-2.1功能而不是jpa-2.1功能。
