从 weblogic StartUp 类中的以下代码从 JPA 获取 EntityManagerFactory 时遇到问题
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("testEJBPU");
logger.info("Created EntityManagerFactory");
Context ctx = new InitialContext();
ctx.rebind("testEJBPU", emf);
上面的代码只返回 OPenJPA EntityManagerFactory 而不是 Hibernate 我的 Presistence.xml 文件中有以下内容
<?xml version="1.0" encoding="UTF-8"?>

并且在应用程序启动时收到以下与 openJPA 相关的错误
