架构未在EJB部署上导出而没有错误

Question

我已经创建了一个带有POJO类"Employee"的EJB程序，但在将EJB部署到JBOSS 7.1 AS服务器时，它没有创建Schema（Schema not Exported）而没有任何错误。

任何人都可以提出建议，程序出了什么问题。

Answer 1

我发现您的部署可能存在两个问题：

• persistence.xml文件使用JPA 2.1描述符。JBoss AS 7.1.1支持2.0及更低版本。如果你想要2.1，你应该使用WildFly
• 该类对自动生成的Id使用IDENTITY策略，并对持久性单元使用Oracle10g方言。Oracle10g不支持SQL IDENTITY的概念，因此您应该选择不同的策略，如SEQUENCE或TABLE
