在EJB部署中没有正确导出模式

Question

我已经创建了一个带有POJO类“employee”的EJB程序，但是在将EJB部署到JBoss7.1服务器上时，它并没有创建模式（模式没有导出）而没有任何错误。

服务器日志。

Answer 1

我发现您的部署可能存在两个问题：

• persistence.xml文件使用JPA2.1描述符。JBoss AS 7.1.1支持2.0及更低版本。如果您想要2.1.
就应该使用WildFly
• 该类将Identity策略用于自动生成的Ids，并将Oracle10g方言用于持久化单元。Oracle 10g不支持SQL标识的概念，因此您应该选择不同的策略，如sequence或table.
