当我在persistence.xml中添加一个jta-data-source时，我遇到了运行时异常

我的java参考：

@PersistenceContext(name = "CLDB")
private EntityManager cldbManager;

1 个答案:

答案 0 :(得分：1)

您应该使用@PersistenceContext(unitName="CLDB")。 name仅用于控制java:comp/env/名称。在您有第二个unitName之前，<persistence-unit>是可选的，然后您需要指定所需的单位。

（CWWJP0029E消息似乎很差，因为它显示the persistence unit有两个空格，所以它实际上意味着the "" persistence unit。这可能会报告给IBM修复或删除在这种情况下出现错误消息。）
