The components in which the annotations of the javax.persistence package can be used differ based on the dependability on the JPA Provider. The annotations that depend on the JPA Provider and the annotations that do not depend on the JPA Provider are described separately:
This point describes the applicability of the annotations that depend on the JPA Provider. The annotations that can be coded in each component are as follows:
The following table lists the annotations that you can code in a WAR file:

The following table lists the annotations that you can code in the Enterprise Beans, exception classes, or the other classes of a library JAR file:
Table 2-22 Annotations (javax.persistence package) that can be coded in a library JAR file (Enterprise Beans, exception classes, or other classes)

Irrespective of the file type, you can use the annotations that do not depend on the JPA Provider, in the entity class.
