This feature enables support for applications that use application-managedand container-managed JPA written to the Java Persistence API 2.1 specification. This only includes Java Persistence API 2.1 specification interfaces, and container-managedJPA integration. This feature does not include any JPA implementation.
To enable the Java Persistence API Container 2.1 feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>jpaContainer-2.1</feature>
If you are developing a feature that depends on the Java Persistence API Container 2.1 feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.jpaContainer-2.1; type="osgi.subsystem.feature"
