Registering Converters in JPA 2.1 with EclipseLink

Question

On JavaEE environment, I use JPA 2.1 implementation with EclipseLink,

I have some entities that contain enums. So I have created converters for these enume

Answer 1

My guess is that you have intermixed javax.persistence and org.eclipse.persistence.annotations packages.

Using javax.persistence package classes, you may use an empty Converter annotation on the converter class and a Convert annotation on the entity class specifying the converter class.
