is it possible to create or extend a JPA annotation for mapping Enums.
for example, @Enumerated is missing a couple of features, it only allows mapping the Enum index or string(getName).

I would like to extend or create a new annotation to accept two more parameters Field and type to be able to return any field inside a specific Enum. Or give the options to start at index 1 instead of 0.

PL: java
thanks

Perhaps you should Google about JPA annotations in general. Perhaps this will help:
