We are asked to change some software. At the moment one of the things
that has to be replaced is Hibernate. They want to use straight JPA,
so it is easy to switch from Hibernate, to openJPA, to …

One of the annotations that is used is:
    @NotEmpty(message = "Field is not filled")
with the import:
    import org.hibernate.validator.constraints.NotEmpty;

My college wants to use:
    @NotNull(message = "Field is not filled")
    @Size(message = "Field is not filled", min = 1)

I do not like this. It certainly is not DRY. (It is used hundreds of
times.) I prefer to define our own NotEmpty. But I have never worked
with annotations. How to do this?

Also what is a good resource to learn about JPA and annotations?
