configuration of non-standard field types

[Patrick Linskey <pl...@gmail.com>]

Hi,

OpenJPA supports a number of field types beyond what is listed in the
JPA spec. How should people designate that such fields are to be
persisted?

Currently, I believe that people must annotate such fields with
@Persistent. (We may have an exception for the new XML stuff in this
case.) I think that it'd be useful for us to have a consistent story
for these situations.

We should come up with a consistent rule of thumb that will work for
both the new XML code and the code that Ignacio has been working on
for OPENJPA-130.

I think that at the least, we should automatically install
FieldStrategies for all the fields that we can handle.

Should we require @Persistent for non-JPA field types, or
automatically persist them if we know how to?

-Patrick

I would go with making any fields that we know how to persist be  
automatically persistent. Since @Transient is a standard annotation  
but @Persistent is not, it makes more sense to me that people should  
have to opt-out of persisting fields than opt-in.
