Hi.

At first I thought that I should ask for DTP, but probably EclipseLink
makes more sense. Do you think that db4o (http://developer.db4o.com) could
be integrated with EclipseLink or EclipseLink is meant to be ORM only?

They are already supporting Eclipse with:

a) an Eclipse plugin to browse stored objects (you can check it out in the
Java/Eclipse getting started video ->
http://developer.db4o.com/blogs/community/archive/2009/05/21 /second-getting-started-with-db4o-video-java.aspx)

b) a second Eclipse plugin to instrument objects to work with db4o
transparently
( http://developer.db4o.com/blogs/product_news/archive/2009/05 /18/automagically-enable-db4o-transparent-persistence-for-ja va-via-eclipse.aspx)

Could this be a start to integrate db4o with EclipseLink or it's only
targeted at ORM with relational datastores?

Best (thx)

While the focus of JPA is object-relational persistence the EclipseLink
project goes beyond relational support already including XML (JAXB and
SDO) as well as non-relational support using JCA resource adapters.

We currently have our hands full building the reference implementation of
JPA 2.0, addressing JAXB 2.1, and the current backlog of community
reported issues and enhancement requests. If someone was interested in
expanding EclipseLink support to handle db4o we would be happy to help get
them started with some guidance. We could then initiate the work within an
incubator component or sub-project and gather user feedback growing a
community of support for this functionality.
