If you are not tied to a JDO implementation, eQ!
(www.browsersoft.com/eQ) has a very flexible, declarative persistence
layer and it is not tied to an RDBMS datastore. Instead of using
programmatic access like JDO and Torque (which is a really good
persistence layer pulled out of Turbine) it uses a declarative approach.
The link above doesn't have all the full technical details, but you can
find most of those at: (a work in progress).

Oh, and eQ! is built on top of Avalon :-)

Subject: DAO and JDO

Hey everybody,

I was just wondering what the feeling towards the JDO spec is.  I need
some way of persisting objects.  I've looked at torque, but it only
deals with JDBC and I need something that will interface well with JNDI
as well.  I was considering using a JDO implementation, but lo and
behold I can't find an open source one.  So, I was considering writing
one using Avalon and Excalibur.

Before I start working on that, though, I thought I'd ask everyones
opinion and see if anyone has a better idea for object persistence.  I'd
be willing to use something like simplestore, except from what I've seen
it doesn't allow for searching, just retrieval based on a key.

Thoughts?  Ideas?  Anyone willing to help if I do go through with a JDO
