The OJB native JDO is both incomplete and undocumented. The backend necessary to support JDO is in place (via the OTM) but I think there just hasn't been enough demand for full JDO support, yet.

It is my personal goal to get a solid implementation into 1.1, but for 1.0 the JDORI plugin is the only real JDO option. It works pretty well from what I hear, but I have only fiddled with it and not built any large apps with it. The biggest thing to do if you want to lessen the need for changes when native JDO is available in OJB is probably to use the OTM directly.

You can also always help implement the JDO API on top of OJB ;-)

I wonder if some could give me a little more in depth status of JDO in

Specifically, from looking at the mail archives I understand that in
addition to the JDO ref. mask, there is some native JDO already
implemented. So I'm wondering if what's available is buggy or just
incomplete and is this documented anywhere other than looking through
the source.

My reason being is I have a facade pattern to OJB as my ORM, but I was
hoping to use as much JDO as possible to lessen the change when it
becomes fully available.

thanks
