Speedo is an open-source implementation of the JDO specification. It uses the JORM, Medor and Perseus frameworks defined in ObjectWeb.
The changes since the last release (1.0BETA4), are the following:
- Speedo Eclipse plugin available
- bug fix about empty optimistic transaction
- bug fix about PersistenceManager.refresh(...)
- bug fix about optimistic concurrency
- take in account new jorm configuration
- use Medor expression for inheritance filter
- delete out of transaction is no more allowed according to the JDO
- JDO TCK in progress
- inheritance implementation in progress (JORM ready but not Medor)

I was just wondering if anybody has given this a try yet? Maybe they could post there experience with it. Is it very usable?
I've tried TJDO, Speedo, and looked over OJB but I've had the most success using JPOX. TJDO didn't seem to have as much documentation as I would have liked and Speedo and OJB seem to have a JDO interface placed on top of a prior implmented persistence mechanism which made configuration and debugging more difficult in my opinion. I have not looked at the new Speedo release though. Right now my vote for best open source JDO implementation would have to go to JPOX.
Thanks for the great reply. I had tried TJDO in the Fall, and didn't care for it too much. I also wasn't wild about OJB's plugin architecture. I was unware of JPOX, and will look into that.

The basic documentation was OK. However, I wish that TJDO provided more
Congratulations to the Speedo team on their achievement.
