    Speedo 1.0 is available and can be downloaded at:
    http://forge.objectweb.org/project/showfiles.php?group_id=33

    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
    specification.
    - JDO TCK in progress
    - inheritance implementation in progress (JORM ready but not Medor)

  2. I was just wondering if anybody has given this a try yet? Maybe they could post there experience with it. Is it very usable?

  4. Open source JDO projects[ Go to top ]

    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.

  5. Thanks[ Go to top ]

    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.

    I've used TJDO 2.1 (open source) with MySQL's MaxDB database.

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