JDO Implementations

To build and run your JDO application, you need a JDO implementation. This page lists commercial and non-commercial JDO implementations. For information on how vendors certify compliance with the JDO specifications, see TCK.

JDO Reference Implementations


Below is a list of known implementations of JDO, showing the level of JDO that the implementation tries to implement, and the type of datastore that the implementation supports. You should check the vendors website for details of whether the implementation is fully compliant with the specification claimed - Apache JDO simply provides visibility of known implementations.
