Apache JDO is a subproject of the Apache DB project. JDO is a JCP standard interface for persistence of Java objects. It is datastore-agnostic and supports relational and non-relational databases. For details, please see http://jcp.org/en/jsr/detail?id=243 The Apache JDO project builds the JDO API jars used by application programmers and the JDO TCK jars, used to verify compliance with the specification. The Apache JDO project does not build an implementation of JDO 2.0. The JDO 2.0 Reference Implementation is JPOX, which is available via its own download: http://jpox.org Apache JDO API and TCK are available as a source download from mirrors http://www.apache.org/dyn/closer.cgi /db/jdo/2.0-beta. The jar files are available in binary form as maven form from mirrors /java-repository/javax.jdo and /java-repository/org.apache.jdo JDO 2.0 builds on the JDO 1 API. Applications built to use JDO 1 need only to be recompiled to run with JDO 2.0. Features in the JDO 2.0 release include: - Standard mapping from objects to relational databases - Multi-tier support without use of Data Transfer Objects - Improved query support including projections and aggregates - Stored queries in metadata - Deletion by query - Optimized fetching of object graphs without writing special queries - Extensive List and Map support - Lazy loading of large collections - Better support for single-field primary keys - Object lifecycle event monitoring - Improved support for bidirectional relationships Craig Russell Architect, Sun Java Enterprise System http://java.sun.com/products/jdo 408 276-5638 mailto:[EMAIL PROTECTED] P.S.
