ObJectRelationalBridge (OJB) is an Object/Relational mapping tool that allows transparent persistence for Java objects against relational databases. It supports multiple persistence APIs, including JDO, ODMG, and several custom alternatives.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
This release adds OQL parameter binding operation and OQL filter
operations in ODMG Collection, and a tutorial and a code example
covering Conversion Strategies. DListImpl, DBagImpl, DSetImpl,
DMapImpl, and the respective Iterators now provide remove() methods.
The __ prefix has been removed from the OJB internal tables, to allow
easier ports to Oracle, DB2, and other DBMS. To minimize the size of
serialized Identities, they are now GZIPed. The RsIterator methods
next() and hasNext() have been rewritten to work even with buggy JDBC
2.0 drivers. Creation and preparation of prepared Statements is now
compliant with JDBC 2.0 drivers for DB2 and Oracle. ojb.server has
been renamed to ojb.odmg to better reflect its content. The deletion
sequence for depended objects has been changed to prevent referential
integrity violations.
