<p><a href="https://db.apache.org/ojb">Apache ObJectRelationalBridge (OJB)</a>
moved into the Attic in January 2011. Apache OJB was an Object/Relational
mapping tool that allowed transparent persistence for Java Objects against
relational databases.</p>
<p>The website, downloads and issue tracker all remain open, though the
issue tracker is read-only. The user mailing list has been closed down,
but old posts can be browsed in the
<a href="https://mail-archives.apache.org/">mail archives</a>.
See the website at
<a href="https://db.apache.org/ojb/">http://db.apache.org/ojb</a> for more
information on OJB.</p>
<p>If you are looking for a project to use in place of OJB, implementations
of the standards <a href="https://db.apache.org/jdo">Java Data Objects
(JDO)</a> and <a href="">Java Persistence API (JPA)</a> may be good
starting points. The Apache Software Foundation hosts the following
alternatives:
<ul>
<li><a href="https://cayenne.apache.org/">Apache Cayenne</a></li>
<li><a href="https://incubator.apache.org/empire-db/">Apache Empire-db</a></li>
<li><a href="https://openjpa.apache.org/">Apache OpenJPA</a></li>
<li><a href="https://db.apache.org/torque">Apache Torque</a></li>
</ul></p>
<p>As with any project in the Attic - if you should choose to fork OJB
outside of Apache, please let us know so we can link to your project.</p>
<p>Archived versions of OJB may be downloaded from the
<a href="https://archive.apache.org/dist/db/ojb/">Apache Archives</a>.</p>
