Release Notes -- Apache Jackrabbit -- Version 1.6.0



Apache Jackrabbit 1.6 is an incremental feature release. While remaining compatible with previous releases, Jackrabbit 1.6 introduces a number of new features, improvements and fixes to known issues.

The most notable changes in this release are:

* The RepositoryCopier tool makes it easy to backup and migrate repositories (JCR-442). There is also improved support for selectively copying content and version histories between repositories (JCR-1972).

* A new WebDAV-based JCR remoting layer has been added to complement the existing JCR-RMI layer (JCR-1877, JCR-1958).

* Query performance has been further optimized (JCR-1820, JCR-1855 and JCR-2025).

* Added support for Ingres and MaxDB/SapDB databases (JCR-1960, JCR-1527).

* Session.refresh() can now be used to synchronize a cluster node with changes from the other nodes in the cluster (JCR-1753).

* Unreferenced version histories are now automatically removed once all the contained versions have been removed (JCR-134).

* Standalone components like the JCR-RMI layer and the OCM framework have been moved to a separate JCR Commons subproject of Jackrabbit, and are not included in this release. Updates to those components will be distributed as separate releases.

* Development preview: There are even more JSR 283 features in Jackrabbit 1.6 than were included in the 1.5 version. These new features are accessible through special "jsr283" interfaces in the Jackrabbit API. Note that none of these features are ready for production use, and will be replaced with final JCR 2.0 versions in Jackrabbit 2.0.

Release Contents


This release consists of a single source archive (jackrabbit-1.6.0-src.jar) that contains all the Apache Jackrabbit components. Use the following commands (or the equivalent in your system) to build the release with Maven 2 and Java 1.4 or higher:

jar xf jackrabbit-1.6.0-src.jar cd jackrabbit-1.6.0-src mvn install

The source archive is accompanied by SHA1 and MD5 checksums and a PGP signature that you can use to verify the authenticity of your download. The public key used for the PGP signature can be found at

Upgrading to Jackrabbit 1.6


Apache Jackrabbit 1.6 is fully compatible with the previous 1.x releases. A previous Apache Jackrabbit 1.x installation can be upgraded by replacing the relevant jar files with the new versions and adding some new dependencies. No changes to repository contents are needed.

The Lucene dependency was upgraded to 2.4.1. Note that Jackrabbit 1.6 only works with this version of Lucene, not with earlier versions and possibly not even with later versions due to the tight integration with Lucene internals (JCR-1855).

The POI dependency was upgraded to 3.2-FINAL.

Repository configuration has been extended with options for the repository lock mechanism. No changes to existing configuration files are needed unless you need to use this new feature (JCR-1605).
