Jackrabbit Status June 2009

Apache Jackrabbit is a fully conforming implementation of the Content Repository for Java Technology API (JCR, specified in JSR 170).

The Apache Jackrabbit project is in good shape. We have no board-level issues at this time.


We made the following releases from the 1.5 branch:

  • Apache Jackrabbit 1.5.4 on April 7th
  • Apache Jackrabbit 1.5.5 on April 28th
  • Apache Jackrabbit 1.5.6 on June 4th

We also made the first alpha release of the upcoming Jackrabbit 2.0:

  • Apache Jackrabbit 2.0 alpha1 on June 4th


The current Jackrabbit trunk and the 2.0 alpha1 release have a system dependency to an early “for review only” version of the JCR 2.0 API jar from JSR 283. No major concerns were raised when this case was discussed on the legal-discuss@ mailing list.

Community / Development

Jackrabbit was present at the ApacheCon EU where we also organized a quite successful JCR meetup.

The CMIS effort that started in the Jackrabbit sandbox has now become the Apache Chemistry project in the Incubator. The other podling with Jackrabbit as the sponsoring PMC, Apache Sling, is just about to graduate into a standalone TLP.

The JCR 2.0 specification (JSR 283) is expected to become final in a few months, as soon as we've completed the required RI and TCK work in Jackrabbit trunk. We're producing source-only alpha releases of the 2.0 codebase to give people a chance to review all the new features and to better track our progress.

We are also planning to release Jackrabbit 1.6 as the last minor release from the 1.x branch that's still based on the JCR 1.0 API.


We are about to start using the Nexus installation at for staging and deploying our releases to the Maven repository.
