The Apache Jackrabbit community is pleased to announce the release of Apache Jackrabbit version 1.2.1. The release is available for download at:

Release Notes -- Apache Jackrabbit -- Version 1.2.1

Introduction ------------

Apache Jackrabbit is a fully conforming implementation of the Content Repository for Java Technology API (JCR). A content repository is a hierarchical content store with support for structured and unstructured content, full text search, versioning, transactions, observation, and more. Typical applications that use content repositories include content management, document management, and records management systems.

Apache Jackrabbit 1.2.1 is an incremental release that introduces a number of new features, improvements, and bug fixes. The most notable changes in this release are the introduction of a clustering feature and various query improvements. The build environment has been upgraded to Maven 2 along with updates to the project structure and new versions of the Apache Lucene and Apache Derby dependencies. See below for the complete list of changes.

Release Contents ----------------

The release consists of a single source archive and a number of pre-compiled binary component archives.

* Jackrabbit source code (jackrabbit-1.2.1-src.jar)

The main source archive contains a "jackrabbit-1.2.1-src" directory with the full released source code and build environment. Use the following commands (or the equivalent in your system) to build all the released components with Maven 2:

$ jar xf jackrabbit-1.2.1-src.jar $ cd jackrabbit-1.2.1-src $ mvn install

The components contained in the released source archive are listed below (with the pre-compiled binary archives in parenthesis):

* Jackrabbit API (jackrabbit-api-1.2.1.jar)

Interface extensions that Apache Jackrabbit supports in addition to the standard JCR API.

* Jackrabbit JCR Commons (jackrabbit-jcr-commons-1.2.1.jar)

General-purpose classes for use with the JCR API.

* Jackrabbit JCR Tests (jackrabbit-jcr-tests-1.2.1.jar)

Set of JCR API test cases designed for testing the compliance of an implementation. Note that this is not the official JCR TCK!

* Jackrabbit Core (jackrabbit-core-1.2.1.jar)

Core of the Apache Jackrabbit content repository implementation.

* Jackrabbit Index Filters (jackrabbit-index-filters-1.2.1.jar)

Text indexing filters for Jackrabbit. Includes example filters for Adobe PDF and MS Excel, PowerPoint, and Word.

* Jackrabbit JCR-RMI (jackrabbit-jcr-rmi-1.2.1.jar)

RMI network layer for the JCR API.

* Jackrabbit WebDAV Library (jackrabbit-webdav-1.2.1.jar)

Interfaces and common utility classes used for building a WebDAV server or client.

* Jackrabbit JCR Server (jackrabbit-jcr-server-1.2.1.jar)

WebDAV servlet implementations based on JCR.

* Jackrabbit Web Application (jackrabbit-webapp-1.2.1.war)

Deployable Jackrabbit installation with WebDAV support for JCR.

* Jackrabbit JCA Resource Adapter (jackrabbit-jca-1.2.1.rar)

J2EE Connector Architecture (JCA) resource adapter for Jackrabbit.

All files contain a README.txt file with more information. Note that external runtime dependencies are only included for the war and rar archives. Other dependencies can be downloaded either manually or automatically using the Maven build system.

Each release file is accompanied by SHA1 and MD5 checksums and a PGP signature. The public key used for the signatures can be found in the KEYS file located in the parent directory.

Upgrading from previous 1.x releases ------------------------------------

Apache Jackrabbit 1.2.1 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 (see below). No changes to repository contents are needed.

The most notable effect of the component restructuring in this release is that the previous jackrabbit-core component has been split in three pieces: jackrabbit-api, jackrabbit-jcr-commons, and jackrabbit-core. Thus you need to replace the previous jackrabbit-core-1.x.jar file with the three new jar archives.

The structure of the WebDAV components have also changed. WebDAV support now consists of the webapp component jackrabbit-webapp-1.2.1.war and the library archives jackrabbit-webdav-1.2.1.jar and jackrabbit-jcr-server-1.2.1.jar.

The Apache Lucene dependency used for full text indexing has been upgraded to version 2.0 in this release. Lucene 2.0 is able to continue using existing index files, but you can also manually recreate the index with Lucene 2.0 extensions by removing the "index" directories of a closed repository. Jackrabbit will automatically re-index content when the repository is next started.

Also the Apache Derby dependency has been upgraded to version 10.2. Like Lucene, the new Derby version can keep using existing database files. New repositories and workspaces will however be created using extensions and improvements introduced in the 10.2 version.
