08 November 2007 - Apache Cocoon 2.2 RC2 Now Available

The Apache Cocoon Community is proud to announce the second release candidate of Cocoon 2.2.

Apache Cocoon is a Spring-based framework (since version 2.2) built around the concepts of separation of concerns and component-based development.

Cocoon implements these concepts around the notion of component pipelines, each component on the pipeline specializing on a particular operation.

Cocoon 2.2 introduces blocks. A block is the unit of modularization in Cocoon (in comparison: Eclipse uses the term plugins, OSGi uses bundles). Everything that goes beyond what Cocoon provides in its core modules (Spring integration, sitemap and pipeline implementation) is provided as block (see below). Custom Cocoon applications are also developed as blocks. A block can provide the following features:

• general servlet services (any servlet can be managed by the Cocoon servlet-service framework),
• special services that provide pipelines as services,
• component services (Spring beans, Avalon services/components),
• a container for classes and resources.

A block is packaged as a Java archive (jar) following certain conventions concerning the directory structure.

Find information about the new features at http://cocoon.apache.org/2.2/1420_1_1.html.

For more information about Apache Cocoon 2.2, please go to http://cocoon.apache.org or follow our getting started guide at http://cocoon.apache.org/2.2/1159_1_1.html.

The release artifacts are available from the central Maven repository (http://repo1.maven.org/maven2/).

Project Info -- Apache Cocoon

Apache Cocoon is a web development framework built around the concepts of separation of concerns (making sure people can interact and collaborate on a project, without stepping on each other toes) and component-based web development. Cocoon implements these concepts around the notion of "component pipelines", each component on the pipeline specializing on a particular operation. This makes it possible to use a "building block" approach for web solutions, hooking together components into pipelines without any required programming.
