In Detail

OpenCms is a professional-level open-source Website Content Management System, based on Java and XML. Many companies or organizations have requirements that go beyond what is available in the standard OpenCms application. Thankfully, OpenCms can be used by Java developers to create sophisticated add-ons and customizations that extend the power of OpenCms in virtually unlimited directions.

Targeting version 7 of OpenCms, this book is for Java developers interested in extending and further customizing OpenCms through its Java API.

Starting by showing how to set up a development environment for OpenCms work, the book moves you through various tasks of increasing complexity. Some of the common tasks covered are building OpenCms, XML asset type development, templating, module development, user and role setup, and search integration. In addition to these common tasks some more advanced topics are covered such as self-registering users, RSS support, developing custom widgets and extending the administrative interface. All the topics include examples and are presented while building a sample blog site.

The skills you develop will make you an OpenCms developer to be reckoned with!
