Projects / OpenCms


OpenCms is a professional level open source Web site content management system. OpenCms helps to create and manage complex Web sites easily without knowledge of HTML. An integrated WYSIWYG editor with a user interface similar to well known office applications helps the user create the contents, while a sophisticated template engine enforces a site-wide corporate layout. OpenCms is based on Java and XML technology, so it fits perfectly into almost any existing modern IT infrastructure. OpenCms runs in a "full open source" environment (e.g. Linux, Apache, Tomcat, MySQL) as well as on commercial components (e.g. Windows NT, IIS, BEA Weblogic, Oracle DB).
