The Sakai Collaboration and Learning Environment (CLE) is a Java-based, service-oriented web application that provides a variety of capabilities supporting teaching and learning, portfolios, research, and ad-hoc project collaboration. The Sakai CLE is typically deployed using Apache Tomcat as its servlet container and scalability is achieved by running multiple instances of Tomcat in a clustered environment, each deploying a copy of the Sakai CLE. It integrates with a variety of external authentication services including CAS, Kerberos, LDAP, Shibboleth and WebAuth. A single database, usually MySQL or Oracle, provides a transactional store of information while file storage is typically delegated to NAS or SAN solutions. In most production settings, the Sakai CLE relies on a back-end student information system (SIS) to provide it with student and course information, which the Sakai CLE consults via provider APIs.
The Sakai Collaboration and Learning Environment (CLE) 2.7.2 maintenance release provides over 370 bug fixes that address key areas like accessibility, internationalization, performance and security.
Our thanks go out to the dedicated Sakai Community volunteers from around the world who have made this release possible.
The documentation is presented here for ongoing comment, correction, and clarification, so please use the "Add Comment" link at the bottom of any of these pages if you note errors, require further details or have tips to share.
The Sakai CLE 2.6 series is now unsupported. The release of Sakai CLE 2.8.0 in April 2011 marked the end of official community support for the Sakai 2.6 series. Organizations running Sakai CLE 2.6 (or earlier versions) are strongly encouraged to upgrade to the latest versions of Sakai CLE 2.7 or 2.8 in order to take advantage of continued maintenance support.
