BigBlueButton Sakai Meeting Tool for Sakai 2.5/2.6/2.7/2.8/2.9/10

BigBlueButton is an open source web conferencing system that enables universities and colleges to deliver a high-quality learning experience to remote students.

These instructions describe how to install the BigBlueButton Meeting Tool for Sakai 2.5/2.6/2.7/2.8/2.9/10.

With this plugin you can
  • Control meetings - create/edit/update/delete BBB meetings from Sakai.
  • Meeting access - define meeting access by selecting all users, groups, roles or individual users in site.
  • Tool access - define who can do what on the Sakai tool.
  • Scheduling - optionally, define meeting start dates and/or end dates and add it to site Calendar.
  • Notification - optionally, send an email notification to meeting participants.
  • Simplicity - the user interface is designed to be simple.
  • Fast - the Ajax driven interface (Javascript + JSON + Trimpath templates) provides good end-user experience and low server load.
  • RESTful - full RESTful support via EntityBroker.
  • Statistics - the tool logs information automatically processed by the Site Stats tool.


You need:

  1. A server running Sakai 2.5+ with entitybroker 1.3.9+
  2. A BigBlueButton 0.8-beta-4 (or later) server running on a separate server (not on the same server as your Sakai site)

Blindside Networks provides you a test BigBlueButton server for testing this plugin. To use this test server, just accept the default settings when configuring the activity module. The default settings are
