BigBlueButton LTI Integration
=============================
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 BBB-LTI Plugin into a BigBlueButton server.
With this plugin you can
- Enable a BigBlueButton server to be a LTI provider
- With a LMS acting as a consumer, allow users to create and join meetings using LMS external tools
Development
=============
The plugin is a grails project that can be compiled using the bbb-web components installed in any BigBlueButton development environment.
To generate the war file
grails clean
grails war
Deployment
=============
Place the war file into the tomcat webapps directory and restart tomcat
sudo cp lti-0.1.war /var/lib/tomcat6/webapps/lti.war
Configure the properties
sudo vi /var/lib/tomcat6/webapps/lti/WEB-INF/classes/lti.properties
Edit the URL and Salt of the BigBlueButton server you are going to connect to
bigbluebuttonURL=http://yourbigbluebuttonserver.com/bigbluebutton
bigbluebuttonSalt=yoursalt
Edit the LTI basic information
ltiEndPoint=http://yourbigbluebuttonserver.com/lti/tool.xml
ltiConsumers=demo:welcome,consumer1:secret1
Restart tomcat
sudo service tomcat6 restart
When running on the BigBlueButton server, create the map to this new application on nginx
How to use the service
======================
You need:
1. A server running any LMS which is a LTI consumer compliant
2. A BigBlueButton 0.8 server running on a separate server (not on the same server as your LMS)
3. A server running the plugin (It can be your bigbluebutton server or any other java application server)
Add a new external tool
In the LMS create a new external tool using the parameters added in the configuration file
Ej.
Consumer Key: demo
Shared Secret: welcome
URL: http://yourbigbluebuttonserver.com/lti/tool.xml
The BigBlueButton roles are assigned according to the roles in the LMS.
