This is the Sakai Axis plugin that allows for the Cattura Hardware unit to communicate with Sakai.
To install the plugin, simply copy the Cattura.jws file into your sakai-axis directory. This is typically found in /path/to/sakai/webapps/sakai-axis.
All Sakai integration settings can be found in the settings tab under the LMS integration section. Simply put the web URL to sakai axis (ex: http://myschool.edu/sakai/sakai-axis) and the username and password to a read-only Sakai account.
