Class LtiLaunchController

java.lang.Object

edu.ksu.lti.launch.controller.LtiLaunchController

public abstract class LtiLaunchController
extends Object

Class to handle the initial launch of an LTI application and creating a session with authentication information from Canvas in it. After the LTI data's signature is verified it will forward the request to an "initial view" that all implementing classes must supply via the getInitialViewPath() method. This initial view method should verify that there is a valid ltiSession with an eID in it and can then serve up its content.
