Example usage of auth widget with call to auth_info api with resulting token from Java.
You'll need to configure your Engage api key (secret) in the src/main/webapp/WEB-INF/web.xml.
There's a minimal web page in src/main/webapp/index.html with the <script> tag and <div> for a embedded auth widget - you'll need to set the name of your application in the JavaScript - or you can copy the JavaScript tag into a page of your own.
There's also an example that does not use any Engage UI widgets in src/main/webapp/no-widget-example.jsp - you'll need to configure your application domain in that page.
The Java Servlet example in src/main/java/com/janrain/example/AuthInfo.java just serves as a destination for the user's browser to be redirected to after logging in, then it calls the auth_info API with that token and displays the results.
To compile and run, just run mvn jetty:run in the top level of the project, assuming you Maven installed. This example uses the servlet-api and commons-io.
