Finally, we've come to the fun part of the tutorial: learning by doing. We'll start by running the comprehensive JAASExample application, which contains all of the authentication and authorization mechanisms (and code) we've worked with throughout the tutorial. After running the example and seeing the results of our first configuration, we'll explore some different configuration options, checking the results as we go along. At the end of this final section of the tutorial, you'll have had your first taste of programming in JAAS.
