I installed the mysql-connector dependency using Maven and added a few more lines to my Main class to instantiate the MySQL driver and set up the connection details: We provide a set of command line flags to customize generation, and a configurable function to generate the code: It may include specifications for routines, data structures, object classes and protocols used to communicate between the consumer and implementer of the API.

But we can use these types in more advanced ways, to have multiple listings or identify a single resource in multiple ways. In this tutorial I'll show how to run the API in happstack, but the code for other frameworks is very similar.
