A 30 second search and I've hundreds of examples of how to do this via: Curl, Perl, Python, PhP, ... but nothing for Java. There's just a lot of noise from bodies having problems getting any of the numerous SSL implementations to work.
So wondering is there a from scratch walkthrough that covers the Maven tweaks (or at least the imports) needed to get a working set of dependencies, and enough detail to cover the basics (working code sample) to uses the bundled Java Truststore to say pull one JSON object, over a properly signed connection.
