Connect with RDP-client to VirtualBox Oracle Developer Day VM

This is more of a reminder for myself (so that next time I don’t have to go looking again)

On my Windows PC I use VirtualBox for running multiple virtual machines with all my Oracle stuff.

This weekend I downloaded and imported the latest “Database App Development VM” appliance, which at the time of writing contains Oracle 12.1.0.2 + APEX 5.0.3 + ORDS 3.0.3

This is the first part of a series of blog posts where I’ll share my knowledge on Page Designer internals I gained while working on the Xplug browser add-on.

Disclaimer: I’m not part of the APEX development team and there’s a lot of undocumented stuff. Most of my knowledge I acquired by trial and error and by looking at the APEX javascript source code.
I apologize in advance for any errors my blog posts may contain.
Perhaps some good advice first: don’t take anything for granted and always double-check yourself.

That being said, I’m a speaker at APEX Connect 2016 and the MVC-topic is part of a presentation I’m currently preparing for the Web Technologies track.  It’s called  “Lernen vom Page Designer – Auf den Spuren von Jules Vernes” .

Please bare with me. It’s going to be a rather long and somewhat theoretical blog post.  I’ll do my very best to keep it interesting.
