title: Basic Openxava examples
body: <p>Looked at some applications built using Openxava and it seems like a very useful peice of kit. However I am trying to find a very basic worked example ( helloworld type ) but can't find any.  I have looked at the Openxava bundled examples but even these have too much 'magic' going on in them where the only thing you code is a single Entity class and next step is viewing a working Web Application.  How is the UI created??<br>
  I'm looking a simple example like where I have a simple business class with a single method that returns a "helloWorld" string,  how do I display that as the text on a button on a web page?</p>
