title: adding ressources and services code to a Jlink image
body: <p>now suppose you have an application that let (advanced) users write ressource files and compile service code (from templates)</p>
  
  <p>before Java 9 I did that with two different jars: one was theApp.jar and the other theAdppDeploy.jar the later being generated on site from templates.</p>
  
  <p>with the modular system it still could be done (though we will have cross-dependencies across modules)</p>
  
  <p>but is it possible to think about a JImage generated by Jlink and having the (advanced) user toy with this image by adding ressource files and service code?
  How to do that (if possible)?</p>
  
  <p>thanks</p>
