title: Talend runtime config file
body: <p>I publish a RESTful webservice with Talend ESB and want to run it in the Talend runtime. 
  As I want to use some variables from my own custom config file. I.e. database credentials etc.</p>
  
  <p>This file should be external fro the OSGI deploy file to get modified after compilation.</p>
  
  <p>Where could I place this file and how would I reference it in the Talend job design?</p>
