title: Global object in Grails
body: <p>Writing a small web-app in Grails I encountered a problem with global objects. I have a class which runs threads - ExecutorService with queuing. </p>
  
  <p>The problem is where to create an object of this class, to have it available in Controller? </p>
  
  <p>I've tried at init (BootStrap) but there's no chance then of getting its instance anywhere else.</p>
  
  <p>In general - what I need is an object in one single instance for whole application, with access from Model and/or Controller.</p>
