title: JasperReports plugin for Grails: Getting "No such report spec" Exception
body: <p>I am testing the jaspergrails plugin for Grails.
  I am following the tutorial for this plugin. I've created a trivial
  jasper report and I've put it under web-app\plugins\jasper-0.9.5\reports\all-races.jasper</p>
  
  <p>I am getting an exception</p>
  
  <p><strong>Error 500: java.lang.Exception: No such report spec: reports\all-races.jasper or .jrxml</strong></p>
  
  <p>Any hint why?</p>
  
  <p>thanks a lot in advance.</p>
  
  <p>Luis </p>
