title: println in grails gsp file
body: <p>I know this is simple thing, but i was not aware.</p>
  
  <p>I used println in gsp file and expected to print output in console. But this is showing on page.</p>
  
  <pre><code>&lt;% 
  for(int i =0; i &lt; threads.size();i++) {
       println i
  } 
  %&gt;
  </code></pre>
  
  <p>thanks.</p>
