title: Play 2.0 IOException
body: <p>I've just installed play-2.0 and keep getting the following error when I try run any of the sample apps:</p>
  
  <pre><code>IOException: Cannot run program "javac": java.io.IOException: error=2, No such file or directory
  </code></pre>
  
  <p>I've tried on ubuntu 11.10 installing play via the typesafe stack and on crunchbang 10 by downloading the zip from the website. Both times I get the same error?</p>
  
  <p>What am I missing?</p>
