title: Ant error when trying to build file, can't find tools.jar?
body: <p>When I run ant it says:</p>
  
  <pre><code>Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar
  Buildfile: build.xml does not exist!
  Build failed
  </code></pre>
  
  <p>What package can I use to download the file required > C:\Program Files\Java\jre6\lib\tools.jar</p>
  
  <p>I just downloaded this one:</p>
  
  <blockquote>
    <p>jre-6u19-windows-i586-s.exe</p>
  </blockquote>
  
  <p>but unfortunately it appears that it was not on it...</p>
