title: Where is javac after installing new openjdk?
body: <p>An additional jdk was installed and configured on RHEL5.</p>
  
  <pre><code>yum install java-1.7.0-openjdk.x86_64
  update-alternatives
  </code></pre>
  
  <p>It appeared to work: <code>java -version</code> points to desired 1.7.</p>
  
  <p>However, <code>javac -version</code> still points to old 1.6.</p>
  
  <p><code>sudo update-alternatives --config javac</code> only lists one option.  I could not find the additional <code>javac</code>.</p>
  
  <p>How do I install or configure a 1.7 <code>javac</code>?</p>
