  <p>Some commands I tried:</p>
  
  <pre><code>&gt;which java
  /opt/java/jdk1.7.0_79/bin/java
  
  &gt;$JAVA_HOME
  bash: /opt/java/jdk1.7.0_79
  
  &gt;javac
  Usage: javac &lt;options&gt; &lt;source files&gt;...
  </code></pre>
  
  <p>In the node-java package, when I execute: "node findJavaHome.js" I get "/opt/java/jdk1.7.0_79"</p>
