title: How do I compile a java file that has jar dependencies?
body: <p>I have a helper lib that I wrote to sit on top of Apache Commons, and when I try to javac it (so that I can make it into a jar) it complains, quite reasonably, that it has no idea what I'm talking about when I make reference to the stuff that's in the commons.jar.</p>
  
  <p>How does one include a jar so as that javac can compile?</p>
