title: How to add/reference .jar files in your project when you don't have an IDE
body: <p>I am new to Java (basically a LAMP developer). I got this JAVA API to parse <code>.pst</code> files and show all the inbox messages. </p>
  
  <p>I tried executing a given <code>.class</code> file but it throws exceptions. I need to add/reference some <code>.jar</code> files provided by the API.</p>
  
  <p>I don't have any IDE for Java yet. <a href="http://www.wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-%28Java%29" rel="nofollow noreferrer">Wikihow</a> says</p>
  
  <blockquote>
    <p>When your Java project requires JAR
    libraries to function, you have to
    configure your project to include the
    libraries in its build path.
    Fortunately, Eclipse makes this
    process simple and easy to remember.
    The build used here is Eclipse Java -
    Ganymede 3.4.0.</p>
  </blockquote>
  
  <p>So, what configuration do I have to do? Or is it better to get Eclipse IDE? I just have a single <code>.class</code> file to be executed. </p>
