title: JPL/SWI Prolog not working
body: <p>I'm trying to use the SWI-Prolog JPL library, but I'm having problems.</p>
  
  <p>I'm trying to let my Eclipse project access JPL, but when I try to start the program, I get the following error:</p>
  
  <pre><code>Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no jpl in java.library.path
  </code></pre>
  
  <p>I copied the jpl.jar into my project directory, and I set it on the build path. Additionally, I pass the following VM arguments:</p>
  
  <pre><code>-Djava.library.path="C:\Program Files\Prolog\bin"
  </code></pre>
  
  <p>(That's the directory where Prolog was installed).</p>
  
  <p>What am I doing wrong?</p>

  <p>EDIT: I don't seem to have the libpl.dll anywhere on my computer. Could this be causing my problem?</p>
