title: NoClassDefFoundError when trying to run JAR which uses Absolute Layout
body: <p>I have developed a swing GUI for my program using the NetBeans form editor. I used the AbsoluteLayout so that I could click and drag components to wherever I needed them to go on the frame. The problem is that when I try to run the executable JAR file that I made for the program, I get the following error:</p>
  <blockquote>
  <p>java.lang.NoClassDefFoundError:
  org/netbeans/lib/awtextra/AbsoluteLayout ...Exception in thread &quot;main&quot;</p>
  </blockquote>
  <p>All of the GUI code was written for me by NetBeans so I'm not sure what the problem is here.</p>
  <p>I really like using the form editor because getting GUI's to look like I want them to is extremely tedious when I try to hard-code it myself. The program needs to be used for JavaWebStart and so it has to be in a working executable JAR file.</p>
