title: Having trouble running code in Eclipse using JOGL
body: <p>I'm trying to run an application in eclipse which is setup as MVC app and it is the solution code posted by our professor for a homework. After I copy and pasted all of the classes and tried to run it, I got the following error: </p>
  
  <h2>JOGL> Hello JOAL Exception in thread "main" java.lang.NoClassDefFoundError: com/jogamp/openal/JoalVersion at jogamp.opengl.openal.av.ALDummyUsage.main(ALDummyUsage.java:14) Caused by: java.lang.ClassNotFoundException: com.jogamp.openal.JoalVersion at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 1 more</h2>
  
  <p>I'm not entirely sure what the issue is and apparently no one else has been having the same issue. </p>
  
  <p>My buildpath has a library I titled "JOGL" and I added the external jars gluegen-rt.jar and jogl-all.jar as was instructed by the professor.</p>
  
  <p>Thanks for the help!</p>
