Hello all,

I am trying to create a basic screen capture program with Java and Processing, however I am coming across the following exceptions when attempting to run the program:

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: quicktime/std/StdQTException

at Camera.setup(Camera.java:38)

at processing.core.PApplet.handleDraw(Unknown Source)

at processing.core.PApplet.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Caused by: java.lang.ClassNotFoundException: quicktime.std.StdQTException

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)

... 4 more

Here is the code that produced said exceptions. Any help would be greatly appreciated! Thanks, Mike
