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
