I installed Processing 2.2.1 (linux) on the RasPi (running Debian Wheezy) to connect a USB-Webcam and capture video stream with the standart processing.video* library. When I try to run the program (from processing window or exported) I get the following error:
NoClassDefFoundError: Could not initialize class com.sun.jna.Native
After searching the web for several days I found and tried following solutions, wich did not change anything:
Install gStreamer 0.10 package (as seen here)
Update to the latest Java Version which is:
java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b108)
Java HotSpot(TM) Client VM (build 25.0-b50, mixed mode)
install JNA 4.0.0 (reference here)
after it still resulting in the same error, I am not really shure what to try next since I am also more or less a beginner when it comes to the RaspberryPi and Java.
Any Tips/Hints are highly appreciated!
