Strange Trouble (not an issue but i can't work with your wonderful API)

Hi,
First of all my compliment for your job: really great!!

I'm making a sub rover with raspberry PI P4 64 bit and I really need to implement a cam system to drive it and watch where it is. Unfortunately I find e problem using slog4j because every time I try (in my software) Webcam webcam = Webcam.getDefault() I get a very strange exception don't have anything to do with your software but prevent me to go ahed:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: ch/qos/logback/core/joran/spi/JoranException

Have you notice of something like that? I imported on my netbeans project all available library on the net so far but I didn't solve the issue.

Thanks so much in advance and best regards,
Davide

You project is not mananged by maven, so the slf4j and dedefault logback logger IMPL are missing, please copy coresponding jars to your classpath. ti should work out.
