There should be no need to manually install JNA. OpenSUSE already provides JNA 
and it works fine (I compiled and ran an example that uses it and it worked).

JNA patch for SUSE is "/usr/share/java/jna.jar" and 
"/usr/share/java/platform.jar". I don't know if it's the same for Ubuntu.

I have the same issue with SVN rev 476. Is WCS incompatible with OpenJDK 6, 
perhaps?

Same problem on Fedora 18 x64. Installed jna package manually, even softlinked 
jna.jar into webcamstudio/libraries folder, no immediate difference.

Adding "Class-Path: /usr/share/java/jna.jar" to the manifest.mf and rebuilding 
has allowed it to find JNA, but then it just has another NoClassDefFoundError 
on something else. Further adding "../libraries/AbsoluteLayout-7.0.jar" to that 
Class-Path allowed the program to actually start.

It seems that, by default, the WebcamStudio.jar is just completely unaware of 
the libraries folder, and no external changing of the classpath can change that 
- it MUST be edited in the manifest.mf. (Note: Directing Class-Path to the 
included jna-3.2.7.jar has a different and unrelated error; Fedora jna package 
is at 3.4.0-5.)

I also had to add all the libraries to manifest.mf and "ant clean jar" again to 
make 0.61 work.

This problem still seems to exist with the latest SVN version, adding the 
Class-Path line fixed it for me.
