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?

[Anonymous]

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.

Originally posted by: zejda...@gmail.com

Same with me, had to add Class-Path: ../libraries/AbsoluteLayout-7.0.jar ../libraries/AppFramework-1.03.jar ../libraries/commons-cli-1.2.jar ../libraries/commons-codec-1.6.jar ../libraries/commons-httpclient-3.1.jar ../libraries/commons-io-2.2.jar ../libraries/commons-lang3-3.1.jar ../libraries/jcl-over-slf4j-1.6.5.jar ../libraries/jffmpeg-1.1.0.jar ../libraries/jna-platform-3.2.7.jar ../libraries/jna-3.2.7.jar ../libraries/jsr305-0.1~+svn49.jar ../libraries/jtwitter.jar ../libraries/log4j-1.2.16.jar ../libraries/mail.jar ../libraries/netty-3.2.6.Final.jar ../libraries/slf4j-api-1.6.5.jar ../libraries/slf4j-log4j12-1.6.5.jar ../libraries/swing-worker-1.1.jar ../libraries/zxing-core.jar ../libraries/zxing-javase.jar to manifest.ml

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