JOGL Web Start demos not working on Mac (Snow Leopard)

Hi,

Just been trying to run the Java Web Start demos on http://jogamp.org/jogl-demos/www/ but I get the following exception:

java.lang.UnsatisfiedLinkError: com.jogamp.common.jvm.JVMUtil.initialize(Ljava/nio/ByteBuffer;)Z

Strange -- I just ran the Gears demo on a MacBook Air (Snow Leopard), and it works fine (though some of the others have problems). Are you running it directly from the JogAmp web site, or did you download it to run on your own web site? The UnsatisfiedLinkError usually means a JOGL native library is missing or its version is mismatched with the JAR file.

Directly from the JogAmp site, on the page I linked to.

Ah not to worry; I had some stray local versions of the libraries linked through my environment. Cleared those out and it runs fine.

Thanks for your speedy response though

Avoid putting JARs directly in the JVM. Maybe you did this, it is only a supposition.

There's also the Web Start cache, which you can clear with "javaws -Xclearcache". Some other users have seen a problem with this (see https://jogamp.org/bugzilla/show_bug.cgi?id=470).
