I used to be able to scan with your plugin in linux using Marcel Austenfeld's
Scan plugin
http://rsbweb.nih.gov/ij/plugins/twain-scan.html
and using the
library
uk.co,mmscomputing.device.sane.jar

But now I get this
error:

JarLib.load
        Error

Any ideas ?
The
file not found is right there in the jar file
called
uk.co,mmscomputing.device.sane.jar
under

uk/co/mmscomputing/device/sane/lin32/libjsane.so

I am running opensuse
linux x86_64 bits. Could that be a problem?

I tried emailing Marcel
directly, but the email address bounces.

Regards
