no usbJava in java.library.path

Question

I got a .jar file from a code that works on Windows, and I'm trying to run it on Linux, but I keep getting this message, and don't know what to do.

    Exception in thread "Thread-0" java.lang.UnsatisfiedLinkError: no usbJava in java.library.path

I'm using the Java wrapper for the libusb-0.1 (I followed the installation instructions here ).

Any help would be really appreciated!

You need to create a link to the shared library, as per the Linux installation instructions:

http://libusbjava.sourceforge.net/wp/?page_id=8

If you're having trouble building the shared library this might be of some help:

The sources for the library itself is under /libusbjava/trunk/LibusbJava/ in the SVN source tree.
