Hello everybody,

I created a Form Application in Java to communicate via USB to a Microcontroller board. For that I need a library called libusbJava. My program is working just fine on NetBeans, but when I try to run the Jar file I receive the following error:

Caused by: java.lang.ClassNotFoundException: ch.ntb.usb.LibusbJava

When I build the jar file I receive the following notes:

Note: C:\Users\Home\Desktop\Thesis\Java UDP\USBDriver\src\ uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Not copying library C:\Users\Home\Documents\NetBeansProjects\UCEcho\libusbJava , it's a directory.

I am not very familiar with java. Does anybody knows what I have to do?

Thanks very much,
