Good Day,

     I have created my own program using the v4l4j API. When I'm running the program in eclipse it works fine, but after making the project to a .jar and tried to run it using
the terminal, the "Cant load v4l4j JNI library" error comes out.

Thank you for your time.

Do you have the "lib" folder, where there is the "v4l4j.jar" file, in the same position of your program's jar file?

Hi there,
can you tell me the full path to:
- libv4l4j.so
- libvideo.so
- v4l4j.jar
- your app's jar file

Also what is the exact command you use to run your app.
Thanks
Gilles

I tried that but still didn't work.
I tried it in my Ubuntu and it works fine, but when I do the same in my CentOS the error keeps on coming out.

What command do you use to run your app ?

Can you try to run this:
java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/v4l4j.jar au.edu.jcu.v4l4j.examples.DumpInfo
and post  the output

also run this:
ldd /usr/lib/jni/libv4l4j.so
and post the output

First i just tried "java -jar myjar.jar" then I also tried "java -jar myjar.jar -Djava.library.path=/usr/lib/java -cp /usr/share/java/v4l4j.jar".

Try using java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/v4l4j.jar -jar myjar.jar instead. it will work.
