how to set java library path for processing

Before System.loadLibrary(""), use the following code to check you java.library.path

System.out.println(System.getProperty("java.library.path"));

Generally, the java.library.path=/usr/java/packages/lib/i386:/usr/lib/jni:/lib:/usr/lib

Provides several options for:

• $ sudo cp libxxx.so /usr/lib/jni
• java -Djava.library.path=_path of so_ xxx

In Eclipse, I did this to get OpenCV working:

1. In the Run menu, select Run Configuration.
2. Go to the (x)=Arguments tab of your sketch.

3. Add this in the VM arguments field:

   -Djava.library.path="/path/to/OpenCV/library"
   

Your library.path is fine, what you need to do is to drop prefix lib and suffix .so from your System.loadLibrary( "..." ). On Linux or "linux-android" those will be automatically added by JVM.

You can set it on the command line thus:

java -Djava.library.path=... <existing arguments (classpath, name of class to run etc.)>

and point it to the directory containing the relevant library.
