how to set java library path for processing

Question

I'm using PDE to run a Processing sketch, and I get the following error:

Verify that the java.library.path property is correctly set.

Could anyone of you tell me how to solve this problem?

Answer 1

You can set it on the command line thus:

java -Djava.library.path=...

and point it to the directory containing the relevant library.

Answer 2

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"

Answer 3

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

Answer 4

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.

Answer 5

Conclustion of above all answers (short form) is as follows:

Lets say my lib folder path is lib/

Then to add in the library path: run below command:

java -Djava.library.path=lib/ -jar  mySampleJar.jar
