Problems with native libraries on UDOO

Hello, i've tried multiple projects with external Jars and natives.
Everytime i try to launch, I get unsatisfiedlink errors,

I try to use the -Djava.library.path option and it is not working... i also tried to create runnable jars, fat jar but i'm always getting this error.
I've also tried to do:

Code:

static{
		try
		{
			System.load("test_lib/librxtxSerial.so");	
		}catch(UnsatisfiedLinkError e)
		{
			e.printStackTrace();
			System.exit(1);
		}

Directly in the main class, but no success... Anyone have a solution or any hint ? Thanks

It's working perfectly fine on a ubuntu PC..

 

i have same problem HELP ME!!!

 

What is the stack trace - an FNF kind of msg maybe ?

Have never used these pkgs... but presuming you used steps similar to those in here:

What is the -D setting you are using ?

installing lib with terminal

Code:

sudo apt-get install librxtx-java

After doing this, the libs should be in /usr/lib/jni
Now just run the jar and tell the JVM to look in this folder for the library

Code:

java -Djava.library.path=/usr/lib/jni -jar FileName.jar 

Sucess!
thx for help
