Arduino Serial Communication from Java

I can't serial the port JAVA to Arduino ..
I Get this error

MY Libraries all

You need to have have the native library installed on your machine: http://rxtx.qbang.org/wiki/index.php/Download

Link to it in Eclipse: Project -> Properties -> Java Build Path -> Libraries -> RXTXcomm -> Native library location
