Arduino Serial Communication from Java

Question

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

Load RxTx Windows 10

java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while

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
