RXTX java.lang.UnsatisfiedLinkError Exception

RaspberryPiMan · Tue Jul 22, 2014 7:32 pm

Hello everyone..,

I'm following this tutorial:
http://www.drdobbs.com/jvm/control-an-a ... /240163864

which has a simple modification on the code published on arduino playground:
http://playground.arduino.cc/interfacing/java

However, I am still getting this error:

Code: Select all

java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" 
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path

C:\Users\ABDY\Documents\NetBeansProjects\JavaEmbeddedRaspberry\nbproject\remote-platform-impl.xml:57: Remote command failed with exit status 1
BUILD FAILED (total time: 5 seconds)

On the Raspberry pi, I made sure that I have librxtxSerial.so inside /usr/lib/jni and a RXTXcomm.jar inside /usr/share/java/RXTXcomm.jar.
but the error still appear
On my host PC, i checked the remote platform configuration on NetBeans IDE:
1- Java.Class.Path = org-netbeans-modules-java-j2seembedded-probe.jar
2- Java.Library.Path = /usr/java/packages/lib/arm:/lib:/usr/lib

I will appreciate any help of how to setup RXTX Library to work correctly with java SE Embedded.
Help please!!!
