I cannot instantiate a serial connection. The same code works with a Main Class as a plan java application.
I made the following changes in the openHAB2 runtime:
VM Arguments:
-Djava.library.path=/usr/lib/jni/ -cp /usr/share/java/RXTXcomm.jar
This works on my 64Bit Linux and the raspberry pi in the same way.
When I call
CommPort commPort = portIdentifier.open(“waschapp”, 2000);
I get the following exception:
