I am attempting to setup JavaPOS on a Linux machine and am not having any success. I have installed:
rxtx
*.so -> JAVA_HOME/jre/lib/amd64
*.jar -> JAVA_HOME/jre/lib/ext
com api
comm.jar -> JAVA_HOME/jre/lib/ext
javax.comm.properties JAVA_HOME/lib
When I attempt to load the device, I am getting a JPos Exception "Service does not exist".
