Accessing serial ports using Java

On Linux Mint 14 (based on Ubuntu 12.10), here is how I configured Eclipse so that I can access PC's serial ports:

  • install package librxtx-java (version 2.2pre2-11)
  • in Eclipse, for concerned project:
    • create folder lib at the root of the project
    • copy files /usr/share/java/RXTXcomm-2.2pre2.jar and /usr/lib/jni/ into it
    • create links to these two files, without version numbers (RXTXcomm.jar and
    • add RXTXcomm.jar to the project build path, as an external JAR
