Loading library from external jar

Hi Stefan,
Thanks for your quick reply! You were right with the RXTX/JNI Problem, having rxtx installed it worked for me executing OpenEMS as a jar with the argument -Djava.library.path=/usr/lib/jni (on linux).

I found a workaround that allows me to start it in Eclipse, too, which wasn’t possible before (https://stackoverflow.com/questions/10751304/java-lang-unsatisfiedlinkerror-no-rxtxserial-in-java-library-path-thrown-while if someone has similar problems) so that’s fine for me now. Just in general though, how would you add a system property as an argument if you want to start through Eclipse?

Greetings, Erik
