HI,

I keep getting this error when trying to communicate to arduino via serial:

Error inside Serial.ports()


java.lang.UnsatisfiedLinkError: /home/matjaz/Clairvision/Project_Signal/Processing/Processing_software/processing-1.2.1/libraries/serial/library/librxtxSerial.so: /home/matjaz/Clairvision/Project_Signal/Processing/Processing_software/processing-1.2.1/libraries/serial/library/librxtxSerial.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) thrown while loading gnu.io.RXTXCommDriver

Confiuration::
Ubuntu 10.10., 64 bit
Sun java 6
64 bit arduino 0021, Processing 1.2.1

Other threads indicate problem in arduino's java rxtx libraries. I have replaced them but still keep getting this error.
Used this links:
http://chemicaloliver.net/arduino/fixing-arduino-on-ubuntu-9-10-karmic-x64/
http://myy.haaga-helia.fi/~karte/arduino_editor_on_64_bit_ubuntu_gutsy.html

Any clues? I'm in a need to make it work...

Thanks.
