hi,
i would like to connect my arduino with processing. first i got an RXTX Native & Java lib Version mismatch-error. so i updated my libraries - works fine, i think.

but finally i got a (new) error:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

i read http://processing.org/discourse/yabb2/YaBB.pl?board=Electronics;action=display;num=1193459849, there were similar problems in the mac snow leopard os. The error here was occurred becouse something was wrong with the access-premissions for uucp_lock() (/var/lock/). I dont reseve specifically this error but the following error message is the same (even there is no /var/lock folder anymore on OSX Lion) . To summarize, I have no idea where the error lies , because I can not get a helpful error message (gnu.io.PortInUseException = inaccurate).

Iam using Processing 1.5.1 | Mac OSX Lion 10.7.2.

PleasehHelp me, i realy like to talk to my arduino....

best,

jo.
