Hi!

I'm trying to set up the serial communication with the arduino through processing.

My arduino is already working with the arduino IDE but I haven't managed in the Processing one.
However I didn't really understand what were the steps needed to set it up.

I'm using a Mac Intel so on the instruction page (http://processing.org/reference/libraries/serial/) the instruction aren't very explicit. All I understood was I didn't need to run the .command file

So what I did was:
1 - Setup the arduino
2 - Download processing and run one graphical example
3 - Using Arduino IDE upload to the board the standardFirmata example
4 - Close the Arduino IDE
5 - Open the SimpleWrite example in Processing
6 - Press play

What I got
Code:

Cannot run Java in 32 bit mode. Continuing in 64 bit mode.

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

gnu.io.PortInUseException: Unknown Application
	at ........
Exception in thread "Animation Thread" java.lang.RuntimeException: Error inside Serial.<init>()
	at ........ 

Did I miss anything in seting it up?


Edit: I'm thinking about submit this to bugzilla but I can't login for some reason, if anyone else thinks this is a good idea plase submit it and link it to this post.  

I have now changed the default version of Java do 6 and I no longer get the "Cannot run Java in 32 bit mode. Continuing in 64 bit mode." warning.

However this was not the (whole) problem for the serial  
I still get the PortInUseException.

I have now changed the firmata code since I understand there was some problems with it. But everything is the same  

Anymore ideas?
