I am new to Processing and attempting to write code to communicate with my Arduino - on a linux platform.

When I run the following code:

println(Serial.list());

I'm supposed to get a list of available ports through which communication with Arduinos/computer is/are possible but instead I get the following message:

WARNING: RXTX Version mismatch
Jar version = RXTX-2.2pre1
native lib Version = RXTX-2.2pre2

I don't know anything about Processing nor why this message is coming up ... I really need help.

I found this helpful link which leverages the Arduino's RXTX solution to resolve the same issue for processing.

Having followed the instructions, my warning message is gone and I now get available port information delivered to my application.

    \$\begingroup\$ please rewrite the solution here, rather than linking to it. I should have done the same thing. Reason being that the page might change or dissappear. From what I can tell, the thing with the stack exchange sites is to put the answer on the site so people dont have to go elsewhere. \$\endgroup\$ – geometrikal Aug 14 '12 at 22:24
