Error inside Serial.ports() in exported app
Aug 31st, 2009, 8:19am  
Hi all
The code below works when running in PDE
but when I export it as an application
I get the exception "Error inside Serial.ports()".
Using Processing 1.0.6 on OSX 10.5.8.

Any ideas as to why?

Code:

import processing.serial.*;

PFont myFont;

void setup() {
  size(500, 200);
  myFont = createFont("FFScala", 12);
}

void draw() {
  try {
    Serial.list();
    background(0, 255, 0);
  } catch (Exception e) {
    background(255, 0, 0);
    textFont(myFont);
    text(e.getMessage(), 20, 40); 
  }
}

BTW, the problems started with Snow Leopard which I recently installed. My Processing is 1.01. Help please!

Solved it! First, I had Processing 1.01. Installed the latest, 1.0.9, got different errors... Then realized I only have java1.6 (go to utilities->Java Preferences). Following this http://wiki.oneswarm.org/index.php/OS_X_10.6_Snow_Leopard procedure which restored Java1.5 (requires password,when you type it cannot be seen...jut type it and hit return), went back to Java Preferences and set things to java1.5 32 bit. Problem solved.

I'm having this problem with any serial communications from Processing.  I even tried using the SimpleWrite example and got the same error.  The line it highlights is "String portName = Serial.list()[0];" and the error says: "Error inside serial.ports()"  For some reason I can't copy the total error output, if anyone knows a way to fix that I'd appreciate that too.

I'm running Kubuntu 9.10 and I updated Java to the latest version.  I tried searching for this error, and everywhere I looked said to upgrade Processing.  I was already running the latest version, and I even tried upgrading to a Pre-Release version, to no avail.  No matter what I do, I keep getting the same error.  The problem doesn't occur under Windows Vista, but is constant under Linux.

Any ideas?
Thanks

Welcome back to playing this crazy game we love so much

You could wait until the new EP Generations comes out and see if challenges will be introduced again since well be getting memories back in that EP.  Itll be out May 31, 2011 here in North America so not too long to wait now
