Running Processing Sketch through Java on Mac

[Melanie Moeller]

Hi everyone,

I have written this code to open and run a Processing (.pde file) sketch. So far, it opens the sketch, but it does not run it. The Processing keyboard shortcut for running a sketch is ⌘R. Any suggestions how I can get Java to start executing the sketch?

Thanks a lot!!

This is my code:

package javaapplication;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class max {

private static Process child1;

public static void main (String[] args) throws IOException {
String s;
try {
Process p = Runtime.getRuntime().exec(
"/usr/bin/open file:///Users/Documents/InteractiveSystem/processingfile/processingfile.pde");
BufferedReader err = new BufferedReader (
new InputStreamReader (p.getErrorStream()));
while ((s = err.readLine()) != null) {
System.out.println(s);
}
}
catch (Exception e) {
e.printStackTrace();
}
try{
String command = "⌘R";
child1 = Runtime.getRuntime().exec(command);
command = "⌘R";
child1 = Runtime.getRuntime().exec(command);
} catch (IOException e) {
}
}

void RunProcess(){
start();
}

private void start() {
// TODO Auto-generated method stub

}
public void run() {
try{
Process run = Runtime.getRuntime().exec("/usr/bin/run file:///Users/Documents/InteractiveSystem/processingfile/processingfile.pde");
}
catch(Exception ex){
char[] s = null;
System.out.println(s);
}
}
}
