Problem mit runtime und Buttons unter Windows

Grünschnabel
Hallo,

nachdem mein SWT Problem hier gut gelöst wurde hoffe ich auch jetzt auf Antworten...

Ich hab eine Klasse die das Programm (konsolen tool) aufruft. Diese Klasse bzw. die Methoden werden wiederum von einer VC aufgerufen (per Button).

Unter linux gehts prima.

Unter Windows bleibt der Button gedrückt bis zur Ewigkeit...(anscheinend kommt der Aufruf nicht zurück)

Hier mal der code der avrdude.java
Code: 
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Vector;


public class avrdude {
	private String avr;
	private String promer;
	private String datei;
	private String port;
	private String memtype;
	private char operation;
	private char format;
	private String aktion;
	private String os;
	
	public avrdude() {
		avr="";
		promer="";
		datei="";
		port="";
		memtype="";
		operation=' ';
		aktion="";
		format='i';
		
		os= System.getProperty("os.name").toLowerCase();
		}
	
	public String execute() {
		Process proc=null;
		baueaktion();
		String ausgabe=aktion;
		
		try {
			if(os.startsWith("windows"))
				proc = Runtime.getRuntime().exec("cmd /u /c "+aktion);
			else if (os.startsWith("linux"))
				proc = Runtime.getRuntime().exec(aktion);
			
			BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
			BufferedReader error = new BufferedReader(new InputStreamReader(proc.getErrorStream()));
			
			String zeile;
			while ((zeile = input.readLine()) != null) {
				ausgabe+=("\n"+zeile);
			}
			while ((zeile = error.readLine()) != null) {
				ausgabe+=("\n"+zeile);
			}
			
		} catch (IOException e1) {
			e1.printStackTrace();
		}
		return ausgabe;
	}
	
	public String execute(String argument) {

Was ist da im argen? Der befehl wird anscheindend ausgeführt weil eine Datei mit passender Grösse entsteht. Das Aufrufen geht auch gut wenns ohne Button passiert. (zu Anfang wird die Methode getpromerliste() (genauso wie getavrliste() )aufgerufen die gehen.
 
hab jetzt mal probiert die Klasse processBuilder zu nutzen nur beim Eintippen vom Code
Code: 
proc =new ProcessBuilder("ls").start();

sagt Eclipse "Der Konstruktor ProcessBuilder(String) ist nicht definiert (undefined)"

hab oben import java.io.*; stehen...

und nun?
 
Das mit dem ProcessBuilder geht jetzt...

build = new ProcessBuilder(new String[] {"prog","argument"});

so muss das heissen....

bzw.

proc = new ProcessBuilder(new String[] {"",""}).start();

Nur wie kann ich jetzt aus meinem String mit lauter Argumenten einen String[] machen indem dannn die Argumente drin stehen?

EDIT:
da geht mit split(" ");
