Java Programming

Hi,

I'v been reading this posting [http://forum.java.sun.com/thread.jspa?forumID=31&threadID=699276] about how to achieve running a bash script from a java application, but I didn't get it working. Currently my code is

@Action(block = Task.BlockingScope.ACTION)
public void executeTestGenerator() {
	File workDir = new File("c:/cygwin/bin");
        String[] cmdArray = new String[5];
        
	cmdArray[0] = "c:/cygwin/bin/bash";
        cmdArray[1] = "--login";
        cmdArray[2] = "-i";
        cmdArray[3] = "-c";
        cmdArray[4] = "/cygdrive/c/temp/dwhim";
		      
	try {
		Runtime.getRuntime().exec(cmdArray, null, workDir);
		System.out.println("Executing cmd");
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}

But nothing happens when I invoke this method. Has anybody an idea how to get this working?
