Java and Darwin
I have a Java applet that runs on Mac OS X and the underlying Darwin interface. The applet makes the following system call:
Runtime.getRuntime().exec(
This system call works fine if there are no spaces in srcFile, but (of course) it doesn't work if there's a space. My problem is that when I put quotes around srcFile, like
Runtime.getRuntime().exec(
that doesn't work either. The ditto command creates destFile, but it's empty.
The problem isn't with the ditto command, because I can use Terminal and type
ditto -c -k --keepParent -rsrc "/Users/computer/Desktop/t
ditto -c -k --keepParent -rsrc '/Users/computer/Desktop/t
and both work as expected. Does anybody know what I'm doing wrong?
Thanks,
Jay

Does it work when there are *no* spaces?

OK here is what im testing and it works for me:

public class Main {
/** Creates a new instance of Main */
public Main() {
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
try {
String filename ="W:/Java/JavaApplication1
Runtime rt = Runtime.getRuntime();
final Process proc = rt.exec(
new String[] {
"cmd.exe",
"/c",
"\"\""+filename+"\"\""
}
);
} catch(Throwable cause) {
}
}
}

Yes, it works correctly when there are no spaces. I'm going to try the exec command with the String array parameter and report back.

The overloaded exec command worked. Thanks.
