problems with exec("rundll32.exe shell32.dll...")

hi,
 thanks but this hasn't worked either - in fact passing any file as the
arg[0] makes no difference(!), I don't think its even getting that far
(altered the code to as below)
I don't understand exactly how this could be going wrong, unless maybe "_"
is somehow munged by Runtime.exec?
thanks,

import java.io.*;
import java.util.*;
public class GCJTest {
 public static void main(String [] arg) throws Exception {
 String filename = new File(arg[0]).getAbsolutePath();
 // can't use 1.4 String.replaceAll
 //filename = filename.replaceAll("\\\\","\\\\\\\\"); // replace
\ with \\
 String result = "", tok ="";
 for(StringTokenizer st = new
StringTokenizer(filename,"\\",true); st.hasMoreTokens(); )
 result+= (tok= st.nextToken()).equals("\\") ? "\\\\" :
tok;
 System.out.println(filename+" to "+result);
 Runtime.getRuntime().exec("rundll32.exe shell32.dll
ShellExec_RunDLL "+result);
 }
}
