Bat File execution Problem in Win Server 2k3

Question

I have a jar that is calling a .bat file.
It executes the bat file in Windows XP, and Windows 2000
But when I run it in Win Server 2k3 it can't execute.
I get Exit Value 1
Does anyone know any differences between the Operating Systems that could cause this?
Thanks
Paul

Answer 1

I don't know enough about the difference in system or even between your two installation. An exit 1 error could happen for any reason, such the batch file not being found or other reason.
The best thing to do is get a handle to the stderr and stdout of the process and display them. To do this you would write a class that reads from an InputStream (the output of the process is read using an InputStream) and displays to System.out. Follows is some code that illustrates this (done off the top of my head, more or less, so it won't necessarily execute as is):
   void runExternalTask()
      String cmd = new String { "myexecutable.exe" };
      Process proc = Runtime.getRuntime().exec(cmd);
      ProcessOutputHandler procOut = new ProcessOutputHandler(proc.getInputStream(),0);
      ProcessOutputHandler procErr= new ProcessOutputHandler(proc.getErrorStream(),0);
   public static class ProcessOutputHandler implements Runnable {
        InputStream _in;
        //PrintStream _out;
        boolean run = true;
         * Constructor for ProcessOutputHandler.
        public ProcessOutputHandler( InputStream in, int procID ) {
            _in = in;
            (new Thread(this,"output.handler."+procID)).start();
        public void close () {
            run = false;
        public void run() {
            try {
                int i = 0;
                while ( run && (i=_in.read()) != -1 ) {
                    System.out.print((char)i);
            } catch (IOException e) {
              e.printStackTrace(System.err);
    }
