Error : How to execute *.BAT file

Question

Some of the friend said me to execute any file following code
Runtime rt=Runtime.getRuntime();
Process pr=null;
pr = rt.exec("cmd.exe /c start " + "myfilename");
I get error as
CreateProcess: cmd.exe /c start myfilename error=0
Press any key to continue . . .

Thanks..

hi Bhavin
try this code because i had the same problem an d this thing works for me here is the code
    // Get file name
    String File_Name = // What ever yr file name get as String
    // Get Operating System Name
    String os_name = System.getProperty("os.name");
    os_name = os_name.toUpperCase();
    // Declare command as array of string
    String[] command ;
    // on Windows XP, NT, 2000 command is different and on win 98, 95 is different
    if(os_name.indexOf("XP") != -1){
         command = new String[] {"cmd", "/C", "start", "\"\"", File_Name};
    else if(os_name.indexOf("NT") != -1){
         command =new String[] {"cmd", "/C", "start", "\"\"", File_Name};
    else if(os_name.indexOf("2000") != -1){
         command = new String[] {"cmd", "/C", "start", "\"\"", File_Name};
    else  {
         command = new String[] {"start", "\"\"", File_Name};
    try
        // Run the commands using Runtime
        Process process = Runtime.getRuntime().exec(command);
    catch(IOException ioe)
        //show Error message
              JOptionPane.showMessageDialog((Component) null,
                                      "Unable to Locate the file..."+
                                      "\n"+ioe.getMessage(),
                                      "Error...",
                                      JOptionPane.ERROR_MESSAGE);
    }Regards
