String index out of bounds?

Question

hi, i am writing a java program which reads in a file and then error checks it, once its done this it will output it to another file.
It was working fine until i tried writing another method, now it keeps telling there is a string index out of bounds exception with the 'charAt' method. I have uploaded all the necessary files to compile and run the program.
I am unsure of what the problem is so id be grateful of you would be able to check it out. If it helps i programmed and compiled this problem in netbeans 3.6.
I uploaded it here: http://www.megaupload.com/?d=45QHZYN1
you have to wait 45 seconds, the timer is in the right hand corner before you can begin download

try
      {   System.out.println("2");
          Properties props   = new Properties();
          File file          = new File(System.getProperty("user.home") + File.separator + configFileName);
          BufferedInputStream bis = new BufferedInputStream(new FileInputStream (file));
          props.load(bis);
          if(bis != null)
              bis.close();
          // Load the information from the properties file.
          String driver = (String)props.get("DB_DRIVER");
          String user    = (String)props.get("DB_USERNAME");
          String passwd  = (String)props.get("DB_PASSWORD");
          String url     = (String)props.get("DB_URL");
          conManager = ConnectionManager.getInstance(driver, user, passwd, url);
logFilename = fileName.substring(0,fileName.lastIndexOf(".")) + ".log";
          System.out.println("log file name :: " + logFilename);
          fout = new FileOutputStream(new File(logFilename));
     catch (Exception e)
         e.printStackTrace();
  public static void main(String[] args)
    FormsRefresher formsRefresher = new FormsRefresher();
    String filename = "D:\\FCC\\FMB\\CLDUDCMT.fmb";   
    String username ="BPELDEMO";
    String pwd = "BPELDEMO";
    String url = "jdbc:oracle:thin:@PLUTO:1521:seriousim";
    String filename = args[8];
    formsRefresher.initialize(filename);
    formsRefresher.processForm(filename);
}I am getting the error in the lines quoted bold
This is the code and i am getting another error also along with that.
That is Unsatisfiedlink error
