    Default Validation for SpecialCharacter

    if (firstName.equals("")) {
    errors.put("firstName", "Please enter your first name");
    firstName = "";
    allOk = false;
    } else {
    String expression1 = "^[!,@,#,$,%,^,&,*,(,)]+$";
    CharSequence inputStr1 = firstName;
    Pattern pattern1 = Pattern.compile(expression1);
    Matcher matcher1 = pattern1.matcher(inputStr1);

    if (matcher1.matches()) {
    allOk = true;
    } else {

    errors
    .put("firstName",
    "FirstName Should be Special Character");
    firstName = "";
    allOk = false;
    }
    }

    I don't know what you want to 'validate'...what special characters? Do you want - or not want them?
