Yeah, it occured to me that having the masterStringValidator code in my
original email would help, after I sent it... :) I just don't like
showing my code to people... they tend to cringe...
private String masterStringValidator(String property, String data, boolean trimIt)
throws NSValidation.ValidationException {
// Get the length values from the app properties
Integer minLength = new
Integer(Integer.parseInt(Application.properties.getProperty("VALIDATE_"+property+"MinLength")));
Integer maxLength = new
Integer(Integer.parseInt(Application.properties.getProperty("VALIDATE_"+property+"MaxLength")));
// Check if what we have is null
if (data == null) {
throw new
NSValidation.ValidationException(Application.properties.getProperty("VALIDATE_"+property+"NullError"));
}
// If requested, trim the data
if (trimIt == true) {
data.trim();
}
// Validate the length of the string
if ( (data.length() < minLength.intValue()) ||
(data.length() > maxLength.intValue()) ) {
throw new
NSValidation.ValidationException(Application.properties.getProperty("VALIDATE_"+property+"LengthError"));
}
// Check for illegal characters
// garbageDetect is another private method in the class, and
// works correctly.
if(garbageDetect(data,Application.properties.getProperty("VALIDATE_"+property+"Filter")) == true) {
throw new
NSValidation.ValidationException(Application.properties.getProperty("VALIDATE_"+property+"FilterError"));
}
// All done, return to sender
return data;
}
