Hi In my spring webapp I have a password variable which I want to be at least 0 characters or more than 6 and less than 20. I know that there is annotation:
but I have no idea how to add possibility that password can be 0 characters. Will somebody help me with this? You want either empty password or 6 to 20 chars lenght, correct? Are you using hibernate-validator in Spring MVC Controller?
