Basically when we talk about validators we are probably talking about some component that validates configuration. So we may have DTD validator that makes sure a component conforms to a DTD or XSchemaValidator that makes sure it conforms to an XML Schema. However we may also mean it as a general purpose component that makes sure data conforms to specific rules. ie a Form validator would make sure that the input parameters to GUI/servlet/other conform to a set of rules (ie all fields supplied and validly formatted). -- Cheers, Pete "Invincibility is in oneself, vulnerability in the opponent." -- Sun Tzu -- To unsubscribe, e-mail: For additional commands, e-mail:
