The Rules class is where you declare your validation. eg.

	new Rules(Owner.class) {
            protected void initRules() {
                add("firstName", getNameValueConstraint());
                add("lastName", getNameValueConstraint());
                add(not(eqProperty("firstName", "lastName")));
                add("address", required());
            }

            private Constraint getNameValueConstraint() {
                return all(new Constraint[] { required(), maxLength(25),
regexp("[a-zA-Z]*", "alphabetic") });
            }

        };

This code is out the pet clinic sample app for SpringRich.
