This Validator class will validate a Car: 'WEB-INF/src/springmvc/validator/CarValidator.java'
package springmvc.validator;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
import springmvc.model.Car;
public class CarValidator implements Validator {
public boolean supports(Class aClass) {
return Car.class.equals(aClass);
}
public void validate(Object obj, Errors errors) {
Car car = (Car) obj;
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "model", "field.required", "Required field");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "price", "field.required", "Required field");
if ( ! errors.hasFieldErrors("price")) {
if (car.getPrice().intValue() == 0)
errors.rejectValue("price", "not_zero", "Can't be free!");
}
}
}

You can clearly see from the screen shots in earlier sections of the tutorial that Jérôme is using Eclipse. However I think he is doing a good job of hiding it as tutorials should be generic as possible. Not everybody uses NetBeans or Eclipse.

Spring bind tag is old when compared to the <form:tag> and the error messages are not displayed after validation when spring tag is used.

Hi, i've solve the problem:
you have to create a messages.properties file with:
typeMismatch=invalid field
typeMismatch.int=This value have to be integer
typeMismatch.java.lang.Integer={0} have to be Integer.
typeMismatch.java.util.Date={0} have to be Date, use format MM/dd/yyyy.
and then map this in your application-context.xml with:
messages
That's all

Is there a way to remove the added errors from the Errors object
kishore
December 28, 2009

Hi,
I'm adding all the field validation errors as follows
errors.rejectValue(fieldName, errorCode)
once i add the error based on some logic i want to remove the corresponding error from the 'errors'. How can i remove an added error from the errors object. I searched and not found any remove method on errors to remove the same. Can any one please help on this.
