Test.java

package com.sample.app;

import java.util.Calendar;
import java.util.Date;
import java.util.Set;

import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;

import com.sample.app.model.Employee;

public class Test {
	private static ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
	private static Validator validator = validatorFactory.getValidator();

	private static void validateBean(Employee emp) {
		System.out.println("************************************");
		Set<ConstraintViolation<Employee>> validationErrors = validator.validate(emp);

		if (validationErrors.size() == 0) {
			System.out.println("No validation errors....");
		}

		for (ConstraintViolation<Employee> violation : validationErrors) {
			System.out.println(violation.getPropertyPath() + "," + violation.getMessage());
		}
		System.out.println("");
	}

	public static void main(String args[]) {

		Employee emp1 = new Employee(1, "Krishna", Calendar.getInstance().getTime());
		System.out.println("Validation errors on bean emp1");
		validateBean(emp1);

		/* Setting tomorrow date to emp2 */
		Calendar c = Calendar.getInstance();
		c.setTime(new Date());
		c.add(Calendar.DATE, 1);

		Employee emp2 = new Employee(2, "Siva", c.getTime());
		System.out.println("Validation errors on bean emp2");
		validateBean(emp2);
	}
}

Output

Validation errors on bean emp1
************************************
joiningDate,must be a date in the present or in the future

Validation errors on bean emp2
