Why tag not showing the Error Messages inside tag of Spring?

Question

tag not showing Error Messages when I put it inside the tag of Spring.

It shows Error Messages, If the tag is out of the tag. I have printed the errors of the binding result and it shows the errors as below:

[Field error in object 'student1' on field 'lastname': rejected value []; codes [Size.student1.lastname,Size.lastname,Size.java.lang.String,Size]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [student1.lastname,lastname]; arguments []; default message [lastname],16,6]; default message [Size.student1.**lastname**]]

Note: If I place inside the tag it is not working.

Here is the JSP code:

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>


    Contact Manager

        First Name
         
    
    
        Last Names
        
          
        
    

    
        DOB
        
    
    
        Email
        
    
    
        Telephone
        
    
    
        Skillset
        
            
        
    
    
        Flat Number : 
        
    
    
        Building Name : 
        
    
    
        City :

The Controller Method:

@RequestMapping(value="/addBean.html", method = RequestMethod.POST)
public ModelAndView addContactFromBean(@ModelAttribute("student1") @Valid ContactBean student1, BindingResult result){

    System.out.println("Inside addContactFromBean");

    if(result.hasErrors()){ // this binding result checks for error
        ModelAndView model = new ModelAndView("addStudent");
        System.out.println("Some error occured in input.");
        System.out.println(result.getAllErrors());
        return model;
    }

    ModelAndView model = new ModelAndView("viewStudent");

    System.out.println("Student Bean : "+student1.toString());
    model.addObject("student1", student1);

    System.out.println("View Name :->> "+model.getViewName());
    return model;
}

The Spring Bean:

package com.springTut;

import java.util.List;

import javax.validation.constraints.Size;

import org.hibernate.validator.constraints.NotEmpty;

public class ContactBean {
**@NotEmpty
private String firstname;**
**@Size( min=6, max=16, message="Size.student1.lastname")**
**private String lastname;**
private String email;
private String dob;
private Long telephone;
private List skillSet;
private AddressBean address;

@Override
public String toString() {
    return "ContactBean [firstname=" + firstname + ", lastname=" + lastname + ", email=" + email + ", telephone="
            + telephone + ", skillSet=" + skillSet + ", address=" + address + "--.]";
}
public String getDob() {
    return dob;
}
public void setDob(String dob) {
    this.dob = dob;
}
public List getSkillSet() {
    return skillSet;
}
public void setSkillSet(List skillSet) {
    this.skillSet = skillSet;
}
public String getFirstname() {
    return firstname;
}

public void setFirstname(String firstname) {
    this.firstname = firstname;
}
public String getLastname() {
    return lastname;
}
public void setLastname(String lastname) {
    this.lastname = lastname;
}
public String getEmail() {
    return email;
}
public void setEmail(String email) {
    this.email = email;
}
public Long getTelephone() {
    return telephone;
}
public void setTelephone(Long telephone) {
    this.telephone = telephone;
}
public AddressBean getAddress() {
    return address;
}
public void setAddress(AddressBean address) {
    this.address = address;
}
}

Binding and validation errors are registered in the model. The tag retrieves these errors from the model for display purposes. If the tag is nested inside a form:form tag the effective error key or path is the combination of the modelAttribute attribute in the form:form tag and the path you specify. In your case the modelAttribute is not explicit. Change your form as follows
