Hibernate validator doesn't work

I'm using Hibernate validator with Hibernate and Spring, but it seems that validations don't work. When I don't enter a String or enter a String of 1 character (which is not between min=4 and max=20) is not showing any error and therefore saves in the table. What am I missing?

package dao;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

@Entity
@Table(name="etudiant")
public class Etudiant {

    @Id
    @Column(name="ID_ETUDIANT")
    @GeneratedValue
    private Long idEtudiant;

    @Column(name="NOM")
    @Size (min=4, max=20)
    private String nom;

    @Size(min=4, max=20, message="nom doit etre entre 4 et 20 svp..")
    @Column(name="PRENOM")
    private String prenom;

    @Column(name="DATE_NAISSANCE")
    @Temporal(TemporalType.DATE)
    private Date dateNaissance;

    @NotNull
    @Column(name="EMAIL")
    private String email;

    public Etudiant() {
        super();
    }

    public Long getIdEtudiant() {
        return idEtudiant;
    }

    public void setIdEtudiant(Long idEtudiant) {
        this.idEtudiant = idEtudiant;
    }

    public Etudiant(String nom, String prenom, Date dateNaissance, String email) {
        super();
        this.nom = nom;
        this.prenom = prenom;
        this.dateNaissance = dateNaissance;
        this.email = email;
    }

    public String getNom() {
        return nom;
    }

    public void setNom(String nom) {
        this.nom = nom;
    }

    public String getPrenom() {
        return prenom;
    }

    public void setPrenom(String prenom) {
        this.prenom = prenom;
    }

    public Date getDateNaissance() {
        return dateNaissance;
    }

    public void setDateNaissance(Date dateNaissance) {
        this.dateNaissance = dateNaissance;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

Controller:

@RequestMapping(value="save",method=RequestMethod.POST)
public String  saveetudient(Model md,
        @Valid @ModelAttribute("etudiant") Etudiant et, 
        BindingResult res) {
    if (res.hasErrors()) {
        List <Etudiant> ets=service.listeEtudiants();
        md.addAttribute("etudiants",ets);
        return "etudiant1";
    }
    else {
        service.addEtudiant(et);
        List <Etudiant> ets=service.listeEtudiants();
        md.addAttribute("etudiants",ets);
        return "etudiant1";
    }
}

In JSP I put this line to show errors:

<form action="save" method="post">

  <table border="1" width="500" bgcolor="grey">

 <tr> 

 <th>Nom </th>
<th>Prenom </th>
<th> Date de naissance</th>
<th>Email </th>
</tr>


<tr> 
 <td>  <input type="text" name="nom" >   </td>
 <td> <input type="text" name="prenom" >  </td>
 <td>  <input type="text" name="dateNaissance" > </td>
  <td> <input type="text" name="email" >  </td>
 </tr>

 </table>  <br>
 <input type="submit" value="ajouter">

 <sform:errors path="etudiant.*"/>
 <sform:errors path="prenom"/> 
</form>
