insert java.sql.Timestamp data in oracle timestamp(6) column using Hibernate -

i want insert line in table called vol in oracle database using struts2 form insert action returns "input" , don't execute insertion vol.java code:

package models;  import java.sql.timestamp; import java.util.date;  import javax.persistence.entity; import javax.persistence.id; import javax.persistence.table; import javax.persistence.temporal; import javax.persistence.temporaltype;  @entity @table(name="vol") public class vol { @id private int idvol; private string typeavion; private string nomavion; private string depart; private string destination; @temporal(temporaltype.timestamp) private date heuredepart; private string heurearrivee; private string technicien;  public int getidvol() { return idvol; }  public void setidvol(int idvol) { this.idvol = idvol; }  public string gettypeavion() { return typeavion; }  public void settypeavion(string typeavion) { this.typeavion = typeavion; }  public string getnomavion() { return nomavion; }  public void setnomavion(string nomavion) { this.nomavion = nomavion; }  public string getdepart() { return depart; }  public void setdepart(string depart) { this.depart = depart; }  public string getdestination() { return destination; }  public void setdestination(string destination) { this.destination = destination; }  public date getheuredepart() { return heuredepart; }  public void setheuredepart(date heuredepart) { this.heuredepart = heuredepart; }  public string getheurearrivee() { return heurearrivee; }  public void setheurearrivee(string heurearrivee) { this.heurearrivee = heurearrivee; }  public string gettechnicien() { return technicien; }  public void settechnicien(string technicien) { this.technicien = technicien; }    public vol(){  }  } 

this code of form:

<s:form action="ajoutvol" method="post"> <s:textfield name="vol.idvol" label="idvol" size="20" /> <s:textfield name="vol.typeavion" label="type avion" size="20" /> <s:textfield name="vol.nomavion" label="nom avion" size="20" /> <s:textfield name="vol.depart" label="depart" size="20" /> <s:textfield name="vol.destination" label="destination" size="20" /> <s:textfield name="heuredepart" label="heure de dapart" size="20" /> <s:textfield name="vol.heurearrivee" label="heure d'arrivée" size="20" /> <s:textfield name="vol.technicien" label="technicien" size="20" /> <s:submit name="submit" label="submit"  /> </s:form> 

this execute method of action:

public string execute(){     voldao vd= new voldao();     simpledateformat dateformat = new simpledateformat("yyyy-mm-dd hh:mm:ss");     try {         vol.setheuredepart(dateformat.parse(heuredepart));     } catch (parseexception e) {         // todo auto-generated catch block         e.printstacktrace();     }     vd.insertvol(vol);     map session = actioncontext.getcontext().getsession();     session.put("vol", vol);     return success; } 

and code of method insertvol():

public void insertvol(vol vol){     sessionfactory sessionfactory=new annotationconfiguration().configure().buildsessionfactory();     session session=sessionfactory.opensession();     session.begintransaction();     session.save(vol);     session.gettransaction().commit();     session.close();     sessionfactory.close(); } 

use following code insert timestamp data timestamp oracle type

vol.setheuredepart(new timestamp(dateformat.parse(heuredepart).gettime())); 

the entity should map column like

@column(name = "heure_depart", length = 19) private date heuredepart;
