而深化發展，我得到這個錯誤我的應用程序JSF：未找到方法
javax.el.MethodNotFoundException: /test.xhtml @18,99

實體Complexe.java
import java.util.HashSet;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;
/**
* Complexe generated by hbm2java
*/
@Entity
@Table(name="COMPLEXE"
,schema="PROJET"
)
public class Complexe implements java.io.Serializable {
private String nomComp;
private ZoneParc zoneParc;
private Set<Parc> parcs = new HashSet<Parc>(0);
public Complexe() {
}
public Complexe(String nomComp) {
this.nomComp = nomComp;
}
public Complexe(String nomComp, ZoneParc zoneParc, Set<Parc> parcs) {
this.nomComp = nomComp;
this.zoneParc = zoneParc;
this.parcs = parcs;
}
@Id
@Column(name="NOM_COMP", unique=true, nullable=false, length=30)
public String getNomComp() {
return this.nomComp;
}
public void setNomComp(String nomComp) {
this.nomComp = nomComp;
}
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="NOM_ZONEE")
public ZoneParc getZoneParc() {
return this.zoneParc;
}
public void setZoneParc(ZoneParc zoneParc) {
this.zoneParc = zoneParc;
}
@OneToMany(cascade=CascadeType.ALL, fetch=FetchType.LAZY, mappedBy="complexe")
public Set<Parc> getParcs() {
return this.parcs;
}
@Override
public int hashCode() {
int hash = 0;
hash += (nomComp != null ? nomComp.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Complexe)) {
return false;
}
Complexe other = (Complexe) object;
if ((this.nomComp == null && other.nomComp != null) || (this.nomComp != null && !this.nomComp.equals(other.nomComp))) {
return false;
}
return true;
}
public void setParcs(Set<Parc> parcs) {
this.parcs = parcs;
}
}
現在ComplexeDaoImpl.java
import config.HibernateUtil;
import fr.code.parc.model.Complexe;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
/**
*
* @author raddaouirami
*/
public class ComplexeDaoImpl implements ComplexeDao{
@Override
public List<Complexe> list() {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction t = session.beginTransaction();
List complexes = session.createQuery("from Complexe").list();
t.commit();
return complexes;
}
@Override
public Complexe getComplexe(String nomComp) {
Session session = HibernateUtil.getSessionFactory().openSession();
return (Complexe) session.load(Complexe.class, nomComp);
}
@Override
public void save(Complexe complexe) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction t = session.beginTransaction();
session.save(complexe);
t.commit();
}
@Override
public void update(Complexe complexe) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction t = session.beginTransaction();
session.update(complexe);
t.commit();
}
@Override
public void remove(Complexe complexe) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction t = session.beginTransaction();
session.delete(complexe);
t.commit();
}
}
和最後ComplexeController.java
import fr.code.parc.dao.ComplexeDao;
import fr.code.parc.dao.ComplexeDaoImpl;
import fr.code.parc.model.Complexe;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
/**

*/
@ManagedBean
@SessionScoped
public class ComplexeController {
private Complexe complexe;
private DataModel listeComplexes;
private int selectedItemIndex;
/**
* Creates a new instance of ComplexeController
*/
public ComplexeController() {
complexe = new Complexe();
}
/* public Complexe getSelected() {
if (complexe == null) {
complexe = new Complexe();
selectedItemIndex = -1;
}
return complexe;
}*/
public DataModel getListeComplexes() {
List<Complexe> liste = new ComplexeDaoImpl().list();
listeComplexes = new ListDataModel(liste);
return listeComplexes;
}
/**
* @return the complexe
*/
public Complexe getComplexe() {
return complexe;
}
/**
* @param complexe the complexe to set
*/
public void setComplexe(Complexe complexe) {
this.complexe = complexe;
}
public String preparationAddComplexe(){
setComplexe(new Complexe());
return "test";
}
public String preparationEditComplexe(){
setComplexe((Complexe)(getListeComplexes().getRowData()));
return "test";
}
public String DeleteComplexe(){
Complexe complexes = (Complexe)(getListeComplexes().getRowData());
ComplexeDao dao = new ComplexeDaoImpl();
dao.remove(complexes);
return "complexe";
}
public String SaveComplexe(){

}
public String UpdateComplexe(){
