JSF: method not found - jsf

Question

I'm getting this error while developping my application
javax.el.MethodNotFoundException: /test.xhtml #18,99
action="#{ComplexeController.saveComplexe}": Method not found:
fr.code.parc.controller.ComplexeController#97aead.saveComplexe()

the entity 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;
/**

#Entity

)
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.parcs = parcs;
}
#Id
#Column(name="NOM_COMP", unique=true, nullable=false, length=30)

return true;
}
public void setParcs(Set<Parc> parcs) {

}
and now ComplexeDaoImpl.java
import config.HibernateUtil;
import fr.code.parc.model.Complexe;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
/**

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();

t.commit();
}
#Override
public void remove(Complexe complexe) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction t = session.beginTransaction();
session.delete(complexe);
t.commit();
}
}
and Finally ComplexeController.java

}
/* public Complexe getSelected() {

}
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;
}
/**

*/
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(){
ComplexeDao dao = new ComplexeDaoImpl();
dao.save(getComplexe());
return "complexe";
}
public String UpdateComplexe(){
ComplexeDao dao = new ComplexeDaoImpl();
dao.update(complexe);
return "complexe";
}
}
How can I solve it?

Answer 1

In view you invoke saveComplexe
action="#{ComplexeController.saveComplexe}"
ComplexeController has only SaveComplexe method.
Either change to
action="#{ComplexeController.SaveComplexe}"
or rename method in ComplexeController to saveComplexe

Answer 2

2 Solutions:
Solution 1.
Change in test.xhtml : complexeController.saveComplexe [Notice first letter in complexeController is in smaller case]
<h:commandButton action="#{complexeController.saveComplexe}" value="Insérer un nouveau complexe"/>
<h:commandButton action="#{complexeController.updateComplexe}" value="Modifier un complexe"/>
Solution 2.
Change in ComplexeController.java:
#ManagedBean(name="ComplexeController ")
#SessionScoped
public class ComplexeController {
....
}
Read the Following Info about Configuring ManagedBeans in JSF:
There are 2 ways to use #ManagedBean to expose a Java Bean class to Managed Bean class.
Way 1.
#ManagedBean
public class ComplexeController{
....
}
In this case the bean exposed with same name but the first letter is smaller case, i.e., you can access the bean in Facelet as
#{complexeController}
Way 2.
#ManagedBean(name="myBean")
public class ComplexeController{
....
}
In this case the bean exposed with same name but the first letter is smaller case, i.e., you can access the bean in Facelet as
#{myBean}

Answer 3

Try to access the ManagedBean with first char to low case
e.g.
action="#{complexeController.saveComplexe}"
instead of
action="#{ComplexeController.saveComplexe}"
