Error integration jsf +spring +hibernate +managedbean - spring

Question

I have web application wich uses jsf 2.0 and spring 3.0 +hibernate 4 The problem is that: jsf managed beans can't use spring beans using dependency injection There are my config files:
Rq When I change Mybean like that #ManagedBean(name="userMB")
#RequestScoped
and I put #ManagedProperty(value="#{Service}") it is recognized on jsf page but there is error
package com.ardia.service;
import java.util.List;
import com.ardia.model.Composant;
public interface ComposantService {
void inserComposant(Composant comp);
Composant getComposantById(int compId);
Composant getComposant(String compname);
List<Composant> getComposants();
}
this is my service
package com.ardia.service;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.ardia.model.Composant;
#Service("compService")
#Transactional
public class ComposantImp implements ComposantService {
#Autowired
SessionFactory sessionFactory;
#Override
public void inserComposant(Composant comp) {
// TODO Auto-generated method stub
sessionFactory.getCurrentSession().saveOrUpdate(comp);
}
#Override
public Composant getComposantById(int compId) {
// TODO Auto-generated method stub
return (Composant) sessionFactory.
getCurrentSession().
get(Composant.class, compId);
}
#Override
public Composant getComposant(String compname) {
// TODO Auto-generated method stub
return null;
}
#Override
#SuppressWarnings("unchecked")
public List<Composant> getComposants() {
// TODO Auto-generated method stub
Criteria criteria = sessionFactory.
getCurrentSession().
createCriteria(Composant.class);
return criteria.list();
}
}
This is My Managed Bean
package ardia.beans;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import com.ardia.model.Composant;
import com.ardia.service.ComposantService;
#Component("compBean")
#Scope("session")
public class CoposantBean implements Serializable{
#Autowired
private ComposantService service;
private List<Composant> list;
#PostConstruct
public void init()
{
list=service.getComposants();
}
public List<Composant> getList() {
return list;
}
public void setList(List<Composant> list) {
this.list = list;
}
}
this is My application context spring

Answer 1

The classes which hold spring stereo typed beans (here your backing beans are holding them) should be instanciated via Spring Factories, but backing beans are created by JSF framework. Just use Spring EL Resolvers for JSF to overcome this. He is a relevant discussion and documentation
Also, make sure you have the spring bootstrap configured in the web application context loading via web.xml
<!-- Spring Bootstrap -->
