this is my function in the sessionEJB

public UserEntity authentification(String login, String pwd) {

        try{
            Query query;
            query = em.createQuery("select o from UserEntity o where " + " o.login = :LOGIN AND o.pwd = :PWD");
            query.setParameter("LOGIN",login);
            query.setParameter("PWD",pwd);
     return       
                 (UserEntity) query.getSingleResult();





        }

                e.printStackTrace();
                return null;
        }

    }

this is my backingbean

public String loginaction() {

        BindingContainer bindings = getBindings();
        OperationBinding operationBinding = bindings.getOperationBinding("authentification");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return "success";
        }
        return null;
    }

this is my faces-config

<?xml version="1.0" encoding="windows-1256"?>
<faces-config version="2.1" xmlns="http://java.sun.com/xml/ns/javaee">
  <application>
    <default-render-kit-id>oracle.adf.rich</default-render-kit-id>
  </application>
  <navigation-rule>
    <from-view-id>/login.jsf</from-view-id>
    <navigation-case>
      <from-action>#{backing_login.loginaction}</from-action>
      <from-outcome>success</from-outcome>
      <to-view-id>/untitled2.jsf</to-view-id>
      <redirect/> 
    </navigation-case>
  </navigation-rule>
</faces-config>

try returning a String instead of a null and use it in some navigation rule — Hichamov, Mar 18 '14 at 11:52
Yes exactly, in your backing bean instead of returning the null try returning "fail" for example and used with some navigation ruel to see whats the problem — Hichamov, Mar 18 '14 at 12:04
it's done but it shows an error ' Nom id introuvable dans l'objet donné : success.' that mean in english name Id not found in the given object — user3419507, Mar 18 '14 at 12:28
So you are getting the success outcome but its not in your navigation rules anymore, this is a good sign because it means that the success outcome is working. Be sure to have navigation rules for both outcomes -the faile and the success- — Hichamov, Mar 18 '14 at 14:35

In your backing bean method loginaction, instead of returning null (which means that you are telling the JSF to stay at the current view) you should return a string object, where the name of the page on which you want the function to redirect should be included. This format should work if you are working on a faces application (otherwise it should be similar, just check online):

return "/faces/nameOfPageToRedirect.jsf?faces-redirect=true";
