Lifecycle of @Applicationscoped at Ear

Question

I have an application with several WEB modules and an EJB inside an EAR as shown below:

In the EJB module I created a class annotated with @ApplicationScoped, my goal is for this class to store information that must be passed between WEB projects.
It happens that when adding information in the class in the project Portaltrainingsweb they are not visible in the project Moduloaluno for example.

Follows code of the class that is annotated with @ApplicationScope

@ApplicationScoped
public class ServiceAutenticacao {

private Map<String, Colaborador> mapaTickets = new HashMap<String, Colaborador>();


public ServiceAutenticacao(){
    System.out.println("Objeto service Autenticação criado...........................");
}

public void adicionaColaborador(String ticket, Colaborador colaborador){
    this.mapaTickets.put(ticket, colaborador);
}


public Colaborador getColaborador(String ticket) throws ServiceException{
    if(mapaTickets.containsKey(ticket)){
        return mapaTickets.get(ticket);
    }else{
        throw new ServiceException("Ticket de autenticação inválido: " + ticket);
    }
}
}

It follows how I write information on the object of this class in the project Portaltrainingsweb:

@ManagedBean
@SessionScoped
public class PrincipalController {

@Inject private ServiceAutenticacao serviceAutenticacao;

public void redirecionaModuloAluno(){
    //pendura o colaborador com um ticket no Servico de Autenticação entre projetos
    String ticketInterno = UtilService.generateOid();
    this.serviceAutenticacao.adicionaColaborador(ticketInterno , this.colaboradorAutenticado);

    HttpServletRequest req = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
    String url = req.getRequestURL().toString();
    String urlModuloAluno = url.substring(0, url.length() - req.getRequestURI().length()) + "/ModuloAluno/autenticacao/autenticacao.jsf?ticketinterno="+ticketInterno;

    FacesContext context = FacesContext.getCurrentInstance();

    try {
        context.getExternalContext().redirect(urlModuloAluno);
    } catch (IOException e) {
        e.printStackTrace();
    }

}

And how I try to get this information in the project Moduloaluno:

@ManagedBean
@RequestScoped
public class AutenticacaoController {

@Inject private ServiceAutenticacao serviceAutenticacao;

Colaborador colaborador  = serviceAutenticacao.getColaborador(this.ticketInterno);
            System.out.println("Colaborador: " + colaborador.getNome());
            principalController.setColaboradorAutenticado(colaborador);

I put a System.out in the class constructor ServiceAutenticacao and I realized that she’s being instantiated over and over again. So my question is, the object noted with @ApplicationScope is the same among several projects of the same EAR ? If so, would you tell me why I can’t access the information on the other project(ModuloAluno)

Answer 1

I found this bug/Issue in Jboss: https://issues.jboss.org/browse/CDI-129

What it says there is that the operation was not specified completely and the decision that @Applicationscoped is instantiated once only by EAR (rather than once by WAR) is relatively recent, so it may not be working as desired on current servers.

In a quick read, I saw that only in CDI 2.0 we will have this behavior (1 instance by EAR) guaranteed :(
