ragavgomatam, I've tried with the code: | HttpSession session = | (HttpSession) FacesContext.getCurrentInstance(). | getExternalContext().getSession(false); | session.invalidate(); | but unfortunately it doesn't work because at this point in the web life cycle when the web container calls the method marked with the @PreDestroy annotation to do the cleanup, FacesContext.getCurrentInstance() returns null. So, I get the following exception: | 2008-08-12 08:26:37,343 ERROR [org.jboss.web.jsf.integration.injection.JBossInjectionProvider] PreDestroy failed on managed bean. |

br.urca.www.biblioteca.dados.ejb.AutenticacaoEJB.logout(AutenticacaoEJB.java:34) | at br.urca.www.biblioteca.web.PesquisaAcervo.finalizar(PesquisaAcervo.java:60) | I placed System.out.println calls and I saw that really FacesContext.getCurrentInstance() is returning null at this point. In my application there's not a logout button or whatever for the user to logout. All this is happening when I'm redeploying the application to the server, and the server is in the process of shutting down the old application that was running. This application that I'm developing doesn't have to have any security restrictions. I mean, everyone could access it and I don't need to secure my EJBs restricting access to some roles. So, I was wondering as I'm able to make EJB calls without authentication (as was shown previously), wouldn't be ok to just proceed like this? I think that when I don't provide an authenticated user to JBoss, it is using something like this behind the scenes automatically for me (correct me if I'm wrong), if not I wouldn't be able to make method calls. So, if JBoss releases the resources it allocates when the session expires, it would be ok for me. So, what do you have to tell me about this? How JBoss behave in this case? Is this a good approach for me to follow? If not, what would be another place for me to do the logout from the WebAutentication facility? Thank you.
