NEW SESSION - Firefox, IE and GLASSFISH

Question

Hi all,
Here is my issue:
I have One application on Glassfish using EJB3,JPA and JSF.
Users can log to this application and have severals sessions opened simultanoulsy as each session is having a connection to its own database
How do I force a new session (particularly in Firefox as IE<=8 has no issue) and have the user using the same application but different databases in different tabs or windows of Firefox.
I tried almost all and get blocked
Many thanks in advance for your answers

Hi BalusC
Great Blog by the way...
Let me explain.
My architecture is as follows: using JSF, Glassfish and ...SQL Server!! (! i know but this is mandatory requirement as our application is full web version of an existing ERP application already sold and installed by more than 1000 of our customers...
I am using
JSF-->JSF Managed Bean (Session for some and Request for almost all when logged )-->EJB Interface-->EJB Impl-->Entity-->Database
I have a persistence Unit (using JTA and CMP) per database , each using a connection pool managed by Glassfish.
At the begining of my application, the user (when logging), choose a database, ...enter logging info and connect.
All databases have the schema but not the same data
You have to see in our case, a database as a company with particular configuration, customers, orders, invoices, contacts....
Our application is ERP that our customers uses to managed several companies simultanously .
Also, I need Session Scope as there is configuration data that I need to keep over all pages.
This configuration data is depending on the database connected to.
When selecting the database (company) for combo in logging form, The only way I found is fisrt to check is database(company) exists and can be connect to using at first begining Persistence.CreateEntityMangerFactory.. (i know that this is not J2EE and CMP but merly used in Java SE environments..).
This step is only used for checking database
Then, if creation did not generate a Persistence Exception , I can the use CMP and an EnityManger in EJB by JNDI lookup (as DI is not possible because you need constant in unitName)
ex :
@PersistenceContexts({
   @PersistenceContext(name="pu/SOCIETE1", unitName="SOCIETE1"),
   @PersistenceContext(name="pu/SOCIETE2", unitName="SOCIETE2"),
   @PersistenceContext(name="pu/SOCIETE3", unitName="SOCIETE3"),
   @PersistenceContext(name="pu/SOCIETE4", unitName="SOCIETE4"),
   @PersistenceContext(name="pu/SOCIETE5", unitName="SOCIETE5"),
   @PersistenceContext(name="pu/GENESYS_EXEMPLE", unitName="GENESYS_EXEMPLE")
@Stateless
public class SomeEJB extends CommonEjbImpl implements SomeEJBLocal  {
    private EntityManager em;
    @PostConstruct
    public void init() {
         String puName = (String) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("database"));
         em = (EntityManager) new InitialContext().lookup("java:comp/env/pu/"+puName);
    @PreDestroy
    public void cleanup() {
        if (em != null && em.isOpen()) {
            em.close();
}All works perfectly under IE6,IE7 and IE8 (forcing some parameter at launch of IE8).
But due to session management of Firefox (sharing session cookie among all exe or tabs)...session data is kept when opening a new tab.
What I did to avoid confilcts, is to clear FacesContext SessionMap when redirecting to Login page ...but i still can NOT log to multiple PU simultanously....
I do not see where DAO pattern could help me ...
Am I missing something here?
Many thanks in advance for your quick answer
