  Hey Saravan,
  You exactly pointed out what i am looking for.

  I agree with your suggesion. That is the one of the solution. But the scenario is like this, everytime the user makes the request we check wheter the user is valid or not. For each request we check the session exist for this user or not. If we put this information in DB, then it will make a huge impact on performance since database operation is very costly. What do you think?

    As per my knowledge, the spec does not support that. 
    You are looking for something which is equivalent to ServletContext in WebContainer.
    I think if u create a UID in database with a key and value and store the 
    client's state information and use it as required. Hopefully this may serve ur purpose.

      Hey Saravana,

      Thanks for Reply. There is one catch, as per my knowledge the Stateful bean is for each client specific. It does not share information for multiple clients (EJB clients). I want a single place where i can put the information about session for all users and then i can check whether the user has proper session created or not.
      i want One bean for Multiple users for storing the shared information and that work in cluster.

          Hi All, 

          I have one scenarion. Will apreciate if you can give some valuable information. 
          We are currently working on J2EE application and we ar only dealing with Server side components. 
          I want to maintain the session information in EJBS, how can I do that i.e. I want to provide the same functionality as HttpSession provides in Servlet.

          I would also like to know how it is going to work in cluster enviorment. 

          Thanks in advance. 

          Regards, 
          Saidas Kottawar
