I have a stateful EJB that I am using to keep current user information within my application. This EJB is injected into the servlet controller and used to store the last user logged in. However, the session seems to be the same on every single client.

Sample EJB Code:

```
Stateful
@LocalBean
public class CurrentUserBean {

private string Username;

public void setUser(String un)
{
    Username = un;
}

....

```

Sample Servlet Code:

```
public class MainController extends HttpServlet {
       @EJB private CurrentUserBean userBean;

        protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

                HttpSession session = request.getSession();
                String name = session.getAttribute("username");

                userBean.setUser(name);
                ......

```

Now, when the application is deployed on my server and I have many different people talking to the server from several different clients, the username is always set to the last user that logged in. In other words, it seems as if the stateful session bean is keeping the same state across all clients. This confused me greatly, as I read in the java 6 ee tutorial the following quote from page 247:

>

Can someone explain why this is occurring and also explain how to use stateful beans in a proper manner that doesn't keep the same state across all clients?

Thank you.
