SAME EJB 3.0 Stateful Session bean for different JSP sessions returned

Question

Forum,
I have a strange problem utilizing stateful session beans. Please note, that I am using jdeveloper for the following:
1) Here is a basic stateful session bean:
@Stateful(name = "DemoClass")
public class DemoClassBean implements DemoClass,
           DemoClassLocal, SessionSynchronization {
      public static int id=0;
      public DemoClassBean() {
      id++;
      public int getId() {
         return id;
      //... other methods
}2) This bean is accessed from a JSP for testing purpose, I am copying only the script used in JSP:
<%
   DemoClass bean = null;
   try {
      bean = (DemoClass) ((new javax.naming.InitialContext()).
                   lookup("DemoClass "));
      System.out.println("ID=" + bean.getId() );
      } catch (javax.naming.NamingException e) {
         // TODO
%>If this page is addressed by different clients, from different browsers, the same bean is returned.
Here is what I see in the logs:
ID=1
ID=1
ID=1
The same problem is being observed when this session bean is accessed from a JSF Backing bean.
What could be wrong? Is this a bug in oc4j / jdeveloper (version 10.1.3.3.0)?

Hi,
The code for stateful is perfectly fine and working in a normal way. The way you are trying to implement the stateful session bean in your application is wrong.
think of binding the stateful session bean with HttpSession object.
So that you will get a unique stateful session bean object.
