Cart example is not stateful!?
Hi all,
I need to implementing a stateful Session Bean. So, I took the Cart-example
and added the following thinks to look the values of a stateful bean who
shall be in the container (because by first call of this program, I added
some beans).
But, all Beans are destroyed. I can't see the STATEFUL beans of the
last program-call!
Why there not persistent?
Client:
// init Context
java.util.Properties p = new java.util.Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClientInitialContextFactory");
p.put(Context.PROVIDER_URL,"ormi://localhost/caddie");
p.put(Context.SECURITY_PRINCIPAL,"admin");
p.put(Context.SECURITY_CREDENTIALS,"metrocine");
Context context = new InitialContext(p);
// get Cart bean
Object homeObject = context.lookup("java:comp/env/Cart");
CartHome home = (CartHome)PortableRemoteObject.narrow(homeObject,
CartHome.class);
Cart cart = (Cart)PortableRemoteObject.narrow(home.create("kuno"),
Cart.class);
// print-out of all item stored in the stateful bean
java.util.Collection items = cart.getItems();
java.util.Iterator iterator = items.iterator();
while(iterator.hasNext()){
System.out.println((String)iterator.next());
}
// Add some new items to the Cart.
cart.add("Milk");
cart.add("Apples");
cart.add("Pizza");
