So, I'm a grand spankin' greenhorn newbie...and I'm attempting to create a Stateful session bean using JBoss 4.0.4RC1 (on Windows).

I've got a small storefront application that has several Entity beans and SLSBs that have so far worked great...I'm not having any problems w/ my entities or stateless beans...very impressed so far.

However, I just created a ShoppingCart SFSB that throws an exception telling me it can't be found...even though it appears to be discovered by the server when deployed...so I'm obviously doing *somthing* wrong.

Most of my work has been by reference to the TrailBlazer sample app, which has been a great learning tool so far.

Here's the exception I'm getting:

10:19:05,275 ERROR [STDERR] javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean: 4snf2b-wb57nw-elb23ltf-1-elb2fol7-9

10:19:08,620 ERROR [STDERR] at com.myapp.proxy.CartProxy.addOrderLines(CartProxy.java:51)

Here's the method in CartProxy.java that's throwing the exception:

 public static void addOrderLines(Map<Configuration, Integer> orderLines)
 {
 ShoppingCart cart = null;

 try
 {
 //get EJB
 InitialContext ctx = new InitialContext();
 cart = (ShoppingCart)ctx.lookup(localEJB);

 //get collection from map
 int size = orderLines.size();
 Iterator i = orderLines.entrySet().iterator();

 //iterate over map
 for (int x=0; x<=size; x++)
 {
 //get key/value pair
 Entry entry = (Entry)i.next();
 Configuration cfg = (Configuration)entry.getKey();
 Integer qty = (Integer)entry.getValue();

 //build OrderLine
 OrderLine ol = new OrderLine();
 ol.setConfiguration(cfg);
 ol.setQuantity(qty);

 //add to cart SFSB
 cart.addOrderLine(ol);

 //TEMPORARY!!
 cart.checkout(); //cancel session
 }
 }
 catch (NamingException exp)
 {
 // TODO Auto-generated catch block
 exp.printStackTrace();
 }
 catch (Exception exp)
 {
 // TODO Auto-generated catch block
 exp.printStackTrace();
 }
 }
}

...it takes a Map, collected in the UI, creates an OrderLine entity bean, and adds each entity to the ShoppingCart.

Here's the SFSB (and interfaces):

public interface ShoppingCart
{
 void addOrderLine(OrderLine item);
 @Remove void checkout();
}

@Stateful
public class ShoppingCartBean
 implements ShoppingCartLocal, ShoppingCartRemote, Serializable
{
 private List<OrderLine> orderLines;
 @EJB private ProductsLocal products;

 public ShoppingCartBean()
 {
 orderLines = new ArrayList<OrderLine>();
 }

 public void addOrderLine(OrderLine item)
 {
 this.orderLines.add(item);
 }

 @Remove
 public void checkout()
 {
 System.out.println("To be implemented");
 }
}

@Local
public interface ShoppingCartLocal extends ShoppingCart
{
}

@Remote
public interface ShoppingCartRemote extends ShoppingCart
{
}

Now...it's saying it can't be found...which is odd because I see this when I deploy the app:

10:18:39,885 INFO [Ejb3AnnotationHandler] found EJB3: ejbName=ShoppingCartBean, class=com.myapp.session.ShoppingCartBean, type=STATEFUL

And, you'll notice the @Remove method in my SFSB, it is actually writing the output in the method *before* the exception is thrown!! I can see this when running the app and calling the @Remove method:

10:19:05,275 INFO [STDOUT] To be implemented

Any ideas? Thanks very much!
