Re: Wicket 1.4 + GF v2.1 causing WicketNotSerializableException
I'm not injecting it directly. I'm using a proxy class to get a reference
to the stateless bean's interface like so:
public class CartProxy
{
private static ShoppingCartLocal lookupCartInterface()
{
ShoppingCartLocal cart = null;
try
{
InitialContext ctx = new InitialContext();
cart =
(ShoppingCartLocal)ctx.lookup(java:comp/env/ShoppingCartBean);
}
catch (NamingException exp)
{
LogProxy.saveEntry(exp);
}
return cart;
}
}
The reference in web.xml makes this possible:
ejb-local-ref
ejb-ref-nameShoppingCartBean/ejb-ref-name
ejb-ref-typeSession/ejb-ref-type
localcom.myapp.session.ShoppingCartLocal/local
ejb-linkMyProjectEJB.jar#ShoppingCartBean/ejb-link
/ejb-local-ref
Is this not supposed to work? It's been in production for over 3 yrs...so I
hope it does! :)
The entire app is built this way and this one page is the only one throwing
this exception. It works, it doesn't stop the show or affect anything
negatively, so far as I can tell. I would just like to get rid of it and
figure out what it is.
Thanks again,

Re: Wicket 1.4 + GF v2.1 causing WicketNotSerializableException
I reference the bean's interface in order to use it, yes. What's the
alternative? Would I instead access everything through a proxy class and
store the proxy itself into the WebSession, to retain a reference? As it
is, each page in the checkout process changes the Stateful bean's properties
and stores it back into the WebSession. Here is what the Cart page looks
like, in summary:
public class Cart extends BasePage
{
public Cart()

i am going to guess that inside //stuff happens here... you access

keeps a reference, so that is what is causing your serialization
problem. instead of having the final field, do the lookup
((UserSession)getSession()).getCart(); directly inside the //stuff

try

//proxy method to remove line item

I've got an e-commerce application that is simply moving between two pages using setRedirectPage() when going from a product detail page to the shopping cart page. There isn't anything remarkable about either of these two pages, they're basically like any other in the app. However, when the cart page loads, I get the exception at the bottom of this message. I've tried implementing Serializable on the Cart() page class but it makes no difference. It points out com.sun.ejb.containers.EJBLocalObjectInvocationHandlerDelegate as the culprit. I use a stateful session bean (ShoppingCart) which is passed around the app as part of the session (custom WebSession-derived class) This is the only page this occurs on. There are several other steps in the cart's checkout process that look exactly like this one and the exception doesn't happen on any of the others Any ideas?
