Your cart has a reference to the sessionBean ShopingCart. This is not allowed, however. The IOC incjectionsupport makes this possible by wrapping this EJB reference with a serializable proxy.
I only have expecience with wicket-spring end it works great. (In your case, define your ejb reference in spring and inject it via wicket-spring support in your page. problem solved!
