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-name>ShoppingCartBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local>com.myapp.session.ShoppingCartLocal</local>
<ejb-link>MyProjectEJB.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,
