Class.cast.Exception when Accessing a Session bean on 4.0.5
Can anyone help me - I'm at a loss. I'm also embarrassed because I think this should be easy. I've deployed my application in an EAR, it contains a JSF web app, and some EJB's.
Here's the code I use to call the bean.
InitialContext context = new InitialContext();
Object objref = context.lookup("ReservationManager");
ReservationManagerHome reservationManagerHome =
(ReservationManagerHome)PortableRemoteObject.narrow(objref, ReservationManagerHome.class);
_reservationManager =
(ReservationManager)reservationManagerHome.create();
The context.lookup successfully returns a proxy, but the narrow function throws a Class Cast Error shown below:
2006-12-07 14:56:13,610 ERROR [businesstier.base.ReservationsClassFactory] java.lang.ClassCastException
The deployment reports no errors -> here's the log:
DEBUG [org.jboss.ejb.EJBDeployer.verifier] Bean checked: ReservationManager: Verified. ... INFO [org.jboss.ejb.EjbModule] Deploying ReservationManager ... DEBUG [org.jboss.ejb.EjbModule] creating binding for ReservationManager:stateless-rmi-invoker ...

INFO [org.jboss.ejb.plugins.local.BaseLocalProxyFactory] Bound EJB LocalHome 'ReservationManager' to jndi 'local/ReservationManager@15468898'
I can see it as a service in the JMX-Console
The Web.XML looks like this:
<ejb-ref> <ejb-ref-name>ejb/ReservationManager</ejb-ref-name> <ejb-ref-type>Session</ejb-ref-type> <home>businesstier.impl.ReservationManagerHome</home> <remote>businesstier.impl.ReservationManager</remote> <ejb-link>ReservationManager</ejb-link> </ejb-ref>
The ejb-jar.xml looks like this:
<session> <description>Session Bean ( Stateless )</description> <display-name>ReservationManager</display-name> <ejb-name>ReservationManager</ejb-name> <home>businesstier.impl.ReservationManagerHome</home> <remote>businesstier.impl.ReservationManager</remote> <local-home>businesstier.impl.ReservationManagerLocalHome</local-home> <local>businesstier.impl.ReservationManagerLocal</local> <ejb-class>businesstier.impl.ReservationManagerBean</ejb-class> <session-type>Stateless</session-type> <transaction-type>Container</transaction-type> ...
The deployment works like a charm on Oracle Application Server 10g.
I'm completely stumped. What am I missing.
Thanks,
Nigel
