[jboss-user] [EJB 3.0 Users] - Re: JBoss 4.2.1 RemoteEJB Lookup ClassCastException

[kyle.bober]

So I modified my code as you stated by injecting the RemoteEJB interface using @EJB like so:


  | @EJB(mappedName=ICustomizationRemote.EJB_JNDI)
  | ICustomizationRemote theCustomizationService;
  | 

I now see the following exception. 


  | com.thesearchagency.mms.service.user.UserException: Non matching type for inject of field: com.thesearchagency.mms.service.customization.ICustomizationRemote com.thesearchagency.mms.service.user.impl.UserEJB.theCustomizationService for type: $Proxy164 of jndiName env/com.thesearchagency.mms.service.user.impl.UserEJB/theCustomizationService

Which is a much better sign then the ClassCastException :) What exactly does the mappedName parameter refer too? 

I have the following in my EJB Implementation class:


  | @Stateless
  | @LocalBinding(jndiBinding=ICustomizationLocal.EJB_JNDI)
  | @RemoteBinding(jndiBinding=ICustomizationRemote.EJB_JNDI)
  | @Interceptors(SpringBeanAutowiringInterceptor.class)
  | @XmlTransient
  | public class CustomizationEJB implements ICustomizationLocal, ICustomizationRemote {
