[jboss-user] [JNDI/Naming/Network] - Proxy ClassCastException after successful EJB lookup

[cupdike]

Using the EJB3 trailerblazer as a guide (http://trailblazer.demo.jboss.com/EJB3Trail/serviceobjects/slsb/index.html) 
I've been trying to reference a SLSB via a local interface in the web tier.

The jndi environment looks like this for my APLEntityFacade EJB3 SLSB:

  |   |   +- APLEntityFacadeBean (class: org.jnp.interfaces.NamingContext)
  |   |   |   +- local (proxy: $Proxy1344 implements interface edu.jhuapl.ermp.service.ejb.APLEntityFacade,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
  |   |   |   +- remote (proxy: $Proxy1343 implements interface edu.jhuapl.ermp.service.ejb.APLEntityFacade,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)
  | 

I'm successfully doing a lookup on "ermpJpaHib/APLEntityFacadeBean/local".  However, the cast below fails with the ClassCastException (exception given at end of post):

aplEntityFacade = (APLEntityFacade)facade;

APLEntityFacadeBean is defined like this:


  | @Stateless
  | @Local
  | @TransactionAttribute(TransactionAttributeType.REQUIRED)
  | public class APLEntityFacadeBean 
  |     extends GenericEJB3DAO<APLEntity, Long> 
  |     implements APLEntityFacade {
  | 
    
Anyone have any idea what I'm doing wrong?  

TIA, Clark
