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