Hi,

I'm getting a strange ClassCastException when trying to lookup a Stateless Session Bean from within my myfaces managed bean. What I'm doing is simply call 


  | SicherheitsDatenBean sdb = (SicherheitsDatenBean) CTX.lookup("JSF-REACH/SicherheitsDatenBean/local");
  | 

to obtain a bean instance from FacesContext CTX.

The bean is registered in JNDI under that name, I can see it in my JBoss' jmx console (JBoss version 4.05 GA):
 
  | +- JSF-REACH (class: org.jnp.interfaces.NamingContext)
  |   |   +- SicherheitsDatenBean (class: org.jnp.interfaces.NamingContext)
  |   |   |   +- local (proxy: $Proxy104 implements interface business.SicherheitsDaten,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
  | 

This is the exception:
