[jboss-user] [EJB 3.0] - Re: java.lang.ClassCastException: $Proxy79 getting conext

[rober-mpp]

Hi all, 

I'm having the ClassCastException issue, but I only have one remote interface.

This is my java code: 

        Hashtable<String, String> contextProperties = new Hashtable<String, String>();
  |         contextProperties.put( InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" );
  |         contextProperties.put( InitialContext.PROVIDER_URL, "jnp://127.0.0.1:1099" );
  |         
  |         InitialContext initialContext = new InitialContext( contextProperties );
  |         
  |         Object obj = initialContext.lookup( "ZaraServer/FachadaBean/remote" );
  |         
  |         FachadaInterfaz fachada = (FachadaInterfaz)obj;

The exception being throwed on the last line when trying to cast:

I think I may be going crazy with this issue, but I can't make it work.

Thanks all for your help
Cheers.
