Pessoal, eu consegui resolver o problema da seguinda maneira, pelo que eu andei pesquisando mais parece que os conversores nao tem o ioc entao eh necessario que vc acesse a interface na mao msm como mostrado abaixo:

@SuppressWarnings("unchecked")
    private IUnidadeFederativaRemote unidadeFederativaRemote() throws NamingException{
       
        try {
             Hashtable props = new Hashtable(); 
             props.put( InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" ); 
             props.put( InitialContext.PROVIDER_URL, "localhost" );
             InitialContext initialContext = new InitialContext(props);
           
            return (IUnidadeFederativaRemote) initialContext.lookup("ProjetoEAR/ClasseQueImplementaAInterface/remote");
        } catch (NamingException e) {
            e.printStackTrace();
        }
        return null;
    }

logo apos eu tive um problema de Validation Error: Value is not valid

que resolvi seguindo esse post:

Grande abraço.
