Resolution

The Context.INITIAL_CONTEXT_FACTORY should be com.sun.jndi.cosnaming.CNCtxFactory when using a standalone java client trying to invoke EJBs via IIOP on JBoss EAP 7

See How to expose an EJB via IIOP and call it in JBoss EAP 7 / 6 which shows how to invoke IIOP from a standalone java client and from a client running in JBoss EAP
