Provides contexts that implement the behavior of NetWare NCP extensions, such as discovering and accessing NCP Extensions. The NCPExtension interface allows you to send requests to and receive replies from NCP Extensions registered on a NetWare server. You cannot create new NCP extensions using JNDI; you can only access existing NCP extensions. You will usually use an NCP Extension if you have written it yourself in C or if a third party has provided it.

You cannot enter the NCP Extensions naming system directly. Since an NCP extension is bound to a server, you can access it only from the Server naming system.
