public class NameService

extends java.lang.Object

NameService utility class It locates and connects to the NameService and enables registration to the Name Service By default it uses NamingContextExt but can be recompiled to use the older NamingContext interface because it provides the extra utility classes internally. Additionally, it allows for connection to an insecure NameService from an SSL application using the locally developed ServiceInterface.
