The Java Naming and Directory InterfaceTM (JNDI)
provides naming and directory functionality to applications written
in the JavaTM programming language. It
is designed to be independent of any specific
naming or directory service implementation. Thus a variety of services--new,
emerging, and already deployed ones--can be accessed in a
The JNDI architecture consists of an API (Application Programming Interface) and an
SPI (Service Provider Interface). Java applications use this API to access a
variety of naming and directory services. The SPI enables a variety of naming and
directory services to be plugged in transparently, allowing the Java application
using the API of the JNDI technology to access their services.
JavaTM 2 SDK, v 1.3 includes JNDI and
three service providers (listed below). These packages
are also available separately
for use with the JDK 1.1.x and the Java 2 SDK, v 1.2.
JNDI Tutorial - A tutorial introduction to the
JNDI technology with programming examples.
To use JNDI with a particular naming or directory service, you need a
JNDI service provider, which is a module that plugs in
beneath the JNDI API to access the naming or directory service. The
Java Software Web site maintains a list of
service providers available
Java 2 SDK, v 1.3 includes the following service providers:
