Java Naming and Directory InterfaceTM
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 common way.JNDI Tutorial
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.
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 for JNDI.For More Information
