The Java Naming and Directory Interface (JNDI) is an API
for directory service that allows clients to discover and
lookup data and objects via a name. Like all Java APIs that
interface with host systems, JNDI is independent of the
underlying implementation. Additionally, it specifies a
service provider interface (SPI) that allows directory
service implementations to be plugged into the framework.
The implementations may make use of a server, a flat file,
or a database; the choice is up to the vendor.
