Java Naming and Directory Interface

JNDI est système d'annuaire générique. Il sait gérer “out-of-box” : LDAP, DNS, NIS, NDS, RMI et CORBA.

• javax.naming

Manipulation des associations.

• javax.naming.directory

Manipulation des répertoires.

• javax.naming.event

Traitement des évènements en provenance de l'annuaire.

• javax.naming.ldap

API spécialisée pour les annuaires compatibles LDAP.

• javax.naming.spi

API de programmation des pilotes JNDI.
