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

packages JNDI

  • 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.
