The Java™ Naming and Directory Interface (JNDI) is part of the JavaSoft platform application program interface (API). With JNDI, you can connect seamlessly to multiple naming and directory services. You can build powerful and portable directory-enabled Java applications by using this interface.
JavaSoft developed the JNDI specification with leading industry partners, including IBM®, SunSoft, Novell, Netscape, and Hewlett-Packard Co.
Note: The i5/OS™ Java Runtime Environment (JRE) and the versions of the Java 2 Platform, Software Development Kit (J2SDK) offered by the IBM Developer Kit for Java include the Sun LDAP provider. Because i5/OS Java support includes the Sun LDAP provider, that support no longer includes the ibmjndi.jar file. The ibmjndi.jar file offered an IBM-developed LDAP service provider for older versions of the J2SDK.
