JNDI / Java Naming Directory Interface for Not Yet Techies

"Computer Careers: Using This Java Tool for Connecting With People and Computers Through Other Naming Services"

by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career

JNDI / Java Naming Directory Interface provides Java applications a standard, pre-written way of accessing various naming services. It is necessary for enterprise-size software programs and those using distributed programs, where the program must run on multiple computers often in separate locations. When you have such large scale computing, the programs and hardware involved must know where and how to find all the other components on the network. JNDI / Java Naming Directory Interface is therefore part of the Java Enterprise Application Programming Interface (API).

JNDI / Java Naming Directory Interface consists of three basic parts:

A set of generic interfaces that encapsulate common operations on naming services such as DNS (Domain Naming Service) and Lightweight Directory Access Protocol (LDAP).

JNDI / Java Naming Directory Interface has the javax.naming and javax.naming.directory packages for this

The second part of JNDI / Java Naming Directory Interface is the generic way to make a connection to the naming service. This CONTEXT interface is the most important.

The third part of JNDI / Java Naming Directory Interface is the "device-driver" model for naming services such as Java's RMI (Remote Method Invocation), Enterprise JavaBeans (EJB), Common Object Request Broker Architecture (CORBA), LDAP, DNS, file systems, Novell Directory Services and Network Information System (NIS).
