Class JndiExamples

java.lang.Object

net.jrodolfo.java_evolution.java03.jndi.JndiExamples

public class JndiExamples
extends Object

Demonstrates Java Naming and Directory Interface (JNDI), included in J2SE 1.3.

Production JNDI providers often point to LDAP, DNS, RMI registries, or application-server resources. This example uses a tiny in-memory provider so the provider model, names, contexts, bindings, and lookups can be exercised without external infrastructure.
