Enumerates the names bound in the named context, along with the objects bound to them.

Usage

From source file:ListBindings.java

public static void main(String[] args) {

    // Set up the environment for creating the initial context
    Hashtable<String, Object> env = new Hashtable<String, Object>(11);
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://localhost:389/o=JNDITutorial");

    try {//w  w w.  j av a 2  s . c  o m
        // Create the initial context
        Context ctx = new InitialContext(env);

        // Get listing of context
        NamingEnumeration bindings = ctx.listBindings("ou=People");

        // Go through each item in list
        while (bindings.hasMore()) {
            Binding bd = (Binding) bindings.next();
            System.out.println(bd.getName() + ": " + bd.getObject());
        }

        // Close the context when we're done
        ctx.close();
    } catch (NamingException e) {

    }
