Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Hashtable<String, String> env = new Hashtable<String, String>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "YourURL");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, "userDN");
    env.put(Context.SECURITY_CREDENTIALS, "secret");
    EventContext ctx = (EventContext) (new InitialContext(env).lookup("ou=People"));

    NamingListener listener = new SampleNCListener();

    ctx.addNamingListener("cn=John", EventContext.ONELEVEL_SCOPE, listener);
}

From source file:RegUnsol.java

public static void main(String[] args) {

    // Set up environment for creating 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 {//from   w w  w .ja v a 2s . c  om
        // Get event context for registering listener
        EventContext ctx = (EventContext) (new InitialContext(env).lookup("ou=People"));

        // Create listener
        NamingListener listener = new UnsolListener();

        // Register listener with context (all targets equivalent)
        ctx.addNamingListener("", EventContext.ONELEVEL_SCOPE, listener);

        // Wait 1 minutes for listener to receive events
        try {
            Thread.sleep(60000);
        } catch (InterruptedException e) {
            System.out.println("sleep interrupted");
        }

        // Not strictly necessary if we're going to close context anyhow
        ctx.removeNamingListener(listener);

        // Close context when we're done
        ctx.close();

    } catch (NamingException e) {
        e.printStackTrace();
    }
}
