A constructor chained from Properties keeps Hashtable fields uninitialized since they are not used.

Usage

From source file:RetrievingLdapName.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 {/*ww  w  .j ava 2s.  c  o m*/
        // Create initial context
        DirContext ctx = new InitialDirContext(env);

        NamingEnumeration answer = ctx.search("ou=People", null);

        // Print the answer
        while (answer.hasMore()) {
