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

Usage

From source file:GetAttrs.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 {/*from   w w  w  .  j  a  v a2  s . co m*/
        // Create initial context
        DirContext ctx = new InitialDirContext(env);

        // Specify the ids of the attributes to return
        String[] attrIDs = { "sn", "telephonenumber", "golfhandicap", "mail" };

        // Get the attributes requested
        Attributes answer = ctx.getAttributes("cn=Ted Geisel, ou=People", attrIDs);

        // Print the answer

        // Close the context when we're done
