029     * A server-side JNDI provider implementation of {@link InitialContextFactory}.
030     * This class can be utilized via JNDI API in the standard fashion:
031     * <p>
032     * <code>
033     * Hashtable env = new Hashtable();
034     * env.put( Context.PROVIDER_URL, "ou=system" );
035     * env.put(
036     * Context.INITIAL_CONTEXT_FACTORY, "org.apache.directory.server.core.jndi.CoreContextFactory" );
037     * InitialContext initialContext = new InitialContext( env );
038     * </code>
039     * <p>
040     * Unfortunately, {@link InitialContext} creates a new instance of
041     * {@link InitialContextFactory} implementation everytime it is instantiated,
042     * so this factory maintains only a static, singleton instance of
043     * {@link DirectoryService}, which provides actual implementation.
044     * Please note that you'll also have to maintain any stateful information
045     * as using singleton pattern if you're going to extend this factory.
