				This example reads an object's schema from the directory. 
				    try {
				        // Get context containing class definitions for cn=Ted Geisel entry
				        DirContext tedClasses = ctx.getSchemaClassDefinition("cn=Ted Geisel, ou=People");
				    
				        // Enumerate class definitions
				        NamingEnumeration enum = tedClasses.search("", null);
				        while (enum.hasMore()) {
				            DirContext entry = (DirContext)enum.next();
				            process(entry);
				        }
