Building AJAX JSF Components

pdfmanual — Fri, 23 Dec 2011 18:50:13 +0000

AJAX is an acronym for Asynchronous JavaScript and XMLHttpRequest. The XMLHttpRequest object is a de facto standard object provided by browser-based JavaScript implementations, and when used in an asynchronous fashion it allows the page author to communicate with the Web server in the background of the page, without giving the user any visual cue that this communication is occurring. The Web browser’s “spinner” does not spin, the hourglass mouse pointer does not appear, and the browser does not “block” in any way. Using the XMLHttpRequest in concert with standard JavaScript and DOM APIs allows the page author to dynamically update the page with arbitrary server-supplied data.

The first implementation of an API for background-based asynchronous communication with the server came from Microsoft in the form of their XMLHTTP ActiveX object. This API was later emulated in a compatible fashion by Netscape and other browsers, enabling users to write Web applications that use XMLHttpRequest and still run on a variety of browsers while minimizing the amount of browser-dependent code required. It has taken a long time to arrive at the point where most users can be assumed to have a browser capable of AJAX, but as of this writing it’s a safe bet.

Even though these technologies had been around for several years their widespread use in Web applications didn’t catch on until Google showed the world how powerful a first-class application of AJAX practices can be. The introduction in 2004 of Google’s e-mail service, which makes heavy use of XMLHttpRequest techniques, inspired a renaissance of interest in JavaScript that ultimately led to what people now call AJAX. Google’s map service also leverages AJAX techniques to good effect. As of this writing, the field of innovation is still wide open and the best practices have yet to fully emerge.

AJAX Application Design: Tips & Tricks

pdfmanual — Fri, 23 Dec 2011 18:47:01 +0000

The AJAX developers need to keep in mind some crucial points when they are developing and designing applications. These facts are applicable from small to large applications. Personally I believe every AJAX developer should know all these facts for developing more robust and reliable applications. Okay, let us see them now.

The Back Button and Bookmarks are going to break down
The back button of the browser is dependent on the history object. Whenever you browse successive pages, these pages are loaded and browser’s history object saves data so that you can go back. But when you are using JavaScript to control the content and behavior of the page, the back button and bookmarks will not work any more.
So, you may develop and set your own JavaScript back button so that the user can navigate to a previous page.

There are ways to solve this problem although pretty complex.
Use Visual Cues
In most cases, AJAX applications work behind the scene. The application may take long time to load or to process lots of data. In such times, it is hard for the user to understand whether the connection with the server is dead or it is still loading and/or working. The user will feel comfortable if you can use a gif image to show that the application working and/or busy. It is common to use a rotating hourglass until data is fully loaded. You can make it appear until the data is loaded and disappear whenever all data are loaded.

document.getElementById(“loading”).style.visibility = “visible”;
document.getElementById(“loading”).style.visibility = “hidden”;

Instead of a rotating hourglass, you can also keep a blue line creeping from left to right slowly.
Let the User Control the Application
It is meaningless if the user types a wrong word and your application immediately stores it in the database. This may annoy the user easily since every user will want to correct it before it is saved in the database. It is a better way to give the user a way so that she herself can store the data when she is ready to do so. Let the user feel comfortable with your application and do not bug her with too much client server interactions.
Also remember to keep a way so that the users can undo errors they have done.

Test Your Application in Different Browsers
Even the most used two browsers Internet Explorer and Firefox do not handle the same coding in the same way. To make your coding cross browser supported, you need to be careful from very beginning. After you develop a part and test it using the commonly used browsers or by the browser the application will be used is a good practice. The more browsers support your application, the more robust and reliable you application is.

AJAX Wake on LAN

pdfmanual — Fri, 21 Oct 2011 20:39:36 +0000

AJAX Wake on LAN Michael Kopps Semester Project CS301: Web Programming Dr. Chow Purpose As an institution of higher education, the University of Colorado at Colorado Springs has a great number of computing needs placed upon it. One pressure is to increase the sustainability of the campus as a whole, and the waste of electrical energy is a major factor that affects the environmental footprint of the university. With a large amount of computers on campus, it is wise to

implement power management to place computers in a suspend or reduced power state when not in use. Another factor is the need to provide a consistent and reliable means of data storage and access for whatever sort of research and learning that takes place on the campus. This means that the computers must be constantly up to date with security patches and clean of malicious software that can decrease the performance and even leak a valuable piece of research. Performing this requirement requires the computers to be on afterhours, when most computers are not in use. These two seemingly contradictory requirements present a massive challenge to the Information Technology department on the UCCS campus. In an effort to meet this challenge, a technology called Wake on LAN (WOL) was developed to wake computers connected to a network so they can be administered, even after they have been turned off by the normal user. To make WOL easier to use and manage, a web based interface utilizing asynchronous JavaScript and XML (AJAX) was developed. This emerging technology has transformed the internet from a quite static place to a much more dynamic and rich environment. AJAX Overview The beginnings of what it…

Introduction to Database Programming using PHP and MySQL Revision 1.1 June 14, 2010 by Aloysius Indrayanto (C) 2010 AnemoneSoft.com This document is multi-licensed under the Creative Commons Attribution Share-Alike (CC-BY-SA) license version 3.0 and the GNU Free Documentation License (GNU FDL) version 1.3 or later. Introduction to Database Programming using PHP and MySQL Page 1 of 12 1. Introduction LAMP (an acronym for Linux, Apache, MySQL, and PHP) is basically the most popular solution stack to deliver a general-purpose web

and application server. A solution stack is a full set of software components bundled together to provide a specific solution. Basically, the exact combination of software included in LAMP can be modified, depending on the need of the developer. For example, PHP can be replaced with Python, Perl, or other scripting language. In MS Windows, the package is called WAMP. In Mac OS, it is called MAMP. In Solaris, it is called SAMP. In OpenBSD it is called OpAMP, etc. PHP: Hypertext Preprocessor was invented by Rasmus Lerdorf in 1995. PHP is both a general-purpose programming language and a scripting language. PHP can be used to develop general-purpose applications (with and without graphical interface) as well as dynamic web pages or web applications. PHP is an interpreted language. Currently, PHP is maintained by The PHP Group. PHP is free and open source. MySQL Community Server is a free and open source RDBMS (Relational Database Management System) that runs as a server to provide a multi-user database system. The original MySQL was developed by Michael Widenius. Currently, MySQL is owned and sponsored by Sun Microsystems, a subsidiary of Oracle Corporation. MySQL has been used in large-scale products, such as Wikipedia, Google,…

MySQL Tutorial – University of Ibadan

pdfmanual — Sat, 06 Aug 2011 17:32:11 +0000

This tutorial is inspired by the examples of this book : MySQL™ The definitive guide to using, programming, and administering MySQL 4.1 and 5.0 Third Edition By Paul DuBois – SAMS March 2005 Design & Conception: P.K helped by A.D, L.W & S.S. A MySQL Tutorial Basic Database Terminology Many relational database concepts are really quite simple. In fact, much of the appeal of relational databases stems from the simplicity of their foundational concepts. Structural Terminology Within the database world,

MySQL is classified as a relational database management system (RDBMS). That phrase breaks down as follows: • The database (the “DB” in RDBMS) is the repository for the information you want to store, structured in a simple, regular fashion: o The collection of data in a database is organized into tables. o Each table is organized into rows and columns. o Each row in a table is a record. o Records can contain several pieces of information; each column in a table corresponds to one of those pieces. • The management system (the “MS”) is the software that lets you use your data by allowing you to insert, retrieve, modify, or delete records. • The word “relational” (the “R”) indicates a particular kind of DBMS, one that is very good at relating (that is, matching up) information stored in one table to information stored in another by looking for elements common to each of them. The power of a relational DBMS lies in its capability to pull data from those tables conveniently and to join information from related tables to produce answers to questions that can’t be answered from individual tables alone. Here’s an example that shows how a relational…
