WK13 - Adobe Flex

What's Flex?

Flex was initially released as a J2EE application or JSP tag library that compiles MXML and ActionScript on-the-fly into Flash applications (binary SWF files). Later versions of Flex support the creation of static files that are compiled at authoring time and can be deployed online without the need for a server license.

The goal of Flex is to allow Web application developers to quickly and easily build rich Internet applications. In a multi-tiered model, Flex applications serve as the presentation tier.

Flex features development of graphic user interfaces using an XML-based language called MXML. Flex comes with various components and features that make capabilities such as web services, remote objects, drag and drop, sortable columns, charting/graphing, built in animation effects, and other interface interactions simple. Since the client only loads once, application workflow is significantly improved versus HTML based applications (eg. PHP, ASP, JSP, CFMX) which require executing templates on the server with every action. Flex's language and file structure are seeking to decouple application logic from design.

The Flex server also acts as a gateway to allow the client to communicate with XML Web Services and Remote Objects (such as Coldfusion CFCs, Java Classes, and anything else that supports the Action Message Format).

Commonly mentioned as alternatives to Flex are OpenLaszlo, Ajax and Windows Presentation Foundation technologies.

Flex Application Development Process

  1. Define an application interface using a set of pre-defined components (forms, buttons, and so on)
  2. Arrange components into a user interface design
  3. Use styles and themes to define the visual design
  4. Add dynamic behavior (one part of the application interacting with another, for example)
  5. Define and connect to data services as needed
  6. Build the source code into a SWF file that runs in the Flash Player

WK12 - Sematic Web ? Web 3.0 ?

Web 3.0
Web 2.0 came to describe almost any site, service, or technology that promoted sharing and collaboration right down to the Net's grass roots. That includes blogs and wikis, tags and RSS feeds, and Flickr, MySpace and YouTube. Because the concept blankets so many disparate ideas, some have questioned how meaningful—and how useful—it really is, but there's little doubt it owns a spot in our collective consciousness. Whether or not it makes sense, we now break the history of the Web into two distinct stages: Today we have Web 2.0, and before that there was Web 1.0.
Which raises the question: What will Web 3.0 look like?
Yes, it's too early to say for sure. In many ways, even Web 2.0 is a work in progress. But it goes without saying that new Net technologies are always under development—inside universities, think tanks, and big corporations, as much as Silicon Valley start-ups—and blogs are already abuzz with talk of the Web's next generation.
To many, Web 3.0 is something called the Semantic Web, a term coined by Tim Berners-Lee, the man who invented the (first) World Wide Web. In essence, the Semantic Web is a place where machines can read Web pages much as we humans read them, a place where search engines and software agents can better troll the Net and find what we're looking for. "It's a set of standards that turns the Web into one big database," says Nova Spivack, CEO of Radar Networks, one of the leading voices of this new-age Internet.

Semantics and Search
The Semantic Web, like Web 2.0, is a nebulous concept. "Considering that the very word semantic is all about meaning, it's ironic that the term Semantic Web is so ill defined," says Radar Networks' Spivack. Some, like Spivack, fall into the Berners-Lee camp. Others, like AdaptiveBlue's Iskold, believe in the artificial-intelligence method. And then there are the others: the semantic searchers.
Rather than providing automatic information retrieval, semantic search engines seek to improve on the Google-like search model we've grown so accustomed to. The idea is to move beyond mere keyword searches to a better understanding of natural-language queries. "Right now, search engines can't tell the difference between Paris Hilton and the Hilton in Paris," says Jeff Bates, cofounder of Slashdot, one of the driving forces behind Web 2.0. "There's millions of dollars being spent trying to better optimize search, and that's a big part of what the Semantic Web will be."
This kind of natural-language processing has been in development for years, but it, too, has found its way onto the public Web. Several start-ups, including Powerset and TextDigger, are hard at work on semantic search engines based on the open-source academic project WordNet. It should be noted, however, that natural-language search could very well play a role in the Berners-Lee Semantic Web. His is merely a framework to enable all sorts of apps, and semantic search might be one of them.

A Web Beyond Words
Though Web 3.0 is most often associated with the Semantic Web, the two are far from synonymous. Countless other concepts are poised to play a role in our online future, and many go beyond semantics, using space, images, and sound.
One possibility is the so-called 3D Web, a Web you can walk through. Many see this as an extension of the "virtual worlds" popping up on today's Internet. In the future, they say, the Web will be one big alternate universe reminiscent of Second Life and But others scoff at this notion, claiming it's just a less-efficient version of today's Internet. They see the 3D Web not as an alternate universe but as a re-creation of our existing world. On the 3D Web, you could take a virtual stroll through an unfamiliar neighborhood shopping for houses or visit famous sites you've never seen. Google Earth already offers an experience not far removed from this. "Today, with a service like Google Earth, you can zoom in on Seattle and see how tall the buildings are," says Syracuse University's Lankes. "It really isn't that much of a leap to actually put you, or your avatar, in Seattle and let you walk around."
The trouble is, 3D only goes so far. It doesn't enhance the very 2D world of words, pictures, and video. For many, the more interesting idea is a mediacentric Web, offering not just language-based search but pure media search. Today we depend on keywords even when searching for images, videos, and songs—a woefully inadequate system. Companies like Ojos and Polar Rose are working to reinvent media search, hinting at a world where we search for media with other media—not just keywords (see "Look Ma, No Keywords!" opposite).
Then there's the Pervasive Web, a Web that's everywhere. Today's Web already extends beyond the desktop, to cell phones and handhelds, but it might extend even further—into our everyday surroundings. At the MIT Media Lab, Maes is toying with the idea of Web-connected bathroom mirrors. As you brush your teeth in the morning, there's the latest news. Meanwhile, with his blog, the End of Cyberspace, Alex Soojung-Kim Pang of the Institute for the Future envisions the Web automating much of what goes on in the home. Your windows, for instance, could automatically open when the weather changes. With help from mesh networks—wireless networks consisting of tiny nodes that can route data to and from almost anywhere—the possibilities are nearly endless.

WK 10 - What's make J2EE lower cost development?

Apache Struts is an open-source framework for developing Java EE web applications. It uses and extends the Java Servlet API to encourage developers to adopt a model-view-controller (MVC) architecture. It was originally created by Craig McClanahan and donated to the Apache Foundation in May, 2000. Formerly located under the Apache Jakarta Project and known as Jakarta Struts, it became a top level Apache project in 2005.
Apache Ant is a software tool for automating software build processes. It is similar to make but is written in the Java language, requires the Java platform, and is best suited to building Java projects.
The most immediately noticeable difference between Ant and make is that Ant uses XML to describe the build process and its dependencies, whereas make has its Makefile format. By default the XML file is named build.xml.
Ant is an Apache project. It is open source software, and is released under the Apache Software License.

The Spring Framework provides solutions to many technical challenges faced by Java developers and organizations wanting to create applications based on the Java platform. Because of the sheer vastness of the functionality that is offered it can be hard to distinguish the major building blocks the framework is composed of. The Spring Framework is not exclusively linked to the Java Enterprise platform although its far-reaching integration in this area is an important reason for its popularity.
The Spring Framework is probably best known for offering features required to effectively create complex business applications outside of the programming models that historically have been dominant in the industry. Next to that it is also credited for introducing previously unfamiliar functionalities into today's mainstream development practices, even beyond the Java platform.
This amounts to a framework that offers a consistent model and makes it applicable to most application types that are created on top of the Java platform today. The Spring Framework is considered to implement one way of working based on best practices and industry standards and making it available to many domains in Java.

Eclipse is an open-source, platform-independent software framework for delivering what the project calls "rich-client applications", as opposed to "thin client" browser-based applications. So far this framework has typically been used to develop Integrated Development Environments (IDEs), such as the Java IDE called Java Development Toolkit (JDT) and compiler (ECJ) that comes as part of Eclipse (and which are also used to develop Eclipse itself). However, it can be used for other types of client application as well, such as the BitTorrent client Azureus.
Eclipse is also a community of users, constantly extending the covered application areas. An example is the recently created Eclipse Modeling Project, covering most areas of Model Driven Engineering.

NetBeans refers to both a platform for the development of Java desktop applications, and an integrated development environment (IDE) developed using the NetBeans Platform.
The NetBeans Platform allows applications to be developed from a set of modular software components called modules. A module is a Java archive file that contains Java classes written to interact with the NetBeans Open APIs and a manifest file that identifies it as a module. Applications built on modules can be extended by adding new modules. Since modules can be developed independently, applications based on the NetBeans platform can be easily and powerfully extended by third party developers.

As we know LAMP stands for Linux, Apache, MySQL, PHP, an alternative dynamic web platform, WISA is no doubt another good choice. WISA stands for Windows, IIS (Internet Information Services), MS SQL, and ASP.

The OS is platform on which all the other components run. Windows is easier to use, however, advanced controls needed to administer a dynamic web-site are often buried or only available by modifying configuration files. For small websites, the hosting server is not allowing us to access to OS level controls. For large websites, you have your own dedicated machine, or located in-house. So the choosing is based on other components we prefer.

The web server is the program that takes request for pages from a browser, interprets the request, and returns the results. IIS and Apache both are free. IIS is tightly integrated with Windows, and is easy to install, and is part of the default installation of Windows 2000/2003. Apache is open-source, meaning to advanced programmers can customize the way it runs and have more flexibility with if. Generally speaking, Apache is more secure than IIS, but its security features can sometimes be difficult to configure.

The database stores information that can be retrieved, stored, and manipulated by the scripting language. MySQL is a free database that can run on all OS. MS SQL costs $5000, can only runs on Windows, and is considered an enterprise-level database. MySQL is not as powerful as MS SQL, but is sufficient to almost all web application. If the difference in price may not be a factor in the decision if your website is to be hosted, as this is a cost to the hosting company. MS SQL is recommended while you anticipate using the database for non-web applications that need massive amounts of power, or if you are incorporating the features that are not available on MySQL.

Script is requested by a browser, the web server transfers control to a script engine which reads a program written in scripting language. PHP is a free scripting language and offers many OO features, integrated tightly with HTML, and is similar to other languages such as C++ and JavaScript. Active Server Pages (ASP) is not actually a scripting language, but is a Microsoft Technology that allows existing scripting languages to be used in a web context. ASP/VB is often said to be easier to program in than PHP. PHP has more standard features than ASP, most of which are open source such as shopping carts and web forums. However, to get functionalities in ASP one must purchase third party modules. The features on the free PHP are often better than ASP packages, but may be difficult to install and may have incomplete documentation.

In summary, I would recommend LAMP for most web sites because of its cost, since PHP’s simple web integration, and Apache’s security. I would recommend WISA for enterprise-level sits because of MS SQL Server’s raw power and Microsoft’s support services.

WK8 - A Full list of Ajax Toolkit/Framework/Libary Survey

License: Apache 2
Description: AjaxAnywhere is a simple way to enhance an existing JSP/Struts/Spring/JSF application with AJAX. It uses AJAX to refresh "zones" on a web page, therefore AjaxAnywhere doesn't require changes to the underlying code, so while it's more coarse than finely-tuned AJAX, it's also easier to implement, and doesn't bind your application to AJAX (i.e., browsers that don't support AJAX can still work.). In contrast to other solutions, AjaxAnywhere is not component-oriented. You will not find here yet another AutoComplete component. Simply separate your web page into multiple zones, and use AjaxAnywhere to refresh only those zones that needs to be updated.
Less JavaScript to develop and to maintain. Absence of commonly accepted naming convention, formatting rules, patterns makes JavaScript code messier then Java/JSP. It is extremely difficult to debug and unit-test it in multi-browser environment. Get rid of all those complexities by using AjaxAnywhere.
Easy to integrate. AjaxAnywhere does not require changing the underlying application code.
Graceful degradation and lower technical risk. Switch whenever you need between AJAX and traditional (refresh-all-page) behaviour of your web application. Your application can also support both behaviors.
Free open source license.
AxajAnywhere? is not as dynamic as pure-JavaScript AJAX solutions. Despite that AjaxAnywhere will probably cover your basic needs, to achieve certain functionality you might need to code some JavaScript.
Today, you can only update a set of complete DHTML objects without breaking then apart. For example, you can update a content of a table cell or the whole table, but not the last row, for example. In later versions, we plan to implement partial DHTML update, as well.

License: Apache 2.0
Description: ajaxCFC is a ColdFusion? framework meant to speed up ajax application development and deployment by providing developers seamless integration between JavaScript and ColdFusion?, and providing built-in functions to quickly adapt to any type of environment, security, and helping to overcome cross-browser compatibility problems.
ajaxCFC is designed as ColdFusion? components, following the best practices of object oriented programming and design patterns. Programming with ajaxCFC involves extending components and creating your own ajax facades.
Works with ColdFusion? MX 6.0, 6,1, 7.0, Scorpio, and BlueDragon?.
Integration with Model-Glue and MachII?, two of the most popular MVC frameworks widely used by the ColdFusion? community.
Supports many browsers including FF/Moz, IE5.5+, Safari/Konq, Opera and IE with Active-X turned off via iframe fallback
Automatically handles complex object transmitted from the client to the server and vice versa.
Optional use of XML Sockets to push data from the server.
Built-in security add-ons.
Hosted now by Adobe's RIAForge

AjaxTags component of Java Web Parts
License: Apache 2
Description: AjaxTags was originally an extended version of the Struts HTML taglib, but was made into a generic taglib (i.e., not tied to Struts) and brought under the Java Web Parts library. AjaxTags is somewhat different from most other Ajax toolkits in that it provides a declarative approach to Ajax. You configure the Ajax events you want for a given page via XML config file, including what you want to happen when a request is sent and when a response is received. This takes the form of request and response handlers. A number of rather useful handlers are provided out-of-the-box, things like updating a
, sending a simple XML document, transforming returned XML via XSLT, etc. All that is required to make this work on a page is to add a single tag at the end, and then one following whatever page element you want to attach an Ajax event to. Any element on a page can have an Ajax event attached to it. If this sounds interesting, it is suggested you download the binary Java Web Parts distro and play with the sample app. This includes a number of excellent examples of what AjaxTags can do.
There is no Javascript coding required, unless you need or want to write a custom request/response handler, which is simply following a pattern.
Very easy to add Ajax functions to an existing page without changing any existing code and without adding much beyond some tags. Great for retroactively adding Ajax to an app (but perfect for new development too!)
Completely declarative approach to Ajax. If client-side coding is not your strong suite, you will probably love AjaxTags.
Has most of the basic functions you would need out-of-the-box, with the flexibility and extensibility you might need down the road.
Cross-browser support (IE 5.5+ and FF 1.0.7+ for sure, probably some older versions too).
Is well-documented with a good example app available.
Because it's a taglib, it is Java-only.
Doesn't provide pre-existing Ajax functions like many other libraries, things like Google Suggests and such. You will have to create them yourself (although AjaxTags will make it a piece of cake!). Note that there are some cookbook examples available that shows a type-ahead suggestions application, and a double-select population application. Check them out, see how simple they were to build!
AjaxTags says absolutely nothing about what happens on the server, that is entirely up to you.
Might be some slight confusion because there is another project named AjaxTags at SourceForge. The AjaxTags in Java Web Parts existed first though, and in any case they have very different focuses. Just remember, this AjaxTags is a part of Java Web Parts, the other is not.

Description: s@rdalya, is a cross-browser interface that aims to make dynamic HTML programming easy and fun. It is a cross-browser compatible system which is designed to work in all DOM-supporting browsers.
Though the developer doesn't test on a Mac, I encountered no problems viewing all of the many DHTML samples he provides. Sardalya includes Ajax functions as well as a comprehensive DOM-based DHTML library.
The library received and "A grade" from
In its blog, the developer says that the next version of the library will include:
A better AJAX integration.
And more objects to play with(such as Effect object for scheduled transitions such as background fades, or ModalDialog? object which generates a DOM generated modal dialog, which is a cross-browser DOM-implementation of IE's modal dialog, which is not being used much because it is vendor-specific and not supported in other browsers.
Flexible, easily extendible.
Works in almost any modern browser.
Independent of OS.
Lightweight when you consider what is does.
Since it is being constantly developed, the documentation may not be in sync with the most recent version. However viewing the sources of examples are adequate to learn how to use the API.

License: MIT
Description: provides you with easy-to-use, compatible and, ultimately, totally cool! JavaScript libraries to make your web sites and web applications fly, Web 2.0 style.

Well-designed site actually has some reference materials attached to each section.
Lots of neat visual effects.
Simple and easy to understand object-oriented design.
Although developed together with Ruby on Rails it's not dependent on Rails at all, has been used successfully at least in Java and PHP projects and should work with any framework.
Because of the large user-group coming from Ruby on Rails it has very good community support.

Visual WebGui (The .NET answer to Google's GWT that extends WinFormsover ASP.NET)
Visual WebGui? (VWG) is an open source AJAX framework with a growing community that extends ASP.NET with the WinForms? programming model.
VWG provides an alternative to ASP.NET's page model in the form of WinForms? forms and form events. Since VWG, like most .NET AJAX frameworks, is implemented using an IHttpHandler?, it can still interact with ASP.NET pages enabling usage of VWG within an existing ASP.NET site.
VWG features:
AJAX application development using WinForms? development patterns and practices with no prior AJAX (or web development) skills.
WinForms? controls (most of .NET 2.0 controls) implemented for VWG.
Ability to create custom controls (including full inheritance).
Ability to interoperate with existing ASP.NET controls and pages.
Ability to customize control behavior and appearance.
.NET 1.x/2.0 support.

VWG unlike GWT:
Does not generate JavaScript code – debugging is done within the server-based .NET code that executes in runtime.
Does not run application logic on the client – all processing is done on the server.
Does not expose unnecessary services to the client – server sends UI updates / client sends user event queues.
Results in a thin client rather than a fat client.
Is based on a familiar WinForms? object model.
Is provided with full WinForms? like design time capabilities.
