Web Services Description Language (WDSL), originally developed by IBM, Microsoft, and others, is an XML format for technical description of Web services. In this tutorial, Mike Olson and Uche Ogbuji introduce WSDL4Py, an open-source Python library for WSDL 1.1 hosted by IBM developerWork’s open-source zone. Usage of the library is explained, as well as discussion of its development.

This document presents my work as part of course COSC 4080 during fall 2002, under the supervision of Professor Jonathan Ostroff. The initial purpose of the project was to write a reusable component to store Eiffel objects in XML format, and also to investigate a new product from Eiffel Software, namely Eiffel Envision.

Eiffel Envision is a plug-in for Visual Studio.NET that facilitate the writing, debugging and testing of Eiffel code in Visual Studio.NET. Needless to say, the integration between Eiffel and the .NET Framework (hereinafter referred to as Eiffel.NET) is not just at the GUI level. Eiffel is now one of the few languages that are .NET compatible. This means that programmers can compile Eiffel code to run on the .NET Common Language Runtime (more on this issue in the next section).

The rapid advent of “Web 2.0” applications has unleashed new HTTP traffic patterns which differ from the conventional HTTP request-response model. In particular, asynchronous pre-fetching of data in order to provide a smooth web browsing experience and richer HTTP payloads (e.g., Javascript libraries) of Web 2.0 applications induce larger, heavier, and more bursty traffic on the underlying networks. We present a traffic study of Web 2.0 applications including Google Maps, modern Web-email, and social networking Web sites, and compare them with all HTTP traffic. We highlight the key differences of Web 2.0 traffic from traditional HTTP traffic through statistical analysis. As such our work elucidates the changing face of one of the most popular application on the Internet: The World Wide Web.

Over the last 12 years, Microsoft Corporation has developed a successful operating system for mobile devices based on Windows CE, currently known as Windows Mobile. The Windows Mobile deliverable consists of (1) a particular set of Windows CE components, (2) a logo test kit requirements document, (3) a set of light weight middleware applications, and (4) commercialization components, such as drivers and value-added services provided by OEMs and Mobile Operators. Microsoft licenses the Windows Mobile OS to third parties, (generally OEMs and MOs), who commercialize and sell the operating system as part of a device and service offering.

In a few short months, Ajax has moved from an obscure and rarely used technology to the hottest thing since sliced bread.
This article introduces the incredibly easy-to-use Ajax support that is part of the Ruby on Rails web application framework. This is not a step-by-step tutorial, and I assume that you know a little bit about how to organize and construct a Rails web application. If you need a quick refresher, check out Rolling with Ruby on Rails, Part 1 and Part 2.

This article shows you how a Java™ 2 Platform, Enterprise Edition (J2EE) application was enhanced with an Ajax-style architecture by using the IBM® WebSphere® Application Server Feature Pack for Web 2.0. Learn how to combine Ajax-style architectures with an existing application without having to rewrite the entire Web application. You’ll also discover some ideas on how to apply the Web 2.0 Feature Pack to your own J2EE applications for IBM WebSphere Application Server. The “Plants by WebSphere” application is among a number of samples that are provided with the IBM WebSphere Application Server Feature Pack for Web 2.0.

XML is a text based programming language. Therefore, the code can be written in a standard text editor. There are applications available specifically written for XML, but I have always used an enhanced shareware version of Notepad. If code is saved with a txt extension, rename with an xml extension. XML gauges usually consist of the xml file and bmp (bitmap) files, although gauges without bitmaps are quite common.

Cisco CVP VoiceXML software has been designed to be easy to use but highly extendable. While the software provides enough to produce high quality voice applications out of the box, many users will want to extend the functionality of the software by building custom components that perform very specific tasks. This document describes the processes and application programming interfaces (APIs) provided for a developer to construct and deploy these components.
