Build a pureXML and JSON application, Part 3: Create OpenSocial gadgets for pureXML
With the Web 2.0 technology of OpenSocial gadgets, developers can easily
include their applications in popular Web sites, such as iGoogle, MySpace, Hi5,
LinkedIn, and others. In this article, explore OpenSocial gadgets through hands-on construction of an application that leverages the pureXML
capability of DB2. This article is the last in a series of three that illustrates how to build a
pureXML application whose user interface is a gadget that you can deploy in any OpenSocial compliant
Web site. Follow the steps in this article to build a user interface that stores and retrieves the
JSON data described in the first article through JSON Universal Services created in the second article.

Leveraging pureXML in a Flex microblogging application, Part 3: Using pureXML Web services to publish microblog entries to an HTML page
The pureXML capabilities of IBM DB2 allow you to store XML natively in a database
without modification, while Adobe Flex applications can read XML directly and
populate Flex user interfaces. In this three-part article series, you will create
a microblogging application that takes advantage of pureXML, Web services, and
Adobe Flex; and even allows you to publish your microblogging updates on Twitter.
In Part 1 of the series, you learned about Web Services and how they are enabled
using DB2 pureXML as you created the microblog database and tested it. Part 2
tapped into Adobe Flex and ActionScript to create the user interface of your application. In this article, the final part of the series, you will learn how to use your pureXML Web Services to publish your microblog entries to an HTML page.

Developing a Web 2.0 application using the InfoSphere Business Glossary REST API
IBM InfoSphere Business Glossary enables users to create, manage, and share an enterprise vocabulary and classification system.
In version 8.1.1, the Business Glossary team introduced a REST API that makes
glossary content easier to consume by enabling the development of custom applications based on particular needs.
This article provides step-by-step instructions on how to develop a portable, dynamic
read-write widget that uses the IBM InfoSphere
Business Glossary REST API in conjunction with various Web 2.0 technologies.
The widget enables users to find terms, examine the term's details, and make basic edits.
Our goal is for InfoSphere Business Glossary customers to
use the knowledge gained through building this sample widget as inspiration
for using the REST API to create their own custom applications.
This article is intended for software engineers who are familiar with Web 2.0
technologies and product designers who can apply the tools provided here to real world situations.

Overcome security threats for Ajax applications
Asynchronous JavaScript + XML (Ajax), a key technology in Web 2.0, allows user interaction with Web pages to be decoupled from the Web browser's communication with the server. In particular, Ajax drives mashups, which integrate multiple contents or services into a single user experience. However, Ajax and mashup technology introduce new types of threats because of their dynamic and multidomain nature. Learn about the threats associated with Ajax technologies, and discover some best practices to avoid them.

The result is a back-and-forth that usually involves clicking a button, waiting for the server, clicking another button, and then waiting some more. With Ajax and the XMLHttpRequest object, you can use a request/response model that never leaves users waiting for a server to respond. In this article, Brett McLaughlin shows you how to create XMLHttpRequest instances in a cross-browser way, construct and send requests, and respond to the server.

In Parts 1 and 2 of this tutorial series, Uche Ogbuji has shown how to use Cascading Stylesheets (CSS) to display XML in browsers, presenting basic and advanced techniques. Although some people see XSLT and CSS as opposing technologies, they are actually very complementary. CSS cannot, and is not designed to, handle many XML rendering tasks. You can use XSLT for many such tasks, and even manage the CSS that is still used to fine-tune the presentation. This tutorial covers techniques for using XSLT to process XML in association with CSS.

This article looks at different ways to use the information submitted on an HTML form, in both older and more recent versions of PHP. It starts out by looking at individual values and builds to a page that can generically access any available form values.
