The coming of Ajax was an important landmark in the history of Web 2.0. Ajax is a group of technologies that enable developers to build interactive, feature-rich web applications. Most of these technologies were available many years before Ajax itself. However, the advent of Ajax represents the transition of the web from static pages that need to be refreshed whenever data was exchanged to dynamic, responsive and interactive user interfaces.
In this article by Ayman Hourieh, you will learn about the following:
- Ajax and the benefits of using it in web applications.

When developing a Rails project, there are more things to do than the source code itself. We have to start, stop, and monitor our servers, generate code templates, run our test suites, install plug-ins and gems, generate documentation, keep control of to-do items, or run Rake tasks for different purposes—database migrations, for example. RadRails provides different Views for supporting these tasks that are a part of the development but not of the coding itself. And, of course, it does it so we can control everything from within the IDE without having to go back to the command-line interface. In this article by Javier Ramírez, we will see how to open a View. We will also look at the Documentation Views and the Servers View, which are available as part of the Rails default perspective, that is, you don't need to do anything special to open them.Read RadRails Views in full
This article deals with the Scalix Administration Console (SAC). This web interface is the central point of administration for the Scalix server. User, group, and resource management are done here as well as controlling services and settings. In this article by Markus Feilner, we will take a short tour through the interface, add a first user, and have a closer look at the configuration options available for him/her. Towards the end, we will test the account by logging into the web client, and sending (and receiving) emails.Read First Steps with Scalix Admin Console and Scalix Web Access in full

MySQL Workbench is a visual database design tool recently released by MySQL AB. The tool is specifically for designing MySQL database.
MySQL Workbench has many functions and features; this article by Djoni Darmawikarta shows some of them by way of an example. We’ll build a physical data model for an order system where an order can be a sale order or a purchase order, and then, forward-engineer our model into an MySQL database.Read Visual MySQL Database Design in MySQL Workbench in full
The fundamental goal of any given Simple Object Access Protocol (SOAP) processing framework is to deliver an incoming SOAP message to the target application. However, if we consider today's Web Services or any other application, just delivering the message to the application is not sufficient. We need to provide quality of service, such as reliability and security. To provide these features, most SOAP processing frameworks have the concept of pipes, where, any incoming or outgoing message goes through the pipe, and the pipe gets divided into smaller pieces. Each piece is known as an interceptor. "Handler" is the Apache terminology for "message interceptor". In this article by Deepal Jayasinghe, we will see how to write a simple handler, what is a Phase, different types of Phase, and invalid Phase rules.Read Handler and Phase in Apache Axis2 in full
The Java Database Connectivity (JDBC) API is used to access a SQL database from a Java application. JDBC also supports tabular data sources, such as a spreadsheet.
Oracle JDeveloper is a free Integrated Development Environment (IDE) for modeling, developing, debugging, optimizing, and deploying Java applications. JDeveloper 10g is used to develop J2EE applications comprising the JSPs, EJBs, Struts, Servlets, and the Java classes that may require accessing a database table in the Oracle 10g Database, or a third-party database. In this article by Deepak Vohra, we will see how to configure JDBC in the JDeveloper IDE.Read Configuring JDBC in Oracle JDeveloper in full
AJAX—it's the buzzword that hit the Web with a bullet in 2005, thanks to Jesse James Garrett, a user-experience expert who founded AdaptivePath.com. If you're totally new to AJAX, I'll just point out that; at its core, AJAX is nothing that scary or horrendous. AJAX isn't even a new technology or language!
With the help of this article by Hans-Jurgen Schumacher and Markus Staeuble, you should be able to build your own applications based on the ZK framework.

Traditionally, web hosts have had a difficult time offering efficient, highly secure web space for a multitude of customers. Generally, a host will provide cheap accounts on a shared server and offer virtual machines as a more expensive option for the more security-conscious site owners. In this article, Joshua Kramer will explain how to provide highly secure hosting for Python-based web applications in an efficient manner. With the popularity of applications such as Trac, Django, and TurboGears, Python-based web applications will become more prevalent in the future, and the concepts presented in this article will become more valuable.Read SELinux - Highly Secured Web Hosting for Python-based Web Applications in full
