Creating a VAMP (Vista, Apache, MySQL, PHP) Setup With the abundance of communication between the browser and a server in these days of AJAX and JSON data interchange, there has never been a better time to get your own development web server set up so that you can test all those dynamic scripts you’re writing. This article will show you how to do it using some of the most popular software. Putting Apache in Jail In this conclusion to a six-part series on Apache configuration and installation, you will learn how to use chroot to put Apache in jail, how to prepare PHP to work in jail, and more.

Installing Apache In the second part to a six-part series on Apache installation and configuration, we will focus on selecting modules to install and begin to explore configuration and hardening.

Apache Installation and Configuration Apache is the most popular web server on the Internet, partly because it is open source. This popularity means that security is very important. Securing the application starts with the way you configure it. This article, the first of six parts, is excerpted from chapter two of Apache Security, written by Ivan Ristic (O'Reilly; ISBN: 0596007248). Copyright © 2006 O'Reilly Media, Inc. All rights reserved.

Apache Tapestry and Custom Components: DateInput Tapestry has many benefits, but perhaps one of the most important is that it makes creation of custom components very easy. In this article, I'll create a custom component to illustrate this point. Tapestry and AJAX: Autocompleter and InlineEditBox Although the term AJAX was coined not so long ago, AJAX-like functionality has already been available in Tapestry for quite some time. In Tapestry 4.0 we can use Tacos, a rich and interesting library of custom Tapestry components that includes a number of AJAX-driven components. Tapestry 4.1 has Dojo JavaScript library built into it, so it comes with some core AJAX-enabled components. PropertySelection and IPropertySelectionModel in Apache Tapestry We already encountered PropertySelection in one of the previous articles so we know that it is a Tapestry component used to display a drop-down list, allowing the user to choose one of multiple options. You might think that the way in which options are provided to this component (through its model binding) is somewhat cumbersome when all you need to do is select one of a few strings. However, PropertySelection was designed with a great deal of power and flexibility in mind, and I hope that today you will appreciate this. The DatePicker and Shell Components of Apache Tapestry In the previous article in this series we came to adding a component for accepting a date input, to specify the date of birth for the newly added celebrity. DatePicker, a standard Tapestry component, is an excellent choice for this, and we are going to learn today how to add a DatePicker to a page. Apache Tapestry: ASO and More Components We shall continue working on the CelebrityCollector application. The next step is to create a page for adding a new celebrity. While we create that page, I will introduce you to three more components that will add new capabilities to our application and help us get around certain problems. Apache Tapestry and DirectLink, IoC and DI Previously we began building our CelebrityCollector application. But right now it is a hollow shell. In this article we will use several new Apache Tapestry components to help us start filling in the details. Making a CelebrityCollector with Apache Tapestry: the For Component We are going to start a new project today, named CelebrityCollector. At first it will be very simple, but in the following articles we’ll be adding more and more functionality to it. Of course, the purpose at this stage of study is not to build a real-world application but to meet different Tapestry components and to learn various important concepts. Apache Tapestry and Listener Methods, Conditional Components and PageLink Today we continue to explore some of the most fundamental concepts of Tapestry while building one of the simplest Java Web applications. In the previous part of this tutorial we became familiar with properties of Tapestry pages and different ways to configure them. Now we’ll look into the details of writing listener methods. The Properties of Tapestry Pages In the previous part of this tutorial we started to build a new project, GuessTheWord. The project is very simple, but we are going to spend a lot of time working on it and experimenting with it. This is because the main aim is to learn a lot about the most basic concepts of Tapestry. For every important concept, I want to show you a number of options as to how it can be implemented and explain which option is good for what. A Closer Look at Simple Components in Apache Tapestry In the previous article, we took a look at some of the components that are used most often in Tapestry applications, and learned some important concepts related to them. At the end, we found that we needed three components for our example application. In this article, we will configure those components. We will also learn how to disable caching. Introducing Simple Components in Apache Tapestry In the previous article, you witnessed the interplay between a Tapestry page and its components (granted, we had only one simple component there, but you get my point). Page class, when rendering its page, finds any components mentioned in the template and asks those components to display themselves, as they know better how to do that. Components, in their turn, might need some information to display themselves, and they ask the page class to provide the necessary information by calling some of its methods. Creating Your First Tapestry Project In the previous article, we began moving from theory to practice by preparing our work place and setting up our system. In this article, we actually get our hands dirty (at least figuratively) by building our first Tapestry project. Book Review: The Apache Modules Book The Apache Modules Book is the latest open-source software development book from Prentice Hall. The book forms part of the Open Source Development Series from Prentice Hall, which includes other titles such as Understanding AJAX and Embedded Linux. Dan Wellman looks at this book chapter by chapter to see whether it's a worthy addition to an open source developer's library.
