Use Ext, Aptana, and AIR to build desktop applications
While Rich Internet Applications and Web 2.0 have been all the rage, the latest
wave of emerging technologies are focusing on not only giving Web applications a
desktop-like feel but actually bringing them to the desktop. The Adobe Integrated
Runtime (AIR) has led the way, allowing Web application developers to leverage their
existing knowledge of HTML, CSS, JavaScript, Flash, and Flex to build powerful desktop
applications. In this tutorial, you will use the open source Aptana Studio IDE, the
Adobe AIR plug-in for Aptana, and the open-source JavaScript framework Ext. |

Build a RESTful Web service
Representational state transfer (REST) is a style of designing loosely coupled applications that rely on named resources rather than messages. The hardest part of building a RESTful application is deciding on the resources you want to expose. Once you've done that, using the open source Restlet framework makes building RESTful Web services a snap. This tutorial guides you step-by-step through the fundamental concepts of REST and building applications with Restlets. |

Use JRuby on Rails and XML to supercharge Ajax with a Java Application Server
The Ruby on Rails framework has handy XML features that will make developing
with and serving database data in XML format to your JavaScript applications easier
than ever. JavaScript also has built-in XML parsing capabilities that make it a snap
to receive and parse data in XML format. But what if you now want to hook into Java
applications without having to deploy another server? That's where JRuby comes in.
JRuby on Rails is the Java implementation of the Ruby on Rails framework and brings the benefits of Rails to Java programming by allowing deployment of Ruby apps to Java application servers. In this tutorial, you'll develop a JRuby on Rails application deployable to a Java application server that will serve database data in XML format to an Ajax client that you'll build for film lovers to manage their online films database. You'll also deploy a couple of Java Server Pages pages on the same Java application server to assist the Ajax client in adding and updating films. |

Mastering Grails: Many-to-many relationships with a dollop of Ajax
Many-to-many (m:m) relationships can be tricky to deal with in a Web
application. In this installment of Mastering Grails, Scott Davis shows you how to
implement m:m relationships in Grails successfully. See how they're handled by the
Grails Object Relational Mapping (GORM) API and the back-end database. Also find out
how a bit of Ajax (Asynchronous JavaScript + XML) can streamline the user interface. |

Web development. You have an alternative, however: Tapestry and
Wicket are component-oriented Web frameworks designed to create Web
applications. A simple example application implementing a to-do list workflow is
developed here, using Tapestry and Wicket technologies. |

Use an XML database in PHP and Java applications
Native XML databases have grown in popularity along with XML, because data
is stored as native XML, rather than through tables in a traditional database. Using
a native XML database means that a change to the schema requires minimal changes to
your code and no change to the database. PHP and Java(TM) developers can benefit greatly
from using native XML databases. In this tutorial, you will get quickly up to speed using a native XML database and see how to use it to benefit XML development. |

Build a mobile RSS reader
What good is a mobile computing environment if you can't keep track of your favorite news feeds on the go? Sure, you can use Android's browser to read your favorite Web sites, but it's unlikely the sites are optimized for a screen two inches high. And besides, then you'll miss the opportunity to integrate RSS or other XML data with other mobile applications to make your own mash-ups. This tutorial shows you how to use the Android Developer Tools to read, parse, and display XML data. |

Eclipse at eBay, Part 2: eBay's plug-ins in action
Eclipse has become the premier integrated development environment (IDE) for Java
developers everywhere. Eclipse is definitely not a one-size-fits-all system, though.
Its plug-in architecture allows you to add the features you need. This is even more
important in large organizations like eBay. Such organizations have very specific
needs. Eclipse makes it easy to not only tailor a solution to those needs but also to
scale that solution across a large organization. Here in Part 2 of a two-part "Eclipse
at eBay" series, we will look at some of the organizational needs of eBay and how it has
used Eclipse to fill those needs. We will concentrate on how eBay has used Eclipse, but
the beauty is that you can employ similar tactics for your organization. |

Eclipse at eBay, Part 1: Tailoring Eclipse to the eBay architecture
Eclipse's first claim to fame was as an integrated development environment (IDE)
for Java. Eclipse's plug-in architecture is a big reason for its success. There are
many popular plug-ins available, and it is very easy to create your own. These two
traits make Eclipse a perfect fit for systems with specialized architectures, such as
eBay. In this article, the first of a two-part series covering eBay's use of Eclipse,
we look at eBay's architecture and how eBay has tailored Eclipse to suit its
architecture. While the article focuses on eBay, you can use the lessons here to
tailor Eclipse to your system's architecture. |

Create your own information space with Ajax and del.icio.us
del.icio.us is a social bookmarking Web site that allows users to create and
share browser-independent bookmarks, accessible directly over the Internet, in ways
your browser won't allow. The traditional hierarchical organization of browser bookmarks is overhauled, allowing users to instead associate each and every bookmark with any number of descriptive tags. Imagine a single page where you and your friends can surf the Web and have your del.icio.us tags, links, and functions handy, or a single page where you can save the site you're browsing directly into your del.icio.us account, along with comments and chosen tags. This tutorial shows you how to use Ajax to build just such a page using a PHP script as the server-side proxy. |

Jump-start your PHP applications with the Eclipse PHP Class Generator plug-in
PHP classes can sometimes still be a black box, a big unknown to many new and
some old-school PHP developers. But it doesn't have to be that way. Classes help
modularize code and remove extraneous copies of code scattered throughout the code base
by placing the code into functions within classes. This helps make maintaining
your code much easier. That's what the PHP Class Generator plug-in for Eclipse helps
PHP developers do: generate PHP classes to help manage database tables, so you don't
have to, which helps speed up the learning curve. |

Execute business processes with Eclipse
Everyone -- from consultants and analysts to architects and engineers -- has
ideas. But implementing a new idea can be challenging, requiring knowledge of an
unfamiliar development language or hiring costly developers. What if there was a way to
create an executable business process using a graphical editor that can ultimately be
executed on an appropriate engine? Well, there is. Using the Eclipse STP BPMN Modeler,
you can graphically create a business model represented in XML that can be converted to
an executable using Eclipse ATL that will ultimately deploy on Apache ODE. |
