Adobe has released the free, open source Flex SDK framework to enable developers to create Rich Internet Applications (RIAs). The Flex framework provides you with a method of creating cross-browser, cross-platform Web applications that is quick and simple. Flex applications run in the Flash player, which is installed on the majority of Internet-connected computers, but Flex provides you with an object-oriented user interface framework similar to Java's Swing. In this tutorial, develop a Facebook application in Adobe Flex that displays a slideshow of a user's Facebook photo albums. The Facebook application will contain a Profile box listing all of the user's photo albums, each a link to a Flex slideshow of that album. The Flex application will use the Facebook REST API to fetch the photos of the selected Facebook album and dynamically generate the slideshow.

A disconnect between the stakeholders who define requirements and the developers who implement them has long plagued software development. In recent years, frameworks based on dynamic languages and domain-specific languages (DSLs) have tried to bridge the stakeholder-developer gap by making code read more like normal language. This tutorial shows how easyb -- which provides a more natural DSL that is closely attuned to stakeholders -- helps developers and stakeholders collaborate effectively.

Learn how to debug Asynchronous JavaScript + XML (Ajax) Web applications using Eclipse, Aptana's iPhone Development plug-in, Aptana's Firefox JavaScript debugger, and Firebug.

Learn how to build a simple dynamic Web site using Rational Business Developer Extension and Enterprise Generation Language (EGL). The site you build has two pages: one to display a list of records in a database and another to allow users to change the data in one of those records. You can create this Java technology-based Web site without knowing any Java code or J2EE; this tutorial demonstrates Rational Business Developer Extension's ability to create complex applications using a simple business-oriented language and powerful graphical editing tools.

Get an overview of WebSphere Portal by following these two practical exercises in this tutorial. You'll also find demos that take you through the steps. You will develop and test your first portlet using Rational Application Developer with the WebSphere Portal Test Environment. Then, you'll deploy your portlet in a production environment using WebSphere Portal.

This tutorial is part of a continuing series designed to teach you how to develop rich Web applications using ThinWire and Java programming. In Part 3, you'll use ThinWire styling support to create dynamic, configurable style for any component at both global and component levels.

Explore mashup concepts and build a simple mashup. This series chronicles the creation of the ultimate mashup, an application that not only stores data from different mashups but uses semantic technology to enable users to create their own mashups by swapping services, or even by picking and choosing data. It uses Java programming and a combination of servlets, JSP, software from the open source Jena project, and DB2's new native XML capabilities.

Manage a mashup data cache. Improve performance with pure XML and a DB2 database. ou solve some of that problem by using DB2's new pureXML capabilities to build an XML cache, which saves the results of previous requests and also enables you to retrieve specific information.

Build and interpret Resource Description Framework (RDF) and RDF Schema Language (RDFs). Before you can tackle OWL, you want to be familiar with its base language, the Resource Description Framework (RDF) and RDF Schema Language (RDFs). This tutorial gives you a good background in both RDF and RDFs so you'll be ready to build ontologies for your Web services, and also able to make use of RDF's power with other projects as well.

Automatically choose between services and parts of service with the XML-based Web Ontology Language (OWL). Now that you know how to represent information in RDF, you can start to create an ontology using the XML-based Web Ontology Language (OWL), which will enable you to automatically choose between services and parts of services.

Give mashup users a choice of services in your application. Now that you know how to create an ontology that defines the concepts represented by a service, you can enable users to choose which service they want to use. You will take the ontologies created in Part 4 and use them to enable users to change out information sources.

This is the final tutorial in a series that shows you how to create a mashup application. At this point you have a working application and the framework in place so that the system can use semantic reasoning to understand the services at its disposal. In this tutorial, you will give the user control to choose a type of service, the data to pull from the Web service, and the presentation of that data.

The Spring Framework was built on the principle that Java EE should be easier to use, and in this six-part tutorial series we cover the complete Spring Framework, front to back, including how to implement its functionality with Apache Geronimo. This installment, Part 1 of the series, introduces you to the Spring Framework architecture and explores the instersection between Geronimo and Spring.

In this second installment, you'll develop, configure, and deploy your first application based on the Spring Framework. You'll also see how easy Geronimo is to install and how its Web Console simplifies deploying and managing Web applications.

In this in-depth introductory tutorial by Web application developer Igor Kusakov, you learn the basics of developing HTML widgets using Dojo; including how to refer an image, how to add an event handler to an HTML page, and how to handle composite widgets. Also, discover some important differences between plain old JavaScript-style coding versus using Dojo, and get tips for handling complex issues inherent in Web application development.

Discover three Ajax data transport mechanisms (XML Http, script tags, and frames or iframes) and their relative strengths and weaknesses. This tutorial provides code for both the server side and the client side and explains it in detail to provide the techniques you need to put efficient Ajax controls anywhere you need them.

This tutorial shows how to streamline Common Base Event logging instrumentation in Java.. You'll learn techniques and best practices that reduce maintenance requirements and let you increase customized, vendor-specific content.

Get an overview of the application, how it will work, and why using OASIS agreed Web services will make the development, deployment, and expansion of the system easier.

Build the framework for your movie grid app by defining your grid operations in Web Services Description Language (WSDL). You'll use that WSDL to build the code for the rest of the application, then add security using the WS-Security standard.
