Web 2.0 Development with the Google Web Toolkit

The Google Web Toolkit allows for modern Web development using Java, without ever needing to write a single line of HTML or JavaScript.

There's much hype related to Web 2.0, and most people agree that software like Google Maps, Gmail and Flickr fall into that category. Wouldn't you like to develop similar programs allowing users to drag around maps or refresh their e-mail inboxes, all without ever needing to reload the screen?

Until recently, creating such highly interactive programs was, to say the least, difficult. Few development tools, little debugging help and browser incompatibilities all added up to a complex mix. Now, however, if you want to produce such cutting-edge applications, you can use modern software methodologies and tools, work with the high-level Java language, and forget about HTML, JavaScript and whether Firefox and Internet Explorer behave the same way. The Google Web Toolkit (GWT) makes it easy to do a better job and produce more modern Web 2.0 programs for your users.

What Is Web 2.0?

This question has several answers, including Sir Tim Berners-Lee's (the creator of the World Wide Web) view that it's just a reuse of components that were there already. It originally was coined by Tim O'Reilly, promoting “the Web as a platform”, with data as a driving force and technologies fostering innovation by assembling systems and sites that get information and features from distributed, different, independent developers and services.

This notion goes along with the idea of letting users run applications entirely through a browser, without installing anything on their machines. These new programs usually feature rich, user-friendly interfaces, akin to the ones you would get from an installed program, and they generally are achieved with AJAX (see the What Is AJAX? sidebar) to reduce download times and speed up display time.

Web 2.0 applications use the same infrastructure that developers are largely already familiar with: dynamic HTML, CSS and JavaScript. In addition, they often use XML or JSON for representing and communicating data between the server and browser. This data communication is often done using Web service requests via the DOM API XMLHttpRequest.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
