Browser-based applications are widely used and we like the fact that we can access them from anywhere. But from the users' perspective, the productivity level of Web applications still doesn't approximate the productivity of desktop programs. The good news is the gap is closing: the accumulated potential of multiple technologies has boosted a whole new breed of HTML-based apps that are as powerful as the desktop ones. Meet AJAX. What Is AJAX? The name stands for Asynchronous JavaScript + XMLHTTPRequest and means you can establish socket communication between browser-based JavaScript and the server. AJAX isn't a new technology. It's a successful branding of possibilities implanted in several technologies available in modern browsers. All AJAX applications deliver a rich UI via extensive JavaScript manipulation of the HTML Document Object Model based on the precision-p... (more)

Adobe Flex 2: Advanced DataGrid

In any GUI tool, one of the most popular components is the one that shows data in a table format like JTable in Java or Datawindow in PowerBuilder. The Adobe Flex 2 version of such a component is called DataGrid.

Web Enablement of DataWindows

Let's face it - rewriting an existing application from platform to platform is not fun. But many businesses successfully served with PowerBuilder applications are rewriting parts of PB apps for the Web and maintaining the same functionality in PowerBuilder and Java, PowerBuilder and C#, etc. Faced with this problem we decided to create a product called "XML Server Pages" that uses our DW2Java/DW2Net converters to automatically convert existing DataWindows into sets of J2EE or .NET objects - ready to run on the Web. For reporting applications of any complexity, including heavy fina... (more)

Developing Intelligent Web Applications With AJAX (Part 2)

The publicity that AJAX grabbed over the last half a year is based on closing the gap between the Web applications and the desktop applications, combining the "reach" and "rich." At the same time, the gap between the technological level of AJAX and what corporate developers expect in their modern arsenal is really astonishing. After all, AJAX is neither a tool nor a platform. There is no AJAX standards committee or community process in place. While software vendors are crafting proprietary development platforms on top of AJAX (which pretty much means "from scratch"), early adopte... (more)

SOA and RIA Together: Developing with Adobe Flex and Java

Rich Internet Applications are perfect for consuming enterprise services. As SOA evolves toward reusable components that can be accessed inside and outside of the corporate intranets, they need to provide outside developers with customizable pre-built components that can be easily integrated in composite applications. Adobe's Flex/Flash platform offers unique opportunities in both richness of the environment and global deployment accessibility. In this session we will uncover all the layers of successful SOA integration for RIA applications - including communication, customizatio... (more)
