If I could pass just one Flex advice that would be: Use Data Transfer Objects. Use custom Data Transfer Objects to pass data between server and Flash tiers of your Flex application. Do not use XML. Yes, I know that XML cool. Do not use raw objects.

For security reasons (similar to the Java sandbox concept), Flash clients can only access the domains they come from, unless other servers declare, explicitly or implicitly, trust to SWF files downloaded from our domain by a corresponding record in a crossdomain.xml file. But our portf...

This excerpt describes the process of creating a complete Flex-Java distributed application. Upgrading Flex applications to Java Enterprise Edition applications is done with Flex Data Services. FDS provides transparent access to POJO, EJBs, and JMS and comes with adapters for framework...
What I love about Adobe Flex is that it is a framework in addition to a pretty impressive library of off-the-shelf controls, which can fit the bill for many of the Rich Internet Applications. Flex enables you to create new and extend existing components with a simplicity and elegance h...

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. In any UI framework, the robustness of such a component depends on format...
Flex framework contains a pretty impressive library of the off-the-shelf controls, which can fit the bill for many of the Rich Internet Applications needs. And yet, it is just the tip of the iceberg, because Flex enables you to create, combine and/or extend existing components with a s...

In Part 1 (CFDJ, Vol. 8, issue 10) we introduced the destination-aware grid, formatters, and renderers. In this article we are continuing our discussion about datagrid renderers and...

In this excerpt from our book, Rich Internet Applications, we'll cover how to set up large applications intended for Web or, more broadly speaking, distributed deployment. As an example let's consider an enterprise application that consists of hundreds of screens, reports, forms, and d...

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 ac...

The simplest way to explain Flex Data Services (FDS) is to compare them with Flex Remoting. Simply put, FDS addresses only a subset of operations facilitated via Flex Remoting - result set requests. However, whereas Flex Remoting enables one-way requests, FDS combines one-way requests ...

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 inte...

A typical Java developer knows that when you need to develop a GUI for a Java application, Swing is the tool. Eclipse SWT also has a number of followers, but the majority of people use Java Swing. For the past 10 years, it was a given that Swing development wouldn't be easy; you have t...

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 t...
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#...

In Part 1 of this article (PBDJ, Vol. 8, issue 12) we presented the technology for building and using HyperTextObjects (HTOs). HTOs enable authoring of powerful HTML/JavaScript controls that can easily mimic the functionality and APIs of PowerBuilder controls.
Let's face it: we would love to put our PowerBuilder systems on the Web. As the industry trend is to make every new project 'Web-enabled,' our PB applications have already acquired the word 'legacy' in front of them.
IT projects closely follow the path of technology. .For example, the number of Java/XML/HTML projects is increasing, replacing PowerBuilder or VisualBasic systems developed just a few years ago. And developers are asking themselves the question: Do I have to write the same app from scr...
The ability to deploy applications on the Internet or intranet has become essential for application development, especially when developing new applications with Internet/J2EE-compatible tools. For PB developers this meant that instead of a single high-level integrated environment, th...
