Processing Data From an AJAX Request

In a few of my previous videos, I introduced you to several concepts on how to use AJAX for web development on the IBM i (System i, iSeries, AS/400). In this video, I discuss with Robert Ferguson, an IBM i web developer, what it takes to utilize the AJAX data that is returned from the server. Robert will provide an example by showing us how AJAX data can be displayed on a Web application’s screen with little effort.

How Web Application Development Evolved

In this video, I go over the evolution of Web application development. You will discover how it progressed from simple HTML-based documents into Rich Internet Applications, where the user interface controls the flow of the application and makes simple requests for data and business logic. In this paradigm, server-side code is not generating new HTML pages every step of the way; therefore, applications are more cohesive and maintaining application state becomes much easier. I also explain how Rich Internet Applications (RIAs) allows for a simple way to integrate your IBM i data and business logic with external systems, data, and applications.

Introduction to Rich Internet Applications for the IBM i

In this video, you will be introduced to Rich Internet Applications (RIAs) as they relate to the IBM i (AS/400, iSeries, System i). I will explain some of the details behind this technological phenomenon, and show you why it has top research companies making strong claims about its future in the market. You will see how RIAs compare with traditional Web applications, and how utilizing RIA Libraries and Frameworks can help you create powerful user interfaces (UIs) with little to no coding.

Sending AJAX Requests to the IBM i (iSeries / AS400) Server

To fully utilize AJAX on the System i (iSeries/AS400) system, you need to learn about 3 simple things:

  1. How to make requests from the browser to the server
  2. How to respond to these requests with RPG or another web-capable language
  3. How to process that response within the browser

In this video, I talk about making requests, which can be tricky. Unless… you utilize an AJAX library. With an AJAX library in place, it’s really simple to make server requests either directly from HTML code or from a Rich Internet Application platform.
