I went to Devoxx last week to present “iBeans – dead simple integration for the web”. Since the slides are pretty readable I figured I’d post them here for folks that missed it. I jotted down the questions and answers from the session below.
This screen cast takes you through all the steps necessary to download and set up iBeans, Tomcat and Eclipse. Then there is a walk-through of how to create a simple echo example (using AJAX) and test/debug the application on Tomcat. Yes, this is 11 minutes but it does walk through all the steps and provides a lot of additional detail. Grab yourself a beverage and take the the tour!
I just finished an iBeans screen cast that provides an overview of iBeans and provides a detailed tour of one of the examples that ships with the latest distribution. The example demonstrates how to schedule a task and perform bi-directional AJAX communication with the browser to plot geo-coordinates onto a map. This is the first in a series of screen casts for iBeans, the next one will demonstrate how to create an iBeans project in Eclipse.
My article on creating an SOA strategy in this tough climate was just published on eWeek:
The current economic crisis and recession is affecting both IT spending today and budgets for 2009. Often viewed as a major cost center, IT becomes one of the first areas where senior management looks to make cuts when times are tight. Here, Knowledge Center contributor Ross Mason explains how to build a recession-proof, service-oriented architecture strategy.
Defining what constitutes a service when building service-orientated applications seems to be a common problem for developers and architects who are new to building services. The main issue seems to be the scope, i.e. what is the granularity of the service. This is actually quite difficult since the granularity of a service can vary depending on the application. The trick with any fuzzy problem is to break it into smaller pieces. There is a very simple service taxonomy defined in Thomas Erls SOA in Principals of Service Design book which I believe makes the approach to defining services much easier.
