The Internet’s a dangerous place for a message. Component failures, network connection issues, and other problems can prevent a message from being delivered. Fortunately, there’s WS-ReliableMessaging, which makes sure messages get through. This article explains how to use reliable messaging, why you should use it, and how to use it with WSO2’s Web Services Application Server (WSO2 WSAS) 2.1. What Is Reliable Messaging? Reliable messaging may seem like a dull thing. We’re used to being able to rely on the Internet, so why worry so much about increasing the reliability of something that’s already reliable.

Using Java's Exception System to Sing 99 Bottles of Beer

Mike Galpin's Blog First off, if you like programming, you should check out this hilarious site on the venerable song 99 Bottles of Beer. Ok, now I am assuming that you just spent the last hour or so at that website, but you are back. If you are into Java, one of the most interesting solutions is one that eschews typical control structures (for/while/do loops) and instead uses Java's exception system to sing the song. Actually the way that I came across the site was from an email sent by one of my colleagues. He was amused by the exception based solution. I was amused, too. Obviou... (more)
