Java Axis2 Client to .Net Web Service - XML Parsers Galore

The last time I did any significant Java was in 2001 when I wrote an object bridge to integrate Microsoft COM+ technology with CORBA objects. Back then I was purely a Java guy. It was a rather sweet feeling to be able to accomplish the task. I used the combination of VJ++, IDL2Java compiler and […]

ADO.Net DataSets, Web Services and Interoperability

Just the other day I overheard my friend Amigo having a little technical discussion with his colleagues. His colleagues hang together and sing on similar tunes in great harmony. Therefore, for the purpose of this post I will refer to them as a single entity: ‘peers’.  The subject of discussion was the same as the […]

Inheritance and XML Schemas

Often you need to employ OO patterns when solving integration problems using XML.
Inheritance is especially useful when you are looking to abstract commonality within a base type. Thus ensuring less redundant code and reuse…
The W3C XSD syntax allows you to create complex types (complexType), import schemas (import), refer to imported schemas using namespaces and inherit […]

Storm in a teacup

Through 2001 - 2004 timeframe, I used the Web Service Studio 1.0 and 2.0 from gotdotnet.com to great effect. It was the magic tool I needed to inspect/debug soap packets/web services without having to sniff network packets. I could hit breakpoints at will. It was like a dream come true.
While I was working on some […]

VOIP (PennyTel) - Incoming Calls - Problem

I have been using VOIP (PennyTel) now for nearly a year. Initially, this was only my outbound ISD solution. However, recently, upon changing my ISP and moving homes, I decided to pilot this as a primary telephone service for all needs:

PennyTel to local/interstate/international PSTN (outbound)
Local/interstate/international to PennyTel (incoming)

#1 was tried and tested, so I […]

Windows Communication Foundation (WCF) - Putting it All Together

 
After doing some basic Google searches, I realised that there weren’t enough samples out there that would demonstrate WCF how-does-it-hang-together conceptually. Therefore, I decided to put together one such sample.
Hardly production / best practices compliant, the aim of this article and adjoining sample is to familiarise readers with the key classes and semantics involved […]

Overriding Functions - JavaScript

 
I have been around in the sysdev scene for a fair bit. However, I have been able to very skillfully steer clear of this beast: JavaScript.
I could take my fair share of middle-tier, cross-platform integration, design patterns, and anything OO in just about any programming environment. However, ask me to write more than a couple of lines of JavaScript […]
