How to get Oracle Drivers to work on an x64 Box for SSIS
Just a couple of weeks ago, I was tearing my hair out trying to meet a really tight timeline and at the same time trying to solve a technical issue which in my opinion is a total waste of time. If anyone of you had ever tried to make SSIS and Oracle work on a 64 bit machine, I am sure you know what I was referring to. Fortunately we have people like Steve McHugh and Greg Galloway, who both wrote some excellent how-to articles addressing this issue. I've now grown so dependent on these articles (especially ......

How do you invoke a Workflow from WCF Service?
It took me a while to come to this blog post from Bart. He wrote a very simple and easy to understand article on how you can invoke a workflow engine from a IIS / Self Hosted WCF service. This is very useful from the layered architecture perspective since most service-oriented systems will not have the presentation layer calling the workflow engine directly. More often than not (depending on the complexity of the system), you will want to inject a communication service layer in the middle to handle ......

Quick guide in accessing WCF Service via Web Application
I was writing a proof of concept which uses WCF, WF and ASP.Net 2.0 and across some problems when I tried to call a WCF service from the web application client. Turned out that I spent an hour wasted trying to debug my application because I did not place the proxy.cs file into the App_Code of the web application. I had it documented down and wrote a simple and straight forward tutorial on how you can use a web application to access and call a WCF Service. The article is uploaded into the article ......

That annoying "Could not find endpoint element with name..." error
While developing WCF client/services, I frequently encounter this annoying error whenever I run my client to connect to the service contract for the first time. I term them as "timewasters". This post will partly serve as a reminder to me, and hopefully someone will benefit from it if they came across the same problem. The story goes like this, you start up your usual Visual Studio 2005 to work on a simple WCF's application (you know the usual service <-> client stuffs). So you created your ......

SOA Demonstration
This is old news, but Brain Groth and Mark Berman released a demonstration of what I'll call a true-blue SOA hosted on Channel9.

Integrations with AS400s, SAP and some other systems4. SQL Server, Unix, J2EE Websphere, Speech Server and many systems which are unlikely to work together.5. Business processes driving systems ......

Some differences between Indigo and WCF
There're some difference between Indigo and WCF which I'll highlight here. 1. WsProfileBinding is not longer therewsProfileBinding is a secure, reliable and interoperable binding based on WS-Reliable Messsaging and used for one-way service contracts. Basically it's fire and forget. The current downloadable WCF installation no longer uses wsProfileBinding, instead you should use wsHttpBinding to replace that and use Reliable Session to configure that in the config file to enable reliable messanging ......
