I worked through a problem recently with a client that really took me by surprise - because I would think that many BizTalk shops would be running into this issue regularly. So! Here goes with an explanation and a solution. We ran into this problem initially...

Jesus Rodriguez has created a super cool adapter for BizTalk Server 2006 that talks to SQL Service Broker in SQL Server 2005 so that you can use SSB as a transport for SQL to SQL communications within a broader BizTalk Server ecosystem. His adapter is...

The BizTalk 2006 version and API is 100% backwards compatible with the 2004 version and API. BizTalk 2006 is built against .NET2.0 while the BizTalk 2004 assemblies were built against .NET1.1. Although I’m not working for Microsoft this surely means...

What do you do if you have over 1000 suspended orchestrations, each one would have put a message to the event log when it suspended, however the event log entry does not tell you which instance of the orchestration generated the message, given they could...

The SDK of BizTalk 2006 Beta2 will include a new version of the adapter base classes. These will not be backwards compatible with the original BizTalk 2004 SDK classes. The API has changed and the internals have changed (uses System.Transactions for example...

The Aggregator Service Orchestration Background Think of this implementation as a BizTalk orchestration imitating the functionality of a Windows Service i.e. you have the ability to start, interrupt and stop the orchestration, otherwise like a service...

Firstly I haven’t blogged for a while as I’ve been hard at work down in Wellington. Two of us implemented a credit card issuing and re-issuing integration app (5 partners) in just under six weeks. We were very impressed with the speed of developing...

The answer is no. Here is an excerpt from David Chappell's excellent whitepaper: Introducing Microsoft Windows Workflow Foundation: An Early Look Use Windows Workflow Foundation when: An application will itself host workflows. Windows Workflow Foundation...

Get Your Kicks with 2006… It’s been a busy summer, and in Sweden you have to make the most of it. But, eventually, here is the latest version of the guide. Big credit to Stephen Thomas and Matt Hall for keeping the good posts coming. There’s a whole bunch...

I mentioned before that I'll be doing a webcast on the Windows SharePoint Services native adapter included in BizTalk 2006 (see SeptemberWSSAdapterWebcast ). The "BTS 2006 Windows SharePoint Services (WSS) Adapter Deep Dive" webcast is now...

Dave Green has started his blog, welcome Dave!. Dave is the WWF Architect, and he's been having stacks of fun building out Microsoft's workflow platform, I have to say WWF looks really cool. Dave's a very smart cookie and has been building...

For those following the debate on the implementation of the Rete algorithm in the Microsoft Business Rules Engine, you may be aware that I undertook to port some CLIPS/Jess tests provided by Peter Lin to the MS-BRE and to publish the results. This follows...

When exploring different rule base vendors, you probably encounter references to the RETE algorithm by Charles Forgy. This algorithm has proven itself to scale well for very large ruleset. In all my years of experience, I've never encountered a client...

This documents helps you understand the key technologies from Microsoft and IBM in the integration space. It then compares and contrasts the various products and technologies. The goal of the document is to provide you with apples to apples comparisons...

I have had some fun in the last couple of weeks debating the Microsoft Rules Engine with Peter Lin . Many people in the BizTalk community will know that Peter used Amazon and The ServerSide site early this year to launch an attack on Microsoft's representation...

We had a bunch of fun recording this video for channel 9 on the BizTalk Server Solution Designer which is coming after BizTalk Server 2006 and was shown to folks at PDC along with a demo of Windows Workflow Foundation in an ASP.NET web-site talking to...

Windows Workflow Foundation has been officially announced at the PDC. Get a load of this, from Darren Jeffords blog; For those of you familiar with BizTalk Server 2004, Windows Workflow Foundation is analogous to the Orchestration Designer and Orchestration...
