WCF send port behavior

I still had this drawing lying on my desk since 2009. As it MIGHT be almost correct, why not publish it? ;-)

RESTful Enterprise Development

Comments (2) | Share

This is a very slick REST based sample that leverages ATOM feeds to publish event notifications. Hats off to Ian and the guys behind the sample. Nothing can beat the good old polling consumer. With an ATOM implementation the guaranteed delivery responsibility is in the hands of the consumer. This opens up the possibility for the consumer to further ......

CharacterTranscoder pipeline component on github.com

Comments (2) | Share

CharacterTranscoder is a BizTalk pipeline component + stream class that can transcode a stream from a configurable source encoding to a configurable target encoding. The source is now available on github.com. Git takes some time to get used to. I managed to put something online somehow, which means everybody should be able to :-) Microsoft also offered ......

Question marks in your flatfile output CONTINUED

Comments (1) | Share

In order to get the FFASM encoding bug looked at, Microsoft Support asked me to call an 0800 number and provide payment info :-( Since I am still convinced every bug should be reported I will try again next month when I have my client's support contract details (the guy with the info is on a very long summer holiday :). In the mean time I have developed ......

Question marks in your flatfile output?

Comments (2) | Share

Or how to fix a bug while introducing another one that's a lot nastier. Let's start by describing the original bug: the BizTalk flatfile assembler has issues with custom target (output) encodings. When compiling a custom pipeline with the FF assembler and configuring the 'target charset' in the pipeline designer everything works as expected and you ......

BizTalk Arbitrary Binary Email Attachments (or how to fix unreadable attachments)

Comments (4) | Share

Recently we have been receiving another series of complaints from clients that had trouble reading the pdf attachment of a BizTalk dynamic generated email. For some years we have been using the MIME encoder pipeline component and dynamically buildup our emails as multi-part message from inside orchestration. We got the mustard from here. As said, it ......

BAM Typed API alternative

Comments | Share

The previous BAM portal post reminded me of some BAM classes I re-use but never blogged about... Here is my small-scale proven semi-automated alternative based on the mapper pattern and nullable fields. The core functionality comes from a 'BAM gateway class' which is composed with a IMapper<A,B> instance, responsible for mapping strongly typed ......

Configuring a Static WCF Port to Behave as a Dynamic Port

Yesterday I've tried to reproduce the scenario 'Configuring a Static Port to Behave as a Dynamic Port' from the excellent MSDN article 'Consuming and Hosting WCF Services with Custom Bindings in BizTalk Server' but with a twist: instead of writing the BTS.OutboundTransportLocation context property inside a custom pipeline component I've tried doing ......

Custom StreamReader with FSM

Comments | Share

This post is about Finite State Machines, the Flying Spaghetti Monster is for next time. For one of the EAI projects I'm working on I needed a specific StreamReader that adds field-wrappers (around the fields, obviously) of a char-based stream. For example: field1-1,field1-2;field2-1,... => "field1-1","field1-2";"fiel... My first ......

Some thoughts on Service Location (SL) and Dependency Injection (DI) with BizTalk...

Comments | Share

My motivation for this post comes from the fact that I could only find 1 blogpost related to BizTalk and DI: it was about DI using Spring.net and late binding, and it was in fact rather about SL. I'm not pretending to be an expert on the subject but a second blogpost with a little bit of background on the subject of dependency resolution in the context ......

About compatibility…

Comments (1) | Share

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 that for the BizTalk 2006 version the Microsoft BizTalk product team has: 1. Checked the re-used ......

BizTalk 2006 SDK: new BaseAdapter

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). Adapters that have been originally built with the 2004 adapter base classes should continue ......

BizTalk WMI programming: How to write cleaner WMI code a lot faster

Comments (17) | Share

I’ve seen numerous handy WMI scripts and code samples from fellow BizTalk bloggers and from the BizTalk help. Amazingly every one of these samples use late-bound objects calls to invoke methods and access properties from the BizTalk management objects. This makes the code rather verbose, it’s very inconvenient and also very error prone. ......

The BizTalk SQL Server Adapter isolation level

Comments (10) | Share

The isolation setting is fixed and is SERIALIZABLE. So beware that even your most basic receive locations that only execute those very simple SQL statements such as 'select * from tablename' can generate locks. BTW, this is a general misconception: usually people think that select-statements never lock resources. Nothing is less true of course. While ......

About publisher policy assembly chaining

Comments (4) | Share

I've just found out the hard way that GAC'ed publisher policy assemblies do not chain. When you have a policy.1.0, redirecting the binding of assembly v1.0.0.0 to assembly v1.1.0.0 and also having a policy.1.1, for redirecting the binding of assembly 1.1 to assembly 1.2, this doesn't result in a binding to the assembly 1.2 when your app requests 1.0 ......

The BizTalk Configuration Dilemma

I’ve watched several times Jurgen Willis’ excellent online presentation about the Business Rule Engine (BRE). One of the BRE usage scenarios demoed by him contains a sample orchestration that uses the BRE to dynamically configure a delay time. This confused me since it added another option to accomplish dynamic configuration of business processes. We ......

Executing pipelines from inside an orchestration: Introducing the LOOPBACK adapter

MSMQT Set up a schedule with 1 MSMQT send port and 1 MSMQT receive port sharing the same MSMQT queue name (for example ' loopback' would make a lot of sense) Create a correlation ......

Leveraging MSMQT acknowledgments

You all probably know that MSMQ stands for 'Microsoft Message Queuing' and MSMQT is the acronym for describing the BizTalk MSMQ adapter. A quick reminder for those who already forgot: the "T" in MSMQT stands for transactional (not “Transport”) Probably less common knowledge is what MSMQ acknowledgments (ACKs) are, so I have chosen this to be the topic ......
