BizTalk Server 2004 Generic Adapter SampleMicrosoft® BizTalk® 2004 enables connectivity to external systems through an extension API called the Adapter Framework. Adapters in BizTalk are the main carriers for messages (either into the BizTalk messaging repository, called the "message box" or out of it). Out of the box, BizTalk 2004 comes with adapters for open protocols such as file, http, soap, ftp and others. System-specific adapters for SAP and MQSeries are also available. The adapter framework, while being versatile and enabling extension point for writing adapters for everything you can think of, are non trivial to implement and require thorough understanding of the interface with the BizTalk runtime. This document describes a "generic adapter" (its code is accompanied), which serves as an abstraction layer and enables writing "custom adapters" quickly and easily.
BizTalk Server Adapter for SharePoint LibrariesThis article describes a Microsoft® BizTalk® Server adapter that facilitates end-to-end communication between front-end Microsoft Office System 2003 applications and back-end enterprise systems. SharePoint libraries store Office System XML data while BizTalk Server orchestration provides services for integrating that data with back-end systems. This adapter makes SharePoint libraries accessible to BizTalk Server 2004 to provide an end-to-end integration path from the Office System 2003 applications to back-end enterprise systems
BizTalk Server 2004 Beta – Request BrokerThe Request Broker scenario sample for Microsoft BizTalk Server 2004 Beta demonstrates how you can use BizTalk Server 2004 to implement a uniform request handler solution. The sample is intended to demonstrate development best practices to be used when building applications on BizTalk Server 2004. Annotated source code is included for review to help you understand how the application was archtected and built.
BizTalk Server 2004 Beta – Request for QuotationThe Request for Quotation for Biz Talk 2004 Beta demonstrates how you can use BizTalk Server 2004 to implement a RFQ solution. The sample is intended to demonstrate development best practices to be used when building applications on BizTalk Server 2004. Annotated source code is included for review to help you understand how the application was architected and built. Documentation is also provided which explains the scenario in detail including instructions for setting it up and running it.
BizTalk Server Fail Fast Tutorial and sample AICFail fast process is the process where Microsoft BizTalk Server 2002 shuts down an XLANG schedule instance even if it is not completed. In the fail fast process, the DTC transaction rolls back and the XLANG schedule shuts down without calling any On Failure or Compensate code. In highly sensible systems this can force the developer to create a tracking mechanism to make sure all instances completed, and re-try if not. To make this process easier, we replaced the Generic AIC with our own AIC which sends a Message Queuing message to a tracking queue and only then send it to the original private queue.

BizTalk Baby StepsBy Christoph Schittko
The lack of BizTalk developer documentation however, is making it very hard to take your first baby steps with BizTalk. You feel like a toddler with the urge to run, but you first have to master taking simple steps first. I had quite a few moments where I just wanted to plop on my butt an cry until my mommy comes and makes it all go away ... I hope this article will help some people to get past the baby step phase quicker and get them running in no time.
