This error is typically harmless, but can result when the XML Disassembler encounters an empty Envelope message instance that’s formatted like this:
instead of this:
BizTalk chooses to make a semantic difference between these two instances, and process the second one fine (publishing no messages), but raising an exception like this for the first:
There was a failure executing the response(receive) pipeline: “…” Source: “XML disassembler” Send Port: “…” URI: “…” Reason: Unexpected event (“eos”) in state “processing_header”.
This can happen particularly when using an XmlProcedure or XmlPolling from SQL – if the resultset is empty, the adapter will publish this message. While this behavior may be desirable (and can frequently be avoided by ensuring you have good Data Available statements on your polling ports, and only call XmlProcedures with valid parameters/at valid times), it can also generate a lot of alarming errors….
Dell Boomi’s AtomSphere integration platform provides a simple, yet very powerful feature – the ability to utilize temporary, and semi-temporary files system folders. Coming from a Microsoft BizTalk integration background, the ability to store documents to a temporary directory is a huge advantage over storing into a database such as the BizTalk MessageBox, especially with larger files. While BizTalk does provide the necessary mechanism to save files to a local folder through the use of the file adapter, Boomi provides an easier way of achieving this.
All of us who have worked on EDI integration know the pain of maintaining the integrity of the EDI messages coming into the system, as well as the value of validating them right from the pipeline-gate. To aid in this, Microsoft BizTalk Server supports out of the box verification of structural integrity with extended schema validation settings. The great part about this is that it allows us to reject any incoming EDI transactions right out of the gate and return those results in the generated ACK file. This way, we ensure that we don’t let invalid data into the system, while also making the sender aware of our “bad data” rejection.
However, as great as this feature is, it still leaves a major validation pain point.
Let’s consider following scenario.
Let’s say in the case of EDI 837 transactions, we consider REF*D9 as…
Typed Polling with WCF Adapters
It is very common to have a requirement in middleware design where we have to query SQL tables and retrieve some data when certein conditions are met.
The WCF-based adapters available with the BizTalk Adapter Pack enable the adapter clients to receive data-change messages from the SQL Server database(s). The adapter(s) support receiving “polling-based” messages wherein the adapter executes a specified SQL statement (SELECT statement or stored procedure), retrieves or updates the data, and provides the result to the adapter client at regular intervals of time. The adapters supports three types of polling:
Weakly-typed Polling (also called Polling),
Strongly-typed Polling (also called TypedPolling)
Xml-Polling polling using statements or procedures that include a FOR XML clause
For more information about the different types of polling, see Polling SQL Server by Using the SQL Adapter with BizTalk Server (http://go.microsoft.com/fwlink/?LinkId=221195).

A quick tip today – I came across an error while trying to enlist one of my send ports while deploying a BizTalk application using the amazing BizTalk Deployment Framework.
“Could not enlist Send Port ‘X’. Exception from HRESULT: 0xC00CE557 (Microsoft.BizTalk.SnapIn.Framework)
Recently I worked with a client to implement a solution to import data from an Excel file to SQL Server database. In order to provide a seamless user experience, we created a web page to allow user to upload file to server, then use BizTalk server to convert Excel file to XML file and call a web service to upload data into the SQL Server database.
By leveraging BizTalk server, we built a highly scalable and available data processing system for my client. Since my goal in this post is to introduce some core tools in the BizTalk, I simplify the real issue by 1) Changing the Excel file to the flat file, 2) uploaded data is saved into a file instead of database.
After completing this tutorial, you will be able to create flat file schema, convert flat file to XML…
