BizTalk, RabbitMQ and JSON

In recent weeks, I happened to integrate RabbitMQ with BizTalk Server 2013. Great, I thought, there is a magnificent TechNet article that explains how to do it.

Too bad that I had to communicate using Json.

Anyway, Eventually I succeeded, but with some customization that I want to share.

The step to follow are four:

1. Follow the article http://social.technet.microsoft.com/wiki/contents/articles/7401.biztalk-and-rabbitmq.aspx to configure all the components

2. Customize RabbitMQ .Net Client

3. Follow the article https://pellitterisbiztalkblog.wordpress.com/2014/05/05/send-and-receive-json-formatted-message-with-biztalk-server/ to Implement a custom pipeline component to receive e send Json messages

4. Configure the send and receive ports

To customize RabbitMQ .Net Client

Open the solution and modify “rabbitmq-dotnet-client-3.2.1\projects\wcf\RabbitMQ.ServiceModel\src\serviceModel\RabbitMQInputChannel.cs” file.

In particular, find the “Receive” method and change the following highlighted line of code:

With the following:

var ms = new MemoryStream(msg.Body);

var bodyString = Encoding.UTF8.GetString(ms.ToArray());

System.Diagnostics.Debug.Write(bodyString);

bodyString = String.Concat(@”<s:Envelope xmlns:s=””http://www.w3.org/2003/05/soap-envelope”” xmlns:a=””http://www.w3.org/2005/08/addressing””><s:Header><a:MessageID>urn:”, Guid.NewGuid().ToString(), “</a:MessageID></s:Header><s:Body>”, System.Web.HttpUtility.HtmlEncode(bodyString), “</s:Body></s:Envelope>”);
