Changing BizTalk Mapper Item templates

 

To be able to configure default value for artifacts that are created from within Visual Studio we can leverage the ‘Item Template‘ functionality.

I have done this to adjust the mapping behavior , specifically the value for setting ‘GenerateDefaultFixedNodes’ which is default ‘YES’. See my previous post on this subject.

Below are the steps to follow

The ItemTemplates is a folder that contains the template files used when you create a new item.

clip_image001

The map template can be found in the folder: Map Files

This is a .zip file that contains a .BTM file. Change the value of ‘GenerateDefaultFixedNodes’ to one of the above values and save the .zip file.

clip_image002

After changing the value, the template is not working, why??? The templates are cached in the folder:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCached\BizTalk\Map Files

clip_image003

clip_image004

You have to register the value by entering the following command (devenv /installvstemplates):

clip_image005

Note: if you have multiple zips files, the FIRST zip file is used, i made the mistake to rename the original Map.old.zip, which still resulted in the old template to be registered.

If you create a new MAP, the template will now be used:

clip_image006

clip_image007

Note: The only supported values are: ‘Yes’ / ”” / ‘RequiredDefaults’, i recommend to use ‘RequiredDefaults’

Be sure to read this (Accommodating Schemas with Large Footprints)!

“when the GenerateDefaultFixedNodes flag is set to No, the default field values set in the target schema are not preserved in the instance produced by the map. This is a problem when these values are required in the target instance”.

UK Connected Systems User Group – BizTalk Services questions

This Wednesday I’m attending the CSUG – The Hybrid Organisation (sold out!). During my evaluation of several Integration products (BizTalk / BizTalk Services / Neuron ESB / MuleESB) I had some concerns/questions on BizTalk Services. My goal is to get answers on the following scenario a) I receive a HTTP Post with an Xml Body payload b) This contains a signature which i need to validate c) Transform the Xml body payload to another Xml message d) Perform a HTTP Post with the new Xml message to an external HTTP url and sign the message e) Route the response back, similar to the aforementioned steps, where an error needs to be mapped to a dedicated error response Challenges I'm wondering how to cope with some of the following challenges in this scenario, and would like to know resource information available which addresses some of these challenges; Validating / Signing of messages A requirement is to validate the incoming message by inspecting an signature in the message
