I have a client app that needs to do a transformation, then hit an orchestration where it calls a Rest service, make a request and return a response, then return the response back to the calling client, is this possible with BizTalk? I have the inital orchestration as a web service..
I have tried calling the web service from inside the Orchestration which I converted to a wcf web service with the BizTalk Wizard. It throws a multiple send error..
I used custom pipelines to call the REST Service to convert to JSON for the request, and convert to Xml for the response. Which works fine, its how to get the response back to the orchestration, then back to the client.
I started to look at ESB and it seems like its overkill for what I need to accomplish.
