ALSB 3.0, response not transforming

Question

I'm trying to perform a simple XQuery transformation on the request and response for a service. I have created the single route, and for the request and response pipelines I have configured a Replace action that uses an XQuery to transform the $body and place it back into the $body. This works fine for the request action but the response action doesn't appear to be executing the transformation. I suspect I am not fully understand how the context variables $body works. Any points would be appreciated.

Answer 1

When you call a service route, the response will be in the variable $body. What I suspect you want to happen is you want to map the response body of the service route to the response of your service.
This can be confusing, so what I tend to do is have a step with a new assign. I have an XQuery that maps the response of the route sevice to the service response. I assign this to a variable. I then do a replace. I find it confusing doing a replace when both the variables are called body. These steps should be performed on the response pipeline.
Hope this makes sense.
cheers
