I made some progress by following the Scenario 2 on the link in my previous post.
I've configured my job as shown in the attached screenshots. I independently created a map in the Data Mapping perspective. Then I switched to the Integration perspective, created the job as shown and mapped to the map I had created in the Mapping perspective. Unfortunately, it failed with the following error:
Starting job Test004XML at 17:15 17/04/2014.

Overall: Fatal

2: Fatal - The transformation engine failed. (202)
