I'm brand new to Pentaho and I'm trying to do the following workflow: read a bunch of lines out of a DB do some transformations POST them to a REST web service in JSON I've got the first two figured out using an input step and the Json Output step. However I have two problems doing the final step: 1) I can't get the JSON formatted how I want. It insists on doing {""=[{...}]} when I just want {...} . This isn't a big deal - I can work around this since I have control over the web service and I could relax the input requirements a bit. (Note: this page http://wiki.pentaho.com/display/EAI/JSON

I want to get all the table names from the database and then get all the rows from the tables. So I created a transformation like this: Get Table Names: Added the database connection and stored the table name in a output field called "tablename".

I have read up a lot of tutorials online, including the documentation . My problem is that everywhere it says that I my "?" should be replaced with the parameter. But this does not happen. Here are
