You need to sort your missing Jar issue. Just click on the Jar icon and search your machine for that Jar. If you cannot find a version of it, then just download it.

However you do not need to do it this way. The reason you are getting nothing is because nothing is being sent from your database component. You might have the column in your SQL but there is no column in the schema for it. In your DB component, go to the "Component" tab and click on the ellipsis button next to "Edit Schema". This will bring up the schema that you DB component is using. You need to add your new column there. It should then ask if you want to propagate your schema (although since you've already created it in you tMap, it may not). Every component (well, most) has a schema that must be set. The SQL query and the schema are not the same thing here.
