When you open up any Jetletter Page Builder folder there is a project .PJB file that is managed by the workflow manager where you can set options. Once options are set the way you like you can just double-click the .PJB file and Jetletter Page Builder runs exactly what you requested..
This option means that you can run any project from the command-line or from powershell as well. Setup as many options as you like and just rename each .PJB file with the options you want.
This is my favorite option and the most flexible way to run jobs hands-free!
I have even built SQL commands to execute powershell in the file-system to run projects where Jetletter Page-builder has ODBC connection to SQL. This is the dream! You can build a record set in SQL, then trigger your Jetletter Page Builder outputs from SQL-2-Powershell scripts hands-free and all ran from SQL Active Agent. I live for hands-free personalized VDP output on-demand.
We create 2 .pjb files. 1 for proofing and 1 for printing and trigger each on demand with windows powershell. easy, peazy!
