When you create business rules of DRL format from Talend Studio, the created file is a DRL rule template that partially conforms to the Drools syntax. For more information on how to create the business rules, see the Creating the DRL rule template procedure.
To use a DRL rule template in your Job, select. When the Job is running, a file that conforms to the Drools syntax is generated from the template. This file is used in the Job.
In Built-in mode, the file you browse must conform to the Drools syntax. You cannot browse the Studio repository folders to select a DRL rule template.
If you switch the Property Type setting from Repository to Built-in, adapt the DRL file to the Drools syntax.
