How to import rules into Drools Guvnor from an xml file
Before you begin
About this task
Talend Administration Center incorporates the Drools Guvnor web application which enables business experts to easily and quickly build and change complex business rules directly via this Guvnor interface.
Drools Guvnor is a BRMS (Business Rule Management System) used to define, deploy, execute, monitor and maintain the variety and complexity of business rules. For detailed Drools documentation, see http://www.jboss.org/drools/documentation.html.
Drools Guvnor incorporated within Talend Administration Center allows you to use graphical editors to create and edit business rules.
An alternative is to import rules from an existing xml file. Once the rules are imported, you can still customize or test them, and apply them to data flows in Talend Jobs.
The following introduces how to import rules defined in an xml file into Drools Guvnor in Talend Administration Center.
