About this Course

Developing Rules Applications with Red Hat JBoss BRMS (JB463) teaches rule developers and Java™ enterprise application developers how to create, test, debug, and control business rules, how to generate rules packages, and how the Red Hat JBoss BRMS [business rules management system] runtime environment executes rules. Students will use Red Hat JBoss Developer Studio 7 and Red Hat JBoss BRMS 6 to perform detailed, hands-on exercises that enable them to create and manage business rules in a production environment. The principles in this course can be applied to implementing a standalone Red Hat JBoss BRMS solution or a Red Hat JBoss BPM Suite [business process management] solution.

Audience Profile

  • Rule authors responsible for authoring and testing rules, using Red Hat JBoss Developer Studio
  • Java application developers responsible for developing and integrating business rules into Java and Java EE enterprise applications

Course Content

During this course, students will be:

  • Authoring basic business rules in Red Hat JBoss Developer Studio
  • Authoring advanced rules
  • Testing and debugging business rules
  • Using spreadsheet decision tables
  • Authoring and using DSL mapping files
  • Red Hat JBoss BRMS architecture and runtime rule execution
  • Controlling rule execution and preventing conflicts
  • Complex event processing (CEP)


  • Basic Java and Java EE programming experience
  • Knowledge of the Eclipse IDE, Maven, and GIT are useful, but not essential
