Mastering JBoss Drools 6

By: Mariano De Maio, Mauricio Salatino, Esteban Aliverti

Overview of this book

Mastering JBoss Drools 6 will provide you with the knowledge to develop applications involving complex scenarios. You will learn how to use KIE modules to create and execute Business Rules, and how the PHREAK algorithm internally works to drive the Rule Engine decisions. This book will also cover the relationship between Drools and jBPM, which allows you to enrich your applications by using Business Processes. You will be briefly introduced to the concept of complex event processing (Drools CEP) where you will learn how to aggregate and correlate your data based on temporal conditions. You will also learn how to define rules using domain-specific languages, such as spreadsheets, database entries, PMML, and more. Towards the end, this book will take you through the integration of Drools with the Spring and Camel frameworks for more complex applications.

Creating our first Drools project


As mentioned in the previous section, we will use Maven to provide us with the project structure. For this, Maven provides the concept of archetypes, which are project templates that we can use to bootstrap our projects. Most of the IDEs provide a way to use these archetypes in order to create and initialize our projects. Check for your IDE if you need to download a Maven plugin or if Maven support is already bundled. If you want to do this via the command line, we can run the following command:

mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes 
  -DgroupId=org.drools.devguide
  -DartifactId=myfirst-drools-project

I recommend you to run this command in the drools6-dev-guide/chapter-02/ directory. This will enable Maven to inherit all the configuration from the parent project configuration defined in drools6-dev-guide/pom.xml. If you do this, your project will know the version of Drools that all the other examples in the book are using...
