A Basic BRMS example

What is it?

This project demonstrates how to use BRMS to manage and deploy modules that contain model classes and rules.

  • The HelloWorldBRMSTest class creates 3 Sales object instances: vipSale, regularSale, and badSale.
  • These Sales objects are passed to the StatelessKieSession class, which runs the rules against them to verify and apply discounts.

Note: The Sale, Customer and CustomerType classes are defined on the following dependency: org.jboss.quickstarts.brms:helloworld-brms-kmodule:1.0.0. This dependency is a BRMS Kmodule that contains the model classes and the rules that were previously built. It is available on the the git repository:

The Maven dependency is available at the following Maven Repository: http://localhost:8080/business-central/maven2/

This quickstart does not contain a user interface layer.

System requirements

All you need to build this project is Java 6.0 (Java SDK 1.6) or later, Maven 3.0 or later.

The application this project produces is designed to be run on BRMS 6

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start the JBoss Server

If you have not yet done so, you must Configure BRMS before testing the quickstart.

  1. Open a command line and navigate to the root of the BRMS directory.
  2. The following shows the command line to start the server:

     For Linux:   EAP_HOME/bin/
     For Windows: EAP_HOME\bin\standalone.bat

Import the BRMS Repository

If you have not yet done so, you must Import the BRMS repository before testing the quickstart.

Deploy BRMS kmodule

  1. Start the JBoss Server as instructed above.

  2. Open a browser and access the following URL: http://localhost:8080/business-central

  3. Log in with the following credentials:

     Username:  quickstartUser
     Password:  quickstartPwd1!
  4. Choose menu option Authoring -> Project Authoring

  5. Choose the following options under Project Explorer:

     Organizational Unit:  example
     Repository Name:      jboss-brms-repository
     BRMS Kmodule:         helloworld-brms-kmodule
  6. Next, click on Tools and Project Editor

  7. In the tab on the right, click on Build & Deploy.

    • It will prompt you with a message: "Also save possible changes to project?". Click Yes.
    • You are prompted for a comment. Add a comment and click on Save button.

This deploys the org.jboss.quickstarts.brms:helloworld-brms-kmodule:1.0.0 artifact to the BRMS Maven repository. You can verify the deployment choosing menu option Deployment –> Artifact Repository.

Run the Tests

  1. Open a command prompt and navigate to the root directory of this quickstart.
  2. Type the following command to run the test goal with the following profile activated:

     mvn clean test -Penable-test

    The tests fail with compilation errors because the project does not have the necessary dependencies.

  3. Now run the following command to run the test goal with the following profiles activated:

     mvn clean test -Penable-test,brms

The brms profile enables the http://localhost:8080/business-central/maven2/ repository and adds the org.jboss.quickstarts.brms:helloworld-brms-kmodule:1.0.0 as a project dependency.

Now the tests complete successfully.

Investigate the Console Output

When you run the tests, JUnit will present you test report summary:

Test the Quickstart in JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

    mvn dependency:sources
    mvn dependency:resolve -Dclassifier=javadoc
