Copy link

Red Hat build of OptaPlanner includes several examples that demonstrate a variety of planning use cases. Download and use the examples to explore different types of planning solutions.

Prerequisites

Procedure

  1. To run the examples, in the rhdm-7.11.0-planner-engine/examples directory enter one of the following commands:

    Linux or Mac: 

    $ ./runExamples.sh

    Windows: 

    $ runExamples.bat

    The OptaPlanner Examples window opens.

  2. Select an example to run that example.
Note

Red Hat build of OptaPlanner has no GUI dependencies. It runs just as well on a server or a mobile JVM as it does on the desktop.

If you use an integrated development environment (IDE), such as IntelliJ, Eclipse, or Netbeans, you can run your downloaded OptaPlanner examples within your development environment.

Prerequisites

Procedure

  1. Open the OptaPlanner examples as a new project:

    1. For IntelliJ or Netbeans, open examples/sources/pom.xml as the new project. The Maven integration guides you through the rest of the installation. Skip the rest of the steps in this procedure.
    2. For Eclipse, open a new project for the /examples/binaries directory, located under the rhdm-7.11.0-planner-engine directory.
  2. Add all the JAR files that are in the binaries directory to the classpath, except for the examples/binaries/optaplanner-examples-7.52.0.Final-redhat-00007.jar file.
  3. Add the Java source directory src/main/java and the Java resources directory src/main/resources, located under the rhdm-7.11.0-planner-engine/examples/sources/ directory.

  4. Create a run configuration:

    • Main class: org.optaplanner.examples.app.OptaPlannerExamplesApp
    • VM parameters (optional): -Xmx512M -server -Dorg.optaplanner.examples.dataDir=examples/sources/data
    • Working directory: examples/sources
  5. Run the run configuration.
