jBPM (Java Business Process Management) is a powerful open-source workflow and business process management platform written in Java. It allows you to model, execute, and monitor business processes, making it a valuable tool for developing and automating business applications. In this tutorial, we’ll cover the basics of jBPM integration with Java step by step.


Before getting started, ensure you have the following:

  • Java Development Kit (JDK) installed on your machine (version 8 or higher recommended).
  • Apache Maven installed (for managing dependencies).
  • Basic understanding of Java programming language.

Step 1: Setting Up Your Project

  1. Open your Java IDE.
  2. Create a new Maven project.
  3. Add jBPM dependencies to your pom.xml file.

Step 2: Creating a jBPM Process

In this step, we’ll create a simple jBPM process definition using BPMN 2.0.

  1. Create a new BPMN file (e.g., sample.bpmn) in the src/main/resources directory of your project.
  2. Define your business process using BPMN 2.0 notation. For example, a simple process that prints “Hello, jBPM!” can be defined as follows:
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns=""
             xsi:schemaLocation=" BPMN20.xsd"
             exporter="Camunda Modeler"
  <process id="Process_1" isExecutable="true">
    <startEvent id="StartEvent_1"/>
    <sequenceFlow id="Flow_1" sourceRef="StartEvent_1" targetRef="ScriptTask_1"/>
    <scriptTask id="ScriptTask_1" name="HelloTask">
      <script>System.out.println("Hello, jBPM!");</script>
    <sequenceFlow id="Flow_2" sourceRef="ScriptTask_1" targetRef="EndEvent_1"/>
    <endEvent id="EndEvent_1"/>

Step 3: Running the jBPM Process

Now, we’ll write Java code to deploy and execute the jBPM process.

  1. Create a new Java class (e.g., JBPMExample) in your project.
  2. Write code to create a KieSession, load the BPMN file, start the process, and execute it.
import org.kie.api.KieServices;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession;

public class JBPMExample {

    public static void main(String[] args) {
        // Create KieServices instance
        KieServices kieServices = KieServices.Factory.get();

        // Load the process definition
        KieContainer kieContainer = kieServices.getKieClasspathContainer();
        KieSession kieSession = kieContainer.newKieSession();

        // Start the process

        // Dispose the session

Step 4: Building and Running the Application

  1. Build your project using Maven.
  2. Run the JBPMExample class.

You should see “Hello, jBPM!” printed on the console, indicating that the jBPM process has been executed successfully.
