Aletyx Enterprise Build of jBPM¶

What is jBPM?¶

jBPM is a part of the Apache KIE (Incubating) delivering flexible Business Process Management (BPM) that enables organizations to model, execute, and monitor business processes throughout their lifecycle. As part of the Aletyx Enterprise Build of Kogito and Drools, our enhanced jBPM implementation provides a robust foundation for workflow automation with enterprise-grade extensions.

Key Components¶

Process Engine¶

At the core of jBPM is a lightweight, highly extensible process engine that supports:

BPMN™ 2.0 standard for process definition
Java-based execution environment for high performance
Persistence and transaction management for reliability
Asynchronous execution for long-running processes

Our enhanced engine includes optimizations for:

High-throughput process execution
Cluster-aware coordination

Runtime Manager¶

The Runtime Manager provides infrastructure for process instances:

Process instance lifecycle management
Runtime strategy selection (singleton, per request, per process instance) <!-- Is this still true - for KS, yes!>
Deployment unit handling for versioned deployments
Custom context propagation

Task Service¶

Human interaction is managed through the dedicated Task Service:

User task assignment and notification
Task lifecycle management
Deadlines and escalations
Form rendering and submission

Job Executor for asynchronous and scheduled work
Data Indexing Service for efficient querying
Process Audit Service for compliance and monitoring
Case Management for dynamic, adaptive processes →

Process Development¶

Process Definition¶

jBPM uses BPMN 2.0 for process definition:

<!-- BPMN HERE -->

The Aletyx Enterprise Build of Kogito and Drools provides:

Visual BPMN editors with validation
Process templates for common deployment and integration patterns

Java Development Integration¶

Process applications can be developed using Java APIs:

// Create a process definition
BpmnProcess process = BpmnProcess.from(new ClassPathResource("onboarding.bpmn2"));

// Configure and start the process engine
ProcessEngineBuilder.get()
    .register(process)
    .eventListeners(new ProcessAuditEventListener())
    .start();

// Start a process instance
ProcessInstance<Onboarding> instance = process
    .createInstance(new Onboarding("John Doe"))
    .start();

Deployment Models¶

jBPM supports multiple deployment scenarios:

Embedded within Java applications
Standalone process services
Containerized microservices
Kubernetes®-native deployments

Integration Points¶

jBPM integrates with:

Drools for decision-driven processes
Kogito for cloud-native process orchestration
Aletyx Studio for visual development
Spring Boot™
Quarkus™ for cloud-native applications
Enterprise messaging systems like Apache Kafka™, JMS
External services via REST, SOAP, or custom connectors
