JBPM — Lesson 1: BPM and jBPM Architecture, BPMN Modeling, Events, Gateways, and Subprocesses

Learning Objectives

• Interpret the architecture, dependencies, and expected behavior of BPM concepts, jBPM architecture, and BPMN modeling.
• Apply events and gateways and subprocesses while preserving reviewable technical evidence.
• Recognize and correct the risk where a hidden prerequisite causes the first configuration step to produce an incomplete result.

Detailed Topics

• BPM concepts: apply the concept to a development team automating an approval and case-management process with jBPM, record the relevant settings or decisions, and explain the operational consequence.
• jBPM architecture: apply the concept to a development team automating an approval and case-management process with jBPM, record the relevant settings or decisions, and explain the operational consequence.
• BPMN modeling: apply the concept to a development team automating an approval and case-management process with jBPM, record the relevant settings or decisions, and explain the operational consequence.
• events and gateways: apply the concept to a development team automating an approval and case-management process with jBPM, record the relevant settings or decisions, and explain the operational consequence.
• subprocesses: apply the concept to a development team automating an approval and case-management process with jBPM, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates bpm and jbpm architecture, bpmn modeling, events, gateways, and subprocesses by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how a hidden prerequisite causes the first configuration step to produce an incomplete result and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Build a baseline and capture the initial state for BPM and jBPM Architecture, BPMN Modeling, Events, Gateways, and Subprocesses. Add verified outcomes to the BPMN process model, executable jBPM project, test evidence, and process operations guide.

1. Confirm the scope, versions, access, dependencies, and success criteria.
2. Perform the workflow while recording commands, settings, output, and platform events.
3. Test one expected case and one controlled exception specific to this lesson.
4. Retest the correction and document ownership, rollback, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences BPM concepts in the stated scenario.
• Compare two approaches for events and gateways and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the BPMN process model, executable jBPM project, test evidence, and process operations guide before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, access, dependencies, and starting conditions separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that a hidden prerequisite causes the first configuration step to produce an incomplete result; confirm the cause with a reproducible retest.

Validation Checklist

• The required architecture, access, dependencies, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The BPMN process model, executable jBPM project, test evidence, and process operations guide links conclusions to commands, configuration, logs, or other objective evidence.
• Corrective actions, rollback steps, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply BPM and jBPM Architecture, BPMN Modeling, Events, Gateways, and Subprocesses, explain the observed Red Hat platform behavior, and support the result with a reviewable BPMN process model, executable jBPM project, test evidence, and process operations guide.
