AD183 Red Hat Application Development I: Programming in Java EE — Lesson 4: Testing, Packaging, JBoss EAP Deployment, Logging, Troubleshooting, and Delivery

Learning Objectives

• Operate, troubleshoot, document, and improve testing, packaging, and JBoss EAP deployment.
• Apply logging and troubleshooting and delivery while preserving reviewable technical evidence.
• Recognize and correct the risk where the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete.

Detailed Topics

• testing: apply the concept to a Java team building and deploying a maintainable enterprise application on Red Hat JBoss EAP, record the relevant settings or decisions, and explain the operational consequence.
• packaging: apply the concept to a Java team building and deploying a maintainable enterprise application on Red Hat JBoss EAP, record the relevant settings or decisions, and explain the operational consequence.
• JBoss EAP deployment: apply the concept to a Java team building and deploying a maintainable enterprise application on Red Hat JBoss EAP, record the relevant settings or decisions, and explain the operational consequence.
• logging: apply the concept to a Java team building and deploying a maintainable enterprise application on Red Hat JBoss EAP, record the relevant settings or decisions, and explain the operational consequence.
• troubleshooting and delivery: apply the concept to a Java team building and deploying a maintainable enterprise application on Red Hat JBoss EAP, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates testing, packaging, jboss eap deployment, logging, troubleshooting, and delivery by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Run an operational review and produce support-ready evidence for Testing, Packaging, JBoss EAP Deployment, Logging, Troubleshooting, and Delivery. Add verified outcomes to the Java EE application repository, integration tests, deployment package, and developer handover 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 testing in the stated scenario.
• Compare two approaches for logging and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the Java EE application repository, integration tests, deployment package, and developer handover guide before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check monitoring, troubleshooting, rollback, ownership, and handover separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete; confirm the cause with a reproducible retest.

Validation Checklist

• The required monitoring, troubleshooting, rollback, ownership, and handover were checked and recorded.
• The normal path and a course-specific exception were tested.
• The Java EE application repository, integration tests, deployment package, and developer handover 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 Testing, Packaging, JBoss EAP Deployment, Logging, Troubleshooting, and Delivery, explain the observed Red Hat platform behavior, and support the result with a reviewable Java EE application repository, integration tests, deployment package, and developer handover guide.
