Develop Web Services and Microservices with Java

Course Description

Develop Web Services and Microservices with Java develops practical capability in developing Java REST, SOAP, and microservice solutions with contracts, validation, security, persistence, resilience, testing, deployment, and observability. The learning path is organized around a customer and order integration exposed through REST, SOAP, and independently deployable Java services.

Learners progress from product architecture and workflow understanding into configuration, development, analysis, validation, troubleshooting, and operational handoff. Every lesson uses the controls, tools, data structures, risks, failure modes, and decisions relevant to this exact Oracle pathway.

The content is independently written for SkillDynamo using the supplied source page for title, update date, and topic alignment. Learners finish with reproducible evidence, a course-specific implementation record or runbook, and a prioritized improvement action.

SkillDynamo Training Approach

The training follows a customer and order integration exposed through REST, SOAP, and independently deployable Java services. Activities combine product-specific demonstrations, guided implementation, hands-on exercises, scenario analysis, validation checklists, structured troubleshooting, solution review, and a final improvement plan. Learners document assumptions, settings, commands or transactions, outputs, exceptions, corrective actions, security and governance trade-offs, rollback needs, and operational ownership.
