Java Web Services

Course Description

Java Web Services develops practical capability in designing, implementing, securing, testing, and operating Java REST and SOAP web services with reliable contracts and observable behavior. The learning path is organized around an order-and-shipping integration exposing REST APIs while supporting a contract-driven SOAP partner.

Learners progress from architecture and process understanding into implementation, validation, troubleshooting, and operational handoff. Every lesson uses the product controls, data structures, business decisions, failure modes, and evidence 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 runbook or design record, and a prioritized improvement action.

What You Will Learn

• Explain and apply HTTP methods, status codes, headers, idempotency, and caching within Java Web Services.
• Validate resource modeling, URI design, JAX-RS annotations, and routing, request and response representations, media types, and content negotiation, and OpenAPI awareness, contract examples, and compatibility decisions through course-specific evidence.
• Explain and apply JSON binding, DTO boundaries, dates, enums, and null handling within Java Web Services.
• Validate bean validation, business rules, and consistent error models, authentication, authorization, tokens, TLS, and secret handling, and service transactions, retries, duplicate requests, and data consistency through course-specific evidence.
• Explain and apply SOAP envelopes, bindings, operations, faults, and message flow within Java Web Services.
• Validate JAX-WS endpoints, service interfaces, and generated artifacts, WSDL and XML Schema contracts, namespaces, and versioning, and WS-Security awareness, interoperability tests, and partner diagnostics through course-specific evidence.
• Explain and apply Java clients, timeouts, connection pools, and serialization tests within Java Web Services.
• Validate unit, integration, contract, negative, and performance testing, retry, circuit-breaker, bulkhead, and fallback concepts, and deployment configuration, logs, metrics, traces, alerts, and support handoff through course-specific evidence.

SkillDynamo Training Approach

The training follows an order-and-shipping integration exposing REST APIs while supporting a contract-driven SOAP partner. Activities combine course-specific demonstrations, guided implementation, hands-on exercises, scenario analysis, validation checklists, failure diagnosis, troubleshooting, and a final improvement plan. Learners document assumptions, settings, outputs, exceptions, corrective actions, security or governance trade-offs, and operational ownership.
