Developing Applications for the Java EE 7 Platform Ed 1 — Lesson 4: JAX-RS, JAX-WS, Security, Testing, and Deployment

Technical Scope

• JAX-RS resources, providers, content negotiation, validation, and exception mapping
• JAX-WS contracts, handlers, SOAP faults, interoperability, and client generation
• declarative security, roles, identity propagation, transport controls, and secrets
• Arquillian-style testing, deployment packaging, logging, health checks, and release rollback

Instructor Demonstration

The instructor diagnoses JAX-RS resources, providers, content negotiation, validation, and exception mapping, then connects it to JAX-WS contracts, handlers, SOAP faults, interoperability, and client generation. The demonstration captures the exact configuration, transaction, command, query, log, or screen evidence needed to prove intended behavior and the applicable control boundary.

Applied Workshop

Learners execute a guided lab focused on JAX-WS contracts, handlers, SOAP faults, interoperability, and client generation and declarative security, roles, identity propagation, transport controls, and secrets. The exercise introduces a realistic exception related to Arquillian-style testing, deployment packaging, logging, health checks, and release rollback and requires a reversible correction supported by before-and-after evidence.

1. Confirm scope, identities, data, dependencies, controls, and expected result.
2. Perform the product-specific configuration or analysis and record exact steps.
3. Validate functional behavior, security, data integrity, and operational observability.
4. Introduce the defined failure condition, diagnose the cause, and apply a safe correction.
5. Document rollback, acceptance evidence, unresolved risk, and ownership.

Validation Standard

Acceptance requires accurate handling of declarative security, roles, identity propagation, transport controls, and secrets, traceable proof for JAX-RS resources, providers, content negotiation, validation, and exception mapping, and a repeatable recovery path for Arquillian-style testing, deployment packaging, logging, health checks, and release rollback. Results must be understandable to both implementers and operational support teams.

Failure Analysis

Learners compare symptoms, logs, state, dependencies, and recent changes when Arquillian-style testing, deployment packaging, logging, health checks, and release rollback occurs. The final diagnosis must separate the immediate fix from the preventive control.

Practical Outcome

The completed output is a tested jax-rs, jax-ws, security, testing, and deployment implementation or analysis, with validation evidence, troubleshooting notes, rollback guidance, and a concise operational handover.
