Why Jakarta EE still anchors Bangkok banking middleware
Regulated teams favor explicit deployment units — here is how we teach that without nostalgia.
Bangkok teams still ship WAR files because operations wants a portable boundary they can scan before it touches a DMZ. In our Jakarta EE Foundations for Service Teams cohort, we lean into that reality instead of pretending every shop is twelve-factor overnight.
We start with CDI scopes that survive redeploy storms, then layer JAX-RS filters that emit consistent problem+json payloads. Learners keep a decision log comparing Boot auto-configuration with explicit EE wiring — the point is not winners, but traceable trade-offs.
By week four, each participant publishes a Payara Micro bundle with two overlays: one mirroring a Bangkok office subnet and one mimicking a vendor VPN hop. Mentors grade clarity of rollback notes, not cleverness. The capstone stresses incident comms, because middleware engineers still spend more time in chat than in IDEs.
