Baking a Java EE 8 Micro Pi

on YouTube ↗01h 22m

" summary

A Raspberry Pi cluster runs Payara Micro (~60 MB jar) with Hazelcast clustering and a stock-ticker microservice: an EJB timer fires every second and publishes CDI events annotated @Outbound that Hazelcast delivers to @Inbound listeners on other nodes, a clustered singleton ensures one producer, JSON-B serializes stock objects, JAX-RS SSE broadcaster pushes updates to clients, and MicroProfile Config (including a cluster-backed source) stores runtime endpoints. The live demo fails from power/hardware gremlins but the code is on GitHub and a working demo is on the Payara stand.
