How goes the battle?<\/b>

This post is to show how I created a Helidon demo with a Raspberry PI. A simple web application to control a 14 segments display. This is another blog about Java on Raspberry PI.<\/p>\n

Originally named J4C (Java for Cloud), Helidon was designed to be simple and fast, and the framework supports two programming models for writing microservices: Helidon SE and Helidon MP. Helidon SE is designed to be a microframework that supports the reactive programming model, it features three core APIs to create a microservice; a web server, configuration, and security. Helidon MP, on the other hand, is an Eclipse MicroProfile runtime that allows the Jakarta EE community to run microservices in a portable way; supports the MicroProfile 1.1 specification for building microservices-based applications.
\nBut in both cases, a Helidon microservice is a Java SE application that starts a tinny HTTP server from the main method.<\/p>\n

\nHelidon 2.0 adds significant improvements for both Helidon SE and Helidon MP programming styles<\/small><\/p>\n

Fun Facts<\/b>
\nHelidon is a Greek word for swallow, a type of bird that according to Wikipedia has “a slender, streamlined body and long pointed wings, which allow great maneuverability and very efficient flight”. Perfect for darting through the clouds.<\/p>\n
