Helidon MP Introduction

Helidon MP is an Eclipse MicroProfile runtime that allows the Jakarta EE community to run microservices in a portable way.

About Helidon MP Components

Helidon MP 2.6.14 is an implementation of the MicroProfile specification and supports MicroProfile 3.3. Since MicroProfile has its roots in Java EE, the MicroProfile APIs follow a familiar, declarative approach with heavy use of annotations. This makes it a good choice for Java EE developers.

Helidon has added additional APIs to the core set of Microprofile APIs giving you all the capabilities you need for writing modern cloud native applications.
