Jakarta EE is the New Home of Cloud Native Java
After cooperating on a few Jakarta EE specifications (and looking into their implementations as well), I have realized there are certain problems solved over and over again. This leads to duplicity of APIs and to inconsistencies (where the same problem is solved differently by each specification). I think this should be remedied, and a common specification should be created to address these common problems.
The main goal of Jakarta RPC project is to make gRPC easier to use within Jakarta EE ecosystem, by allowing developers to define gRPC services and clients the same way they are defining REST services and clients today -- via annotated classes (a la JAX-RS) on the server, and annotated interfaces (a la Eclipse MicroProfile REST Client) on the client -- and by making them easier to integrate with existing Jakarta EE technologies, such as CDI and Config.
Jakarta Contexts and Dependency Injection v2 defines a powerful set of complementary services that help to improve the structure of application code.
A well-defined lifecycle for stateful objects bound to lifecycle contexts, where the set of contexts is extensible
A sophisticated, typesafe dependency injection mechanism, including the ability to select dependencies at either development or deployment time, without verbose configuration
Jakarta Config is a Java API for working with configurations. It supports externalized configuration allowing applications to use different configurations for different environments (dev, test, prod), and allows reading data from different layered configuration sources such as property files, environment variables, etc.
Eclipse Exousia implements Jakarta Authorization, a technology that defines a low-level SPI for authorization modules, which are repositories of permissions facilitating subject based security by determining whether a given subject has a given permission, and algorithms to transform security constraints for specific containers (such as Jakarta- Servlet or Enterprise Beans) into these permissions.
Eclipse Exousia provides default implementations of these authorization modules and algorithms, as defined and mandated by the Jakarta Authorization specification.
Model-View-Controller, or MVC for short, is a common pattern in Web frameworks where it is used predominantly to build HTML applications. The model refers to the application’s data, the view to the application’s data presentation and the controller to the part of the system responsible for managing input, updating models and producing output.
