Apache OpenWebBeans

Apache OpenWebBeans is an open-source implementation of the Contexts and Dependency Injection (CDI) specification for Jakarta EE. It provides a lightweight, modular, and high-performance CDI container that supports both Java SE and EE environments. Designed for flexibility and extensibility, OpenWebBeans enables developers to build loosely coupled, maintainable, and scalable enterprise applications. It is TCK-compliant and actively used in production systems, including integration with servers like Apache TomEE and Meecrowave
