Java EE 8 has improved its APIs and programming models to suit the needs of modern enterprise applications. It provides an infrastructure for microservices and cloud-based environments.

Java EE 8 has a new security API and a new standardized API for binding JSON to model objects. The Servlet 4.0 API now comes with HTTP/2 support. A new Reactive rest client API and asynchronous API have been introduced in this release of the platform as well.

Java EE 8's new dependency injection (DI) feature, along with its improved security and reliability, makes it easier to develop applications.

Java EE 8 is also now aligned with Java 8, which means that Java 8 features, such as streams, lambda, and the new data-time API, can be used in Java EE 8's APIs as well, and it has enhanced support for these features.
