This document discusses the transition from Java EE to Jakarta EE. It provides an overview of the history and evolution of Java EE standards. It then details the formation of Eclipse EE4J and Jakarta EE to take over stewardship of Enterprise Java from Oracle. It outlines the goals of open governance and more agile innovation. Finally, it discusses Red Hat's involvement in projects like WildFly Swarm and EAP Continuous Delivery to support Jakarta EE.

Eclipse EE4J - Mission
● Create (and evolve) standard EE APIs, RIs and TCKs
○ Using Java EE 8 as baseline
○ Enabling the development of server-side & cloud-native apps
● Come up with a nimble, flexible, open and vendor independent process
○ That evolves the platform in a compatible way
● Build up the new EE4J community of developers, vendors, end-users
○ Enabling competing vendors and tech providers to provide innovations

18. Eclipse EE4J - Key Principles
● Opensource
○ Transparency, Meritocracy, Community-Driven
○ Code first, specifications second
○ No Spec Lead having central control of IP
● Compatibility
○ Value of Spec+RI+TCK & Brand Compliance
● Innovation
○ Ensure Java's future as a cloud native development platform
● Agility
○ Just enough process, faster iterations

24. Jakarta EE Directions
What Next?

25. Java EE - The Good

26. Standardization (still) matters!

27. Java EE - The Bad(ly missing)
27*https://jakarta.ee/news/2018/04/24/jakarta-ee-community-survey/

28. Jakarta EE & Eclipse Microprofile
● Eclipse Microprofile APIs can feed into Jakarta EE
○ With faster Eclipse Microprofile acting as incubator for slower Jakarta EE
● Or the two efforts could eventually merge
○ TBD by the Jakarta EE / Microprofile communities
Both need to adapt to operate in an
increasingly containerized, distributed,
proxied, managed, services-based
environment
28

29. Java EE - The Ugly
29*https://jakarta.ee/news/2018/04/24/jakarta-ee-community-survey/

30. Optimized Runtimes for Jakarta EE
● Memory Footprint & Start-up times vastly improved over the years
● We should increase modularization & decoupling of APIs
○ Allows runtime optimizations, turning things off, lazy loading, parallel boot, etc.
● Allow compose-ability in the spec level - bundle only the used APIs
○ How do you test arbitrary combinations of capabilities?
○ Maybe we need to define new profiles

31. Other Jakarta EE futures
● Support for Reactive Streams & Async APIs
● ServiceMess Integration (Istio)
● New profiles for Mobile & IoT
● Transactions for Microservices?
● Replacements for legacy, like CORBA/IIOP
● Developer productivity improvements

32. Jakarta EE @ Red Hat
How are we involved

33. WildFly Swarm (Thorntail)
● Drives our Eclipse Microprofile implementation efforts
● Promoting shared API implementations across projects
● Researching further runtime reduction techniques
● Finalizing support for MP v1.3
● Looking towards v1.4 & 2.0
33

34. WildFly.Next
● Moving to Quarterly timeboxed releases
● Merge only completed features to main branch
● Formalize and enforce topic-branch testing

○ EE8 Chunk 1 (Servlet, CDI, JSON-B, JAX-RS, BV, JSF)
○ Continuous feature delivery process
● WildFly 13, May 30, 2018 - DELIVERED
○ EE8 Chunk 2 (JPA, EE Security)
○ New server assembly infrastructure
● WildFly 14, Aug 29, 2018

● Targeting primarily OpenShift Cloud based deployments
● Every 3rd or 4th release rolls into a traditional EAP release
● Initially Tech Preview
