Jakarta EE and the Payara Platform

Shaping the future of the industry through our direct contributions to the Jakarta EE Working Group, as Eclipse Foundation Contributing Members, and as members of the Project Management Committee.

What is Jakarta EE?

Jakarta EE can be defined as a set of open source specifications that enables Java developers to work on cloud native Java enterprise applications. Jakarta EE was formerly Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE).

Jakarta EE specifications are either grouped into a platform specification (Full or Web Platform) or can be an individual specification.

Regardless of the grouping all Jakarta EE specifications consist of

  • APIs and Specification document – defining and describing the specification
  • Technology Compatibility Kit (TCK) – used for testing the code implemented based on the APIs and Specification document
  • Compatible Implementation – implementation that successfully passes the TCK

As enterprises modernize their infrastructure for cloud, microservices and containers, the technological transformation requires a new governance model that provides faster release cycles to keep pace with innovation, along with an open source, community-driven evolution of the platform.

As Contributing Members of the Eclipse Foundation, we’re dedicated to helping shape the future of open source, and continuously invest our resources and expertise to the improvement, innovation, and development of open source technologies and Jakarta EE. Our involvement allows us to support the sustainability of the community, participate in marketing programs, and have direct access to the governance of both the Jakarta EE Working Group and the Eclipse Foundation. Steve Millidge, Director of Payara, is also a Project Management Committee member of Jakarta EE. The Payara team are also contributing to optimizing Enterprise Java for microservices architectures to help enterprises make their journey into the cloud, working closely with customers to shape Jakarta EE to meet their future needs, and are active committers to the Eclipse MicroProfile initiative.

  • Payara Platform Deployment Issues? Try Switching Off XML Validation 01 Dec 2022

    During deployment of Jakarta EE applications to the Payara Server, all the xml files (e.g. web.xml, persinstence.xml) are verified against its schema. Payara Platform includes all standard Jakarta EE schema, so there is typically no reason to download external schema to check against xml files. However, if the application uses external schema, in very rare cases, there may be an error during deployment. In this blog, I describe a quick fix to avoid this. 

  • What’s New in Jakarta REST 3.1 in Jakarta EE 10? 28 Nov 2022

    The Representational State Transfer or RESTful architecture is a stateless, HTTP based communication standard for modern applications. It was originally proposed by Dr. Roy Fielding in hisPhD thesis. It has, over the years, become the default, programming language-agnostic means of enabling machine-to-machine communication. An application written in the Django framework in Python can have REST resources that are consumed by another application written in Java with Jakarta EE. Similarly, a Jakarta EE application can create resources that can be consumed by a C# application.
