HTTP QUERY Method Explained: RFC 10008, Ecosystem Adoption, and a Quarkus Implementation

Fri, 31 Jul 2026 08:00:37 +0000

When you build a search API, you usually start with HTTP GET, the natural choice for a read operation: it is safe, idempotent, and cacheable. Then the search form grows, filters multiply, and nested criteria appear. Since using GET means placing the query inside the URI, a length limit problem emerges. Worse, placing sensitive query values in the URI increases the chance of exposure through access logs, browser history, proxies, and monitoring systems. Because the HTTP protocol does not forbid it, sending a body with GET may look like a way out, but building your design on behavior the standards leave undefined is not a recommended practice. Elasticsearch’s GET-with-body search API is a well-known example, and Elastic’s own documentation openly acknowledges the problem:

The Java Story: A Film About All of Us

Thu, 09 Jul 2026 08:43:59 +0000

Every so often a story comes along that belongs to an entire community rather than any one company or person. The Java Story documentary by CultRepo is one of those. On July 17th at 7pm UTC, the official Java documentary premieres live on YouTube - if you’ve spent any significant part of your career working with Java (and I assume most Foojay readers have!), I really think you’d want to watch it!

Jurassic JDK: Migrate or Extinct

Fri, 26 Jun 2026 07:28:00 +0000

65 million years ago, dinosaurs didn’t adapt. They’re gone. Your JDK 7 app is giving the same energy. 🫠

I spent a year and a half migrating more than 15 projects in production. Full time. Real teams, real deadlines, real 2am breakage. This is everything I wish someone had written before I started.

Why Are We Still Here? 👀

Walk into any company with a codebase older than 5 years and you’ll hear the same thing:

What's New In The June 2026 Azul Payara Release?

Wed, 24 Jun 2026 11:28:52 +0000

The June 2026 cycle ships the first regular monthly release of the Payara 7 line, plus a critical security fix that lands across every supported branch. Azul Payara 7.1.0 continues the Jakarta EE 11 line that went generally available in May, and is joined by Azul Payara Community 7.2026.6, Azul Payara 6.39.0, Azul Payara 5.88.0, and Azul Payara 4.1.2.191.56.

A single security fix, backported from Payara 7 down to Payara 4, runs through every release in this cycle. Two supported lines, 5.88.0 and 6.39.0, also carry a behaviour change to the server “ready” signal that a minority of deployments will want to read before upgrading.

Jakarta EE is Ready for AI – Five Talks from OCX26 That Prove It

Tue, 02 Jun 2026 11:41:01 +0000

Back in April I had the pleasure of attending Open Community Experience 2026 in Brussels - the Eclipse Foundation’s flagship open source conference. It’s always good to be in a room (or a few rooms 😉 ) with people who really care about the technology they work with. Several of my colleagues and friends were speaking - watching them present work they’ve spent serious time on is one of the better parts of this community.

The latest version of Eclipse GlassFish 8.0.2 was released on May 5, 2026, with fixes for several critical vulnerabilities. It builds on top of a lot of subtle work and improvements in GlassFish components like the Eclipse Grizzly HTTP framework, or in related components like Eclipse OpenMQ message broker and Eclipse ORB (CORBA) for remote EJB calls. The release of GlassFish 8.0.2 serves as further evidence that GlassFish remains an actively evolving platform, backed by the dedicated maintenance and commercial support of the OmniFish team. As I was deeply involved in this release, I’d like to share a deeper look into the technical advancements within this new version.

A New Chapter for the Payara Community

Mon, 18 May 2026 06:51:51 +0000

Something has been in the works since Azul completed its acquisition of Payara in December 2025 , and today we’re ready to share it: the community edition of Payara has a new name and logo – but not so very different from the one you already know!

Payara Platform Community is now Azul Payara Community , made up of two distributions you already know and love - Azul Payara Server Community and Azul Payara Micro Community - plus the tooling and connectors that go with them.

What's New in the May 2026 Payara Platform Release | Azul

Thu, 14 May 2026 11:40:02 +0000

The May 2026 release is the largest Payara milestone since the project’s inception. Azul Payara Server 7 and Azul Payara Micro 7 ship as generally available, both certified against Jakarta EE 11. This is the first major Payara product release under the Azul brand, arriving six months after Azul completed its acquisition of Payara in December 2025.

Azul Payara Community 7 (download here ), the open-source distribution, was the first implementation of any kind to certify across all three Jakarta EE 11 profiles (Full, Web Profile, Core Profile). Azul Payara Server 7 brings that certification to a commercially supported product with enterprise SLAs, making it the first commercially supported Jakarta EE 11 runtime from a major enterprise application server vendor. Both products ship with MicroProfile 6.1 (Config, Metrics, Health, Fault Tolerance, JWT, OpenAPI, REST Client, Telemetry Tracing). Azul Payara Server 7 holds Final TCK certification across all three profiles:

AWS Nitro and CPU Graviton Meets Unikernels

Fri, 10 Apr 2026 16:26:25 +0000

AWS Nitro and CPU Graviton Meets Unikernels: Java and Quarkus on ARM64 AWS Graviton with Nanos Unikernel

Java and Jakarta EE Truly Meet Unikernels

The key message of this article is simple and strong:

any Java or Jakarta EE application is already ready to benefit from the advantages of unikernels.

Java and Jakarta EE, including modern frameworks such as Quarkus, can immediately take advantage of the unikernel model without waiting for new languages, new runtimes, or radical rewrites.

Spring Boot Actuator Health for MicroProfile Developers

Thu, 26 Mar 2026 09:30:00 +0000

If you worked with MicroProfile Health, you already understand the value of exposing application health information through standardized endpoints. You know about liveness, readiness and startup probes. You implemented the HealthCheck interface and annotated your procedures with @Liveness, @Readiness and @Startup. Spring Boot Actuator follows a similar philosophy but takes a different architectural approach. This post will help you map your MicroProfile Health knowledge to Spring’s world.

The Conceptual BridgeThe Conceptual Bridge

At its core, Spring Boot Actuator serves the same purpose as MicroProfile Health: it provides a mechanism for validating the availability and status of your application in containerized environments. Both specifications recognize that modern cloud platforms like Kubernetes need machine-readable health information to make decisions about pod lifecycle management.

Eclipse GlassFish: This Isn’t Your Father’s GlassFish

Tue, 24 Mar 2026 15:30:49 +0000

GlassFish is an application server with a long history and has always had a special role in the Java world as the reference implementation of Java EE, being one of the most popular Java EE servers. Since Oracle lost interest in the project several years ago, developers and organizations have held certain beliefs about GlassFish, often based on their experiences with older versions.

If you still think of GlassFish as a slow, unsupported, and purely for-development application server, it’s time to take a fresh look. At OmniFish, we’ve been working hard to change that perception since 2022. The Eclipse GlassFish of today, particularly from version 7.0 onwards, is a completely different platform, and we’re proud to show you what we’ve helped to build with the rest of the Eclipse GlassFish contributors.

Wed, 11 Feb 2026 13:50:41 +0000

Profiling a Java Application Running Inside an Unikernel with JProfiler

Unikernels are often associated with minimalism and tight resource control.

But can we profile a Java application running inside a unikernel using a standard JVM profiler?

The answer is yes.

In this guide, we will walk step by step through profiling a Quarkus

application running inside a Nanos unikernel using JProfiler and
IBM Semeru JRE 25 (OpenJ9).

No special hacks. Just standard JVM tooling.

Enterprise Java in Practice

Thu, 29 Jan 2026 10:11:40 +0000

Enterprise Java has matured into one of the most stable and widely adopted ecosystems in software development. Yet for many teams, the biggest challenges no longer come from the language itself, but from the complexity of the environments built around it.

Modern enterprise Java teams are dealing with a mix of legacy Java EE applications, Jakarta EE runtimes, microservices, container platforms, cloud-native deployments, and increasingly sophisticated DevOps pipelines. The result is an ecosystem that is powerful, but often fragmented across frameworks, runtimes, tooling, and operational models.

What’s New in the January 2026 Payara Platform Release?

Mon, 26 Jan 2026 14:37:09 +0000

Java and Jakarta EE and the Evolution of the Cloud with Nanos Unikernel

Tue, 06 Jan 2026 20:51:09 +0000

The evolution of the Java and Jakarta Enterprise ecosystem is converging toward an increasingly simple, efficient, and scalable architecture that improves security, delivers higher performance, and reduces hardware and infrastructure costs.

For years, Kubernetes has been considered the de‑facto standard for modernizing Java applications in a cloud‑native direction. However, Kubernetes is not the only way to achieve scalability, continuous upgrades, and isolation. An alternative approach — often underestimated — is to leverage the hypervisors already included and fully managed by major cloud providers , using Unikernel images based on Nanos .

From Spring Boot To Jakarta EE 11

Fri, 28 Nov 2025 08:11:53 +0000

If you’ve been living in the Spring ecosystem, you’re used to fast project setup. Spring Initializr gives you a sleek interface, some starter dependencies and a running project within minutes. Now you’re moving to Jakarta EE, where do you begin?

In this blog, you’ll see how Spring developers can create Jakarta EE applications with the same ease they’re used to from Spring Initializr.

Let’s be honest: Spring Boot abstracts away so much of the setup pain that you forget it’s even there. You don’t worry about the underlying servlet container, dependency versions or deployment descriptors, as Spring Boot handles it all.

Why Java is Still Worth Learning in 2025: A Developer's 25-Year Journey

Mon, 04 Aug 2025 06:32:05 +0000

I’ll be honest - my first encounter with Java in 1999 wasn’t love at first sight. It was during a university distributed systems course, and coming from a background in assembler and C, Java felt bloated, slow, and frankly untrustworthy. That “automatic memory handling” seemed like dangerous magic I couldn’t control. After years of meticulously tracking every allocated memory block, the idea that the runtime would handle memory management felt like giving up control to forces I didn’t understand.

For the first eight years of my career, I stubbornly stuck with C, convinced that Java was just a passing trend for developers who couldn’t handle “real” programming.

Performance Best Practise No. 1: Optimize Database Operations

Wed, 11 Jun 2025 13:24:32 +0000

Database operations are a very critical part of most applications in regards of performance. There are multiple reasons why database operations can significantly contribute to lower performance:

The database often runs on a remote server, slowing down communication with the database and the data transfer
Establishing individual connections to a database can take a significant portion of time compared to running the whole database query
Database queries can run for a long time
Network communication is unstable and may required restarting queries in case of network failures

You can address the above issues and boost Jakarta EE database performance by leveraging the following best practices.

AI-based Images generation with Quarkus and OpenAI DALL.E

Mon, 21 Aug 2023 07:38:07 +0000

In this article, we explore how to integrate OpenAI API with Quarkus. We will create a Quarkus application using the new REST Client Reactive to invoke the OpenAI DALL.E API for images generation.

OpenAI API Overview

Before jumping into the code, let’s explore the OpenAI Create Image API and how it works.

Create Image Request

The body request is made of the following parameters:

prompt: the only required parameter is the description of the desired image (max 1000 characters)
n: number of desired images (from 1 to 10)
size : the size of a generated image (default 1024x1024, also admitted 256x256, 512x512)
other parameters are:
response_format: to specify the response image format (default url, also admitted b64_json)
user: identifier to track user activities.

To authenticate with the API, we’ll generate an API key . We’ll set this key in the Authorization header while calling the API.

Getting Started With Apache Camel On Jakarta EE 10

Mon, 24 Jul 2023 10:20:06 +0000

Apache Camel is an open source enterprise integration framework that helps you connect different systems and applications together with as little effort as possible. It provides a simple and powerful way to define and implement message-based routing and mediation rules. It is an implementation of the patterns described in the book Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf.

In simple terms, Apache Camel acts as a “translator” or “bridge” between different systems. It allows you to easily route, transform, and process messages as they move from one system to another. It supports a wide range of communication protocols and data formats (JSON, XML, YAML, etc.), making it easier to integrate different technologies and applications.

Upgrade to Jakarta EE 10 and GlassFish 7: Easier Than You Think!

Tue, 27 Jun 2023 07:29:48 +0000

Upgrading to Jakarta EE 10 from an older version of Jakarta EE or Java EE can be a bit tricky and may require some extra attention to detail. But don’t worry, we’ve got you covered!

In this series of articles, we’ll explain everything you need to know before upgrading to Jakarta EE 10 and guide you to complete the upgrade successfully and in almost no time.

Types of challenges

The challenges with upgrading to Jakarta EE 10 or to Eclipse GlassFish 7 fall into these 3 main categories:

Exploring Java Records In A Jakarta EE Context

Wed, 14 Jun 2023 21:08:35 +0000

Java Records, one of the major highlights of the Java 16 release, provides a concise and immutable way to define classes for modelling data.

This conciseness lends itself useful in a typical Jakarta EE application that can have a number of layers that need to share data.

For example, the data layer might want to return a subset of a given data set to a calling client through a data projection object.

"Transitioning to Java": My First Book!

Wed, 24 May 2023 08:01:58 +0000

When I retired from the classroom in 2021, I had no intention of sitting on a rocking chair on my front porch.

I looked for speaking opportunities, became a member of the JCP EC, and continued thinking about ways to enhance Java teaching.

I also wanted to write a book. I approached a number of publishers with my idea for a beginner’s book. I even wrote a sample chapter and publsihed it on my blog, https://www.omnijava.com/2021/10/20/java-for-beginners-my-unsuccessful-book-proposal/ .

Getting Started With Jakarta EE 10 - Jakarta REST

Wed, 12 Apr 2023 07:42:29 +0000

Jakarta EE 10 was released in September of 2022 as the first major release of the venerable Enterprise Java development platform since it was moved to the Eclipse Foundation.

As a major release, it did come with a slew of updates to almost all the major specifications, including Jakarta REST.

In this article, we take a look at how to get started developing RESTful web services on the Jakarta EE Platform using the Jakarta REST API.

How Not To Skip A Message Even If Your Data Centre Fails

Fri, 07 Apr 2023 15:21:31 +0000

A high level of availability of IT services is crucial to prevent disruptions of service that can lead to financial losses, business opportunity losses, data loss, and reputational damage.

A business’s downtime cost can vary depending on its size, nature and the length of the downtime.

Studies by Network Computing, the Meta Group, and Contingency Planning Research have identified financial services and telecommunications as industries with the highest revenue loss during downtime, demonstrating the importance of FIX engine high availability.

A Quick Look At Faces (JSF) 4.0 In Jakarta EE 10

Fri, 17 Feb 2023 09:07:05 +0000

Jakarta EE 10 shipped with the fourth major release of its component based web framework Jakarta Faces.

Hitherto known as Jakarta Server Faces, and Java Server Faces before that, Jakarta Faces , or just Faces, version 4.0 is the first major version with API change since version 2.3 in Java EE 8.

Among the major changes in this version are the following.

Issue #1581 : New API to programmatically create Facelets
Issue #1508 : New automatic extensionless mapping
Issue #1509 : New annotation @ClientWindowScoped
Issue #1555 : New attribute <h:inputFile multiple="…">
Issue #1556 : New attribute <h:inputFile accept="…">
Issue #1559 : New tag <f:selectItemGroups>
Issue #1560 : New attribute <h:inputText type="…">
Issue #1563 : New tag <f:selectItemGroup>
Issue #1565 : Skip type attribute from <link> and <script> when doctype is HTML5

There were also some pruning of the API such as:

What’s New in Jakarta REST 3.1 in Jakarta EE 10?

Thu, 05 Jan 2023 11:30:17 +0000

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 his PhD 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.

EJB support in Piranha via CDI

Tue, 15 Nov 2022 14:14:42 +0000

Enterprise Beans was once the face of Java EE, but as we discussed in the previous article , is currently de-emphasised in Jakarta EE.

However, since there’s so much existing code using Enterprise Beans, a certain level of support is still desired.

Piranha Cloud , a relatively new runtime supporting Jakarta EE, takes a somewhat novel approach to Enterprise Beans. Instead of implementing a separate container, Piranha Cloud, via the OmniBeans project, maps Enterprise Beans annotations to equivalent functionality in CDI itself, or to technologies in Jakarta EE leveraging CDI (such as Jakarta Transactions).

The Future of EJB

Thu, 10 Nov 2022 16:06:56 +0000

EJB, or Enterprise Beans, are Java classes with a number of container provided services attached to them, such as transactions, remoting and security. In this article we will take a look at what we can expect for EJB in the future.

Once upon a time EJB was almost synonymous with what was called Java EE or J2EE back then (Jakarta EE now). It suffered from many issues though, although it did incrementally got better. We’ll explore some of those issues next.

What is Jakarta RPC?

Thu, 10 Nov 2022 15:32:52 +0000

Originally written by Alfonso Altamirano

Jakarta EE is at the forefront of innovation in enterprise Java. This means staying close to the community and working on new specifications to meet developer needs.

Now that Jakarta EE 10 has been released, the first release to bring new features since the move to the jakarta namespace, all the upcoming releases of Jakarta EE will bring new features. The improvements will keep arriving!

Ignore Infrastructure, Focus on Code, with Jakarta EE and Payara

Tue, 09 Aug 2022 09:59:12 +0000

Java EE, now Jakarta EE, makes it possible for developers to focus purely on the development of a Java enterprise application, solving the business logic without needing to think about infrastructure and operations when writing code.

Payara Cloud extends this philosophy by also eliminating the need to worry about infrastructure and operations when preparing your application to run in the cloud.

Together, Jakarta EE and Payara Cloud let you focus on writing code and delivering solutions to business challenges from the moment you write your first piece of code to the day people are using your application successfully on the cloud.

Jakarta Concurrency: Present and Future

Wed, 13 Jul 2022 13:38:25 +0000

Jakarta EE , previously Java EE, is a set of specifications that enables the world wide community of Java developers to work on cloud native Java enterprise applications.

It is an open source project maintained by the Eclipse Foundation.

Jakarta Concurrency is a small, but fundamental, specification under the Jakarta EE umbrella.

As project lead, I provide more information on what it is, its future and how to be involved.

Top 7 Features in Jakarta EE 10 Release

Tue, 28 Jun 2022 08:33:31 +0000

Java EE has been a dominant force behind all enterprise development in Java. Lately, it was renamed to Jakarta EE , while transitioning to the Eclipse Foundation.

This transition opened the door to open governance, open compatibility testing (the earlier Technology Compatibility Kit was closed source), and of course, open-source contributions. That means no specific vendor has more influence than any other and it is a more distributed process now.

Easy Jakarta EE Integration Testing

Wed, 04 May 2022 14:41:49 +0000

One major issue when developing modern enterprise applications is the “works on my machine” problem: when an application works well on your machine but is not functional in production or even on a colleague’s machine.

An even more prevalent problem is to maintain the quality of ever-changing applications during development and maintenance.

This is especially prevalent when Jakarta EE applications are developed and not properly tested in an isolated and cohesive manner.

Migrating from Java EE to Jakarta EE with IntelliJ IDEA

Fri, 08 Apr 2022 17:02:37 +0000

In this post, we’re going to migrate some sample code from the javax namespace to jakarta. If you want the history on this change, check out this helpful blog post from Java Magazine. Fundamentally the Java Persistence API was renamed to Jakarta Persistence API meaning that the javax namespace changed to jakarta for frameworks whose APIs have moved to Jakarta EE (which is not all of them).

However, Apache Tomcat recently released version 10 which updated package names from javax to jakarta. SpringBoot also made this change in version 6.

Jakarta Concurrency: Present and Future

Wed, 23 Feb 2022 14:15:13 +0000

Jakarta EE , previously Java EE, is a set of specifications that enables the world wide community of Java developers to work on cloud native Java enterprise applications. It is an open source project maintained by the Eclipse Foundation.

Tomcat and TomEE Clustering Automation in the Cloud

Mon, 30 Aug 2021 07:18:36 +0000

Apache Tomcat is an open-source application server maintained by the Apache community. It is one of the most popular solutions for hosting Java applications due to its ease-of-use and lightweight yet versatile functionality. However, if you run the projects based on Jakarta EE 8 (or higher), you may be interested to use TomEE server with built-in required enterprise technology that isn’t found in Tomcat.

Due to the extreme popularity of these stacks globally, and within Jelastic PaaS in particular, we’ve decided to share tips on how to install automatically clustered Tomcat and TomEE servers to get a highly available solution that can efficiently serve a large number of users, process high traffic, and be reliable.

Introduction to New AutoScale Feature Available in Payara Server

Wed, 23 Jun 2021 07:47:09 +0000

Running your application sometimes requires multiple instances to handle the requests of the users. Within the Payara Platform, the Domain Data Grid helps you configure your environment to run your application in a cluster. Besides the setup of a cluster itself, many applications can benefit from an environment that scales dynamically.

The number of instances must increase when the application usage peaks and should decrease when activity is low to reduce the resource usage and the corresponding costs associated with it. The introduction of the AutoScale feature in Payara Server Community 5.2021.4 helps us achieve this dynamic scalability.

Jakarta EE Application Deployment to Kubernetes Cluster in Jelastic PaaS

Wed, 16 Jun 2021 06:58:31 +0000

Recently, we were asked to sponsor cloud hosting of a Jakarta EE project, called Cargo Tracker . Being a member of Jakarta EE Working Group, Jelastic wanted to support the community and thus we started to run this application at one of our service providers (Scaleforce ).

Cargo Tracker is now deployed to Kubernetes on the cloud using GitHub Actions. Thanks sponsors Jelastic and Scaleforce! https://t.co/zhnmj0TB7Z // @Jelastic, @scaleforce pic.twitter.com/BRGkwxban2

Automatic WildFly Managed Domain Clustering & Scaling in Containers

Mon, 31 May 2021 08:08:12 +0000

Nowadays it’s easy to get up and running WildFly standalone server in a container. But what if you need to enable clustering in Managed Domain mode, which is one of the key features of Jakarta EE in general? That is a not so easy task. Some people claim it’s nearly impossible in the cloud-native world, because Jakarta EE clustering was designed before the containers era. The old question at the official developers portal is still not answered with any adequate instructions, just proving the presence of the issue.

Getting Started with Jakarta EE 9: Context & Dependency Injection

Wed, 26 May 2021 06:56:27 +0000

In the next part of the “Getting Started with Jakarta EE ” series, we discuss Context and Dependency Injection (CDI) and the CDI specification.

The CDI specification is an important backbone of Jakarta EE as it brings several specifications together. Over the years, it has become more and more important as an increasing number of specifications started using CDI as the basis for it.

We will also tell you a bit about the different scopes, the interceptor mechanism, and the Event system.

Announcement: Jakarta EE 9.1 Has Been Released!

Tue, 25 May 2021 14:57:35 +0000

Join us in celebrating a new release of Jakarta EE!

This gives developers more flexibility when migrating from previous Jakarta EE releases.

In order to upgrade to the new version, simply change the dependency version in your pom.xml to 9.1.0. If you are upgrading from a version prior to Jakarta EE 9, follow the migration steps for the namespace change from javax.* to jakarta.*.

Why Java Developers Continue to Rely on Jakarta EE

Wed, 05 May 2021 07:53:59 +0000

Over the past year, the Eclipse Foundation spoke to leading Java developers around the world to discuss why they rely onJakarta EE and the unique benefits of using Jakarta EE technologies. Their input is captured in our white paper, which describes the important advantages Jakarta EE offers today and for the future.

Download the Jakarta EE white paper!

They’re Looking Ahead, Not Back

With Jakarta EE’s long history as Java EE, it’s sometimes easy for developers to dismiss the technology as yesterday’s approach. But Jakarta EE technologies are embedded, and relied upon, in a way no other technologies are. Here are some examples you might not be aware of:

Java Garbage Collection Types & Settings Customization via Jelastic PaaS

Thu, 29 Apr 2021 07:54:20 +0000

Performance and price are two big considerations in application hosting that always matter. And, often, we question ourselves on how to decrease the spends, without affecting the performance of your apps at the same time. In this article, we’d like to address automatic memory management for Java applications hosted with Jelastic using garbage collection.

Let’s clarify what garbage collection is, what it does for Java applications and how it works within Jelastic PaaS.

Take the 2021 Jakarta EE Developer Survey

Mon, 26 Apr 2021 07:47:29 +0000

Getting Started with Jakarta EE 9: Hello World

Wed, 07 Apr 2021 08:55:22 +0000

The release of Jakarta EE 9 , at the end of 2020, was in many ways a historic event. The Java Enterprise framework is already 20 years old, having its first release in 1999. It has changed names a few times but the main concepts of the first release can still be found in this new release. During all those years, it has adapted itself to keep it up to date but has always adhered to its main principle of stability and backward compatibility.

How to Convert a 3rd Party Library to the New Jakarta Namespace

Mon, 08 Mar 2021 16:56:53 +0000

The release of Jakarta EE 9 breaks a tradition of Java Enterprise. A legal requirement of the Java EE code donation from Oracle to the Eclipse Foundation is the change of the namespace of javax tojakarta.

But the change of the package and XML namespace in Jakarta EE 9 is only the beginning. The change of the namespace allows for new development and functionality, but all frameworks and libraries using one of the Java Enterprise specifications also need to be adjusted to the new version.

What Are Your Java Predictions for 2021: Jakarta EE

Mon, 28 Dec 2020 09:30:18 +0000

To celebrate the world of Java and predict our highlights for 2021, several key Foojay participants will share their thoughts and hopes during the coming days on Foojay, starting with Frank Delporte, Foojay Community Manager for the Raspberry Pi , and now continuing with Jadon Ortlepp, Foojay Community Manager for Microservices, who here provides the predictions of his Payara colleagues on Jakarta EE in 2021.

“Jakarta EE will start driving improvements in APIs and Project Loom will drive new releases of many frameworks.

Java developers may stop having to worry about Kubernetes as it is abstracted away as ‘just infrastructure’.

As ever, the death of Java is predicted but Java is set to remain a top 3 programming language in 2021.”
