It's also the month we launched a free trial of our fully managed Jakarta EE cloud native application runtime, Payara Cloud. You can now try it out for free, with 15 days available to you as a trial. Check it outhere.
So, you're a Java developer, or maybe you're aspiring to be one. Either way, you've probably faced the challenge of managing multiple versions of Java on your machine. One project requires Java 8, but another needs Java 11, yet another requires Java 17. The open-source library you're keen on contributing to needs yet another version. What do you do? You start juggling environment variables, and before you know it, your system is a tangled mess of configurations. Not fun, right?
And let's not even get started on the difference between JRE and JDK. It's easy for beginners to get confused about the distinction between the two. The JRE (Java Runtime Environment) is sufficient if you just want to run Java applications, but if you're going to be developing them, you'll need the JDK (Java Development Kit). The JDK includes everything the JRE has, plus additional tools and utilities for developers like the Java compiler, or javac.
Tired of all this complexity? Let me introduce you to SDKMan!, a version manager that streamlines the process, making it a breeze to manage multiple Java versions on your machine. Not just Java, SDKMan! can be used to manage a lot more kits and tools such as Maven. In this blog post however, we see how to use SDKMan! to effortlessly manage different versions of Java on the same machine.
For this first ever episode of Payara Podcast, we had a chat with Rachel Stephens, Senior Analyst at RedMonk (the developer-focused industry analyst company) and Steve Millidge - Payara Founder and CEO.
We talked about open source, focusing on using it in the context of enterprise. We talked about public perception of open source, common myths surrounding the use of open source technologies for enterprise businesses, security aspects of using open source and much more.
In the realm of Jakarta EE development, orchestrating a smooth interaction between your application and the server is paramount. The Payara IntelliJ Plugin is one such tool that facilitates seamless integration between the Payara Server and the IntelliJ IDEA. This plugin empowers developers to efficiently manage and deploy Jakarta EE applications, and troubleshoot issues right from their development environment. In this blog post, we will explore the various features of the Payara IntelliJ Plugin and provide a step-by-step guide on how to make the most of its capabilities.
Coming fresh and energised from summer vacation, the Payara engineering kitchen presents to you the August 2023 release, with bug fixes and component upgrades. Payara Platform Enterprise 6.5.0 comes with 10 bug fixes and a component upgrade. Payara Platform Community 6.2023.8 also comes with 10 bug fixes and 1 improvement.
In this new guide we look at how to improve cloud native, Jakarta EE application performance using the JCache.
JCache, or Java Caching API, is the standard cache API on the Java Platform. It is developed under
Java Specification Request (JSR) 107. JCache, similar to other Java APIs, comprises a set of core
interfaces organised under the javax.cache package. In this guide, we talk you through these interfaces and how you can get started with JCache, with code examples.
Payara Cloud is our fully-managed cloud native application runtime.
Unlike building an application server deployment on a Cloud Infrastructure as a Service or on raw Kubernetes, Payara Cloud takes care of provisioning infrastructure, installation, configuration, deployment and scaling of your application. Any web application following the Jakarta Web Profile specification can be uploaded and it will run in a containerized Payara Micro instance.
In this webinar Jakarta EE experts Otavio Santana (Java Champion & Software Engineer) and Luqman Saeed (Payara Tech Writer) explore the power of Payara and Microservices to develop ultrafast applications, diving into live coding with Jakarta EE and MicroProfile, leveraging the latest specifications, such as Jakarta Data and Jakarta NoSQL.
Additionally, they showcase the seamless integration of these technologies with the Microstream database, enabling lightning-fast persistence for your applications. Whether you are a seasoned developer or new to these technologies, this session will provide valuable insights and practical examples to accelerate your application development.
In this recorded webinar we explore how Payara Monitoring Console helps you streamline your Jakarta EE and MicroProfile application monitoring, troubleshooting, and management. Discover how the Payara Monitoring Console streamlines monitoring workflows, improves application performance, and enables faster incident response for your organisation.
Upcoming Java 21 brings a bunch of new features, including very interesting progress in concurrency. There are two main improvements – virtual threads and structured concurrency.
In this article, we discuss incoming usage of these enhancements inJakarta EE (formerly Java EE, now an open source project maintained by the Eclipse Foundation), a set of specifications that enables the worldwide community of Java developers to work on cloud native Java enterprise applications. Jakarta Concurrency is the concrete specification describing the expected behaviour.
The support in Jakarta EE is currently under development, details may change in the final implementation.
