Introduction

The asadmin Command Line Interface (CLI) is a mean of controlling Payara Server from the command line (or terminal, if you prefer). It allows you to start, stop or edit the server in a number of ways. While to some the administration console is the go-to for any administration that needs to be done, the CLI can be a potentially quicker and easier way of performing any administration tasks, particularly when dealing with headless servers, i.e. a server without a GUI.  

When dealing with complex distributed systems, decoupled, asynchronous communications may be more suited to support the exchange of information between different parts of a system, or even completely different systems. In effect, this decoupling makes it possible for different parts of a system to interact without being directly connected, enhancing scalability and fault tolerance. It is possible to set up such communications through a messaging platform like Apache Kafka and design highly scalable applications.

Our new eBook - available to download here - discusses how to use Apache Kafka for Jakarta EE Platforms that use Payara Server. 

Ahoy, Payara Community! Here's an overview of our fresh catch for March, where we've reeled in our favorite bits from the depths for you to enjoy and power up your Jakarta EE applications!

Greetings Payara Community! Enjoy our favourite bits we gathered in our monthly catch for January.

The Payara Platform is a comprehensive ecosystem designed to meet the diverse needs of today's enterprise Java developers like you, offering robust solutions for Jakarta EE applications. The Platform is split into two main products, namely Payara Server and Payara Micro.

New to Payara Platform? Check out these two quick videos where we show you how to download and install Payara Server 6 & Payara Micro 6.

Sealed classes are a powerful feature introduced in Java 15 that allows developers to control the inheritance hierarchy of a class. In this blog, we will explore the concept of sealed classes in the context of Jakarta EE, a set of specifications for building enterprise applications in Java.

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.

Apache NetBeans is a popular IDE for Java development, offering a wide range of features for streamlining the development process. Payara Server, a robust and scalable option for deploying Jakarta EE applications, seamlessly integrates with Apache NetBeans. In this blog, we explore the seamless usage of Payara Platform 6 within Apache NetBeans, highlighting the benefits and demonstrating how it enhances your development workflow. Whether you're starting a new project or working with an existing app, this guide helps you leverage the power of Payara Server in your development process. Follow the steps in this blog to set up Apache NetBeans to use Payara Server for running your web apps.

Why is software testing so important? Firstly, because we are all susceptible to making mistakes.
Secondly, because the sooner we find bugs and fix them, the cheaper the fix!
