Este artículo continúa nuestra serie de blogs de introducción para configurar un cluster con Payara Server, continuando desde nuestro último articulo donde configuramos un balanceador de carga para nuestro cluster.

As a Java EE developer, I sometimes envy how fast it’s possible to see the result of a code change in a running application with interpreted languages like PHP or JavaScript. With Java, it’s always necessary to rebuild the source code in bytecode, which can be then safely updated only by restarting the whole application. And all developers know that restoring the desired state of the application after a fresh restart takes time and is tedious.

Have you ever wondered how you can improve the performance of your applications under high load? You've probably heard that reactive design can help meet better response time and make your applications more flexible. In this presentation, I will show that you don’t need to rewrite your Java EE applications from scratch to achieve that!

Following up from the first part of the Security Auditing  article, where we covered the audit logging,  in this part we will focus on creating a custom audit module.

Security is always a concern you must have when implementing applications that will run in production environments. Both the JVM and Payara Server have a strong tool set of security implementations for most use cases in the industry, so you won’t have to worry about implementing your own security measures from scratch.

The previous part of this blog showed how to take a thread dump of Payara Server. This part will go through reading these thread dumps, particularly in regard to identifying deadlocks.

Thread dumps are a useful tool for debugging an application that's running slowly, or is otherwise causing problems. A thread dump is a snapshot of what each running thread is doing at a particular moment. It allows you to see if a thread is running, waiting, or stalling. This two-part guide will show you how to take a thread dump of Payara Server, and how to get useful information from it.

Throughout the last year, the Payara team were tracking all the important activities related to Java and Java EE. We attended many conferences, actively participated in lots of community activities, and we helped to found a completely new MicroProfile initiative, with the aim to facilitate innovation in the enterprise Java space.

With this article I'd like to look back at 2016 to share my impressions from the past year with you and outline what we at Payara expect to happen in the Java world in 2017.

One of the biggest challenges when developing applications for the web is understanding how applications need to be fine-tuned when releasing them into a production environment. This is no exception for Java Enterprise applications deployed on Payara Server.

The new Java Magazine is out now, featuring a lot of useful articles about enterprise Java - not so much Java EE as a platform, but individual services that can be useful as part of a larger solution. See below for an introduction to my article on Custom Servlet Authentication Using JASPIC, also featured in the magazine.
