Encryption of the data stored within the data grid of Hazelcast (the technology underpinning our deployment groups and clustering in Payara Platform 5) has until now required a Hazelcast Enterprise subscription (see Payara Scales). While this remains an option for those who would like the additional features it provides (such as WAN replication), we’ve begun introducing this particular feature into Payara Server itself to provide it to you without needing an additional subscription.

In order for a web application to run, it must be first deployed on an application server such as Payara Server. Deployment in the context of web applications is the act of installing the application on a server. It allows requests to be handled and so on. This guide will provide you with a few different ways to get your application running.

In Payara Platform 5.194 we introduced the monitoring console. The upcoming 5.201 release now offers numerous improvements and additions. We continued to followed our vision of a monitoring tool that users can configure to their needs, ranging from new tools such as watches and alerts, to new colour themes and settings users can tweak to match their individual preferences.

Dockerとは? DockerとPayara Server/Payara Microを一緒に使うには?

The transition of Java EE to the Eclipse Foundation is now complete with the release of the Jakarta EE 8 Platform Specification and the compatible implementations, including Payara Server. The release plan for Jakarta EE 9 is also approved, and will move all the Java EE APIs to the jakarta namespace - providing a future platform for Jakarta EE 10 and beyond.

One of the performance metrics that are frequently compared  by developers are startup times. Payara Server is designed to be manageable at runtime, with a central management server (DAS - domain administration server) and multiple instances, and as such is not optimized for extremely fast startup time. Payara Micro on the other hand, is optimized to run predefined workloads with a stable configuration at runtime, and is therefore a better fit for for comparing start up time metrics.

In this blog, let's take a look at how you can configure Payara Micro for fast startup time by utilizing the class data sharing feature of Eclipse OpenJ9.

With Spring Boot you can create an executable JAR file or a WAR file that can be run on a server. The latter option can also be used with Payara Micro. This blog shows you the different steps in creating and running such an application.

The approval of the Jakarta EE 9 Release Plan is a great milestone for the Jakarta EE project and a stepping stone towards the evolution of Jakarta EE into a project that meets the community's needs and wants. View the approved Jakarta EE 9 Release Plan here.
