You probably know that a DAS, or Domain Administration Server is an instance of Payara Server, but you probably don't know that from the console of Payara Server you can now manage an instance of Payara Micro directly from the DAS. This means from within the admin console you can send your asadmin commands directly to any Payara Micro instance within your cluster.

 

We recently held a webinar hosted by myself, Arjan Tijms and Ondrej Mihalyi based on exploring and demonstrating the latest features and updates in the 184 release. This included:

For a long time, the Java EE security system has had a quite cool, but   woefully underused, feature; pluggable authorization modules. The authorization modules are provided by a specification called Java Authorization Contract for Containers, aka  JACC. 

 

Azure Container Instances allow you to rapidly deploy containers to the Microsoft Azure cloud without having to manage virtual machines and the corresponding infrastructure. Container Instances can be used to rapidly deploy Java EE and MicroProfile applications using Payara Micro as the underlying platform for your Cloud Native applications.

The Payara Platform is perfect for deploying Jakarta EE and MicroProfile applications on Microsoft Azure. One rapid option for deploying on Azure is to use Azure Application Services, especially Web App for Containers. The WebApp for Containers service allows you to rapidly deploy production Payara Micro applications onto Azure in seconds, allowing both rapid horizontal and vertical scaling on demand.

In the previous guide, we’ve seen how we can configure the Payara Platform to connect to a database and use the datasource from an application. This guide walks you through the process of building an application to store and retrieve data from the database.

Introduction

OpenID Connect is a security mechanism for an application to contact an identity service, verify the identity of the End-User based, and obtain End-User information using REST API's in a secure way.

Watch this quick video to learn how to install the open (Java Development Kit) JDK 8 by Azul Systems called Zulu. A JDK is needed to write Java apps.  We'll take you step by step through the process of checking to make sure you don't already have a JDK installed through to installation of Zulu.

A REST Service in Java EE can be created using JAX-RS. The contents of such service can be consumed using ordinary HTTP requests to a URL. URLs are typically kept simple and have a logical pattern, so it's easy to type them manually in e.g. a browser. This is different from SOAP, which essentially uses HTTP as well, but is designed to be rather complex and therefor making it not so easy to quickly test something in a browser.
