This article shows you how to install Red Hat JBoss Enterprise Application Platform (JBoss EAP) XP 2.0.0 GA with support for Eclipse MicroProfile. Once you’ve enabled Eclipse MicroProfile, you will be able to use its quickstart examples to start developing your own MicroProfile applications with Red Hat CodeReady Studio. In this demonstration, you’ll learn two ways to build and run the MicroProfile Config quickstart application.

Welcome to the final installment in this three-part series about using Ansible Collection for JCliff to manage WildFly or Red Hat JBoss Enterprise Application Platform (JBoss EAP) instances. Previously, we’ve discussed installing and configuring the JCliff Ansible collection and using its basic features. In this article, we discuss advanced options available with the project’s latest release. Without further ado, let’s dive in!

Data is a critical business application component, but ensuring consistent, reliable data access can be challenging. Adding distributed services and high availability to your application requirements makes data access even more complicated. You can now use Oracle’s Universal Connection Pool (UCP) together with Oracle Real Application Clusters (RAC) and Red Hat JBoss Enterprise Application Platform (JBoss EAP) 7.3. This article introduces connection pooling with Oracle Universal Connection Pool and demonstrates how to integrate UCP with an Oracle RAC database in a JBoss EAP 7.3 deployment.

Welcome to the second part of this series introducing Ansible collection for JCliff. This new extension is designed for fine-tuning WildFly or Red Hat JBoss Enterprise Application Platform (JBoss EAP) configurations using Ansible. In Part 1, we installed JCliff and its Ansible collection and prepared our environment. We set up a minimal, working playbook for installing JCliff on the target system. In this article, we will focus on configuring a few of our WildFly server’s subsystems.

This three-part series guides you through using Ansible to fine-tune a WildFly or Red Hat JBoss Enterprise Application Platform (JBoss EAP) server configuration. We will use the most recently released version of the Ansible collection for JCliff to extend Ansible’s capabilities. The JCliff collection supports configuring several of the application server subsystems directly from Ansible.
In Part 1, we will mostly focus on the groundwork and discuss all the steps required to be able to use JCliff within Ansible. Once properly installed, we’ll use JCliff to configure WildFly’s
system_props subsystem, which lets us declare system variables in WildFly’s server configuration. Once we have that foundation in place, we’ll begin exploring more interesting configurations in Part 2 and Part 3.
Note: See the Ansible documentation for more about Ansible collections.

Based on Eclipse Che, Red Hat CodeReady Workspaces (CRW) is a Red Hat OpenShift-native developer environment that supports cloud-native development. CodeReady Workspaces 2.3 is now available. For this release, we focused on improving CRW’s configuration options, updating to the latest versions of IDE plugins, and adding new devfiles.
CodeReady Workspaces 2.3 is available on:

This article introduces a way to build and manage clustered environments using subclusters in a domain-mode installation of Red Hat JBoss Enterprise Application Platform (JBoss EAP). I assume that readers are familiar with JBoss EAP and the Apache HTTP Server (HTTPD)
mod_cluster module. I introduce the load balancing group configuration for that module.

If you are new to OpenShift, then you might want to install Apache Tomcat on top of it for simpler experimentation. This article guides you through installing Apache Tomcat from a Docker image and then using it to deploy a Java web app on Red Hat OpenShift. I also show you how to access the Tomcat management console on OpenShift.
To follow the examples, you must have an OpenShift account. We will use the OpenShift command-line interface (CLI) for this demonstration, so be sure to install the CLI (
oc) before you begin.
A note about the sample application: You will need a Java web application to use for the deployment example. I am using the Sample Java Web Application from the OpenShift Demos GitHub repository. It is a simple application that is useful for understanding basic concepts. You may use the provided sample or choose your own application to work with.
