Java

Join this session to gain an understanding where Jakarta EE is heading and how customers and communities can help drive the future of enterprise Java.

The past nine weeks of blog posts have introduced, explained, and demonstrated some of the many features of the Istio service mesh when combined it is with Red Hat OpenShift and Kubernetes. This, the final post in this series, is a recap.

The Eclipse MicroProfile project is moving fast with four releases and eight subspecs having at least two implementations each. This post provides an overview of MicroProfile 1.3, which was released on September 30th, and helps you to get started with the specification.

In this article I will explain how to externalized the HTTP session of a JEE application in an xPaaS environment, using JBoss EAP and JBoss Data Grid. I will describe the steps needed to easily build the solution and the key points related to it.

Using Istio with Red Hat OpenShift and Kubernetes makes life with microservices easier. But what if you want your microservice to talk to another service that is outside of your OpenShift/Kubernetes/pods environment? Enter Istio Egress.

A new release stream of Red Hat JBoss Enterprise Application Platform is now available: JBoss EAP continuous delivery (JBoss EAP CD). JBoss EAP CD provides rapid incremental releases of new JBoss EAP capabilities approximately every quarter and is delivered only in Red Hat OpenShift image format.

This is part 3 in a series on a journey to peek inside life in a Red Hat Open Innovation Labs residency. This is the top-tier experience for any customer, exposing them to open collaboration, open technologies, and fast agile application delivery methods. This post covers delivery week, known as Demo Day.

This is part eight of a ten-week series and covers using the Canary Deployment pattern to ease code into production. Istio makes this easy while giving you several good options for intelligent routing. And you can do it all without changing your source code.

Jakarta EE is officially out! The number of Java developers globally is estimated at over 14 million. The Java EE market is estimated at a high multi-billion Dollar value to the industry.

In the last post, we saw how Eclipse Vert.x can interact with a database. To tame the asynchronous nature of Vert.x, we used Future objects. In this post, we are going to see another way to manage asynchronous code: reactive programming. We will see how Vert.x combined with Reactive eXtensions gives you superpowers.

Testing software is challenging and very important. Testing for correctness is one thing, but testing for failures in network reliability is quite another task. This article will demonstrate how Istio makes this oh so easy.

In this post we are going to see how we can use JDBC in an Eclipse Vert.x application, and this, using the asynchronous API provided by the vertx-jdbc-client.

In this article, we will discuss using the Apache Camel-ZooKeeper component, and how we can set up a fail-over scenario for Apache Camel routes. While working in a clustered environment, situations arise where a user wants to have a backup route which will become active only when the master route stops working.

Istio brings tracing and monitoring to your system with very little effort, helping you keep things humming. This article covers Istio Tracing & Monitoring: Where are you are and how fast are you going?

This post is part of the Introduction to Eclipse Vert.x series. In the last post, we saw how this application became configurable and how we can use a random port in a test. Let’s go a bit further this time and develop a CRUD-ish / REST-ish application.

This article covers how to deploy a spring boot app which interacts with mysql in an OpenShift Environment. We might have a requirement where we have to migrate our Spring Boot standalone project to OpenShift environment or we might have to create Docker images.

The phrase "Failure is not an option" is tossed about with much bravado, with Istio Circuit Breaker. But the fact remains, things eventually fail. Everything. How, then, do you handle the inevitable failure of your microservices? This article will show you how.

In this post, we are going to enhance our Eclipse Vert.x application we created in the previous post to support external configuration, and then show how to deal with different configuration sources.

This series takes the reader on a journey, taking a peek inside an Open Innovation Labs Residency. A top tier experience for any customer, a residency exposes them to open collaboration, open technologies, and fast agile application delivery methods.

This is week three of a ten-week series about Istio, kubernetes and OpenShift. The series started with an introduction to Istio, and this week covers Istio Circuit Breaker: How To Handle (Pool) Ejection.

Red Hat Decision Manager 7 has been recently released. Decision Manager 7 is the successor of Red Hat JBoss BRMS, our business rules and decision management platform. In this post we will have a look at the main new features of the platform and we will provide instructions on how to get started

Red Hat JBoss® BPM Suite and Red Hat Decision Manager (formerly Red Hat JBoss BRMS) both use an artifact packaging known as a "KJAR", or knowledge artifact, since version 6. This article will review what is this file type and what separates it from a standard JAR file.
