Start learning about Camel in these excerpts from the book Camel in Action by Claus Ibsen and Jonathan Anstey.

This Vert.x crash class will present how you can develop a simple application using Vert.x, how to test it, package it and run it. So you have a great start on the road to building an amazing system on top of Vert.x.

This article covers Istio Route Rules and telling Service Requests Where To Go. OpenShift and Kubernetes do a great job of working to make sure calls to your microservice are routed to the correct pods. What if, however, you want to customize the routing?

Read this article if you interested in an introduction to the concepts of process management (BPM); you want to learn how your business can leverage process driven application delivery; or you are looking for an easy to understand guide to mastering Red Hat JBoss BPM suite tooling.

This article will describe the main features of the MicroProfile Fault Tolerance specification and then demonstrate how it was implemented in WildFly Swarm, the Red Hat MicroProfile implementation.

Red Hatter, Eric D. Schabell, provides a step-by-step review of Red Hat JBoss BPM Suite, a powerful business process management system.

this is an introduction to Istio. Istio helps automate the developer time to implement a feature. The combination of code complexity and code heft (i.e. number of lines of code) can put a drag on an implementation. Istio is a better way.

This article shows how developers writing Java-based microservices can leverage the Eclipse Microprofile 1.2 specifications for Configuration and Health checks to take advantage of the management capabilities provided by Red Hat OpenShift and Kubernetes.

demonstrating how to use a custom version of Hibernate (Hibernate ORM and Hibernate Search) on a WildFly Swarm Java application.

Red Hat JBoss Fuse 7.0 technical preview three is out today! On the pathway to become one of the best cloud-native integration platforms, JBoss Fuse gives developers the freedom to choose how they want to develop the integration solution, where they want to deploy it.

Using Byteman to Find Out Why the TimeZone Changed on a Java App Server. This article is about a real problem I faced where the timezone on a Java application server (in my case it was JBoss) changed unexpectedly during the run time of the server.

all about scheduling speakers and rooms for Voxxed Days Zurich 2018 using the tool: OptaPlanner. This involves Reading, evaluating, discussing, and selecting from the 200+ proposals that arrive every year is a long and challenging process.

A user guide of Java Class Metadata. I presented a talk last week in the Free Java Room at FOSDEM 2018 on the subject of Java Class Metadata, explaining what it is, why it helps to know about it, what you might do to measure it, and reduce the impact of it's footprint on  your Java application.

This post provides an overview of the APIs and specifications in the Eclipse Microprofile 1.2 specification for Java. We connect these specifications and APIs with their architectural purpose for building robust cloud-native applications and microservices.

A DevNation Live session - MicroProfile - Microservices with Java EE

Eclipse Vert.x is increasingly popular for writing reactive applications on the JVM. Testing code with asynchronous operations is more challenging than it seems. JUnit 5 is a rewrite of the famous Java testing framework that brings new interesting features. Testing using JUnit 5 is now available in Vert.x

Applications running on OpenShift get their logs automatically aggregated to provide very valuable information on their state and health during tests and in production. In this blog I am covering a few points that may help you with bringing your logs from raw material to a more valuable product.

When using Byteman scripts for tracing and debugging with Red Hat JBoss Fuse and AMQ, learn how to use Java helper classes with for advanced options, such as viewing or modifying arguments, and utilizing 'java.util.logging' to inject messages into the existing logs.

Accelerate Application Development With Red Hat JBoss Middleware And Microsoft Azure. The role of applications has changed dramatically. a well-developed, well-timed application can disrupt an entire industry. Just take a look at the hotel, taxi, and movie rental industries respectively.

you have a remote Enterprise JavaBeans (EJB) application where the EJB client is a service pack (SP) application in a Security Assertion Markup Language (SAML) architecture. You would like your remote EJB to be authenticated using same assertion which was used for SP.

The purpose of the article is to describe how to use Red Hat JBoss Developer Studio or JBoss Tools together with the OpenShift online starter platform.

In a production or customer environment it is not always possible to identify issues by looking at logs or setting up a remote debugging using IDE. Often the issues are specific to the environment and can't be reproduced. having byteman scripts can help in identifying issues without actual code changes.

Get an in-depth tour of OpenShift®, the container-based software deployment and management platform from Red Hat® that provides a secure multitenant environment for the enterprise. This practical guide describes in detail how OpenShift, building on Kubernetes, enables you to automate the way you create, ship, and run applications in a containerized environment.
