Welcome to a new installment of the JBoss Weekly Editorial! (Which is now released every two weeks, but let’s not get sidetrack by that). The biggest news is for sure IBM and Mark Little have commented on that on his blog, but don’t worry, there is also plenty of more technical or community-related news for you!

 

Big Purple

 

The times, they are changing ! As you must be aware by now, IBM bought Red Hat, as announced a few months ago. The purchase being finalized, there is now an ocean of questions (and, to be honest, opportunities for collaboration) arising. I wish we could have all the answers to your question, but, hopefully, this blog entry from Mark Little, we still answer some for you.

 

Techbytes

 

A few interesting articles have been released in the past week. First is about Drools & jBPM: Kogito, ergo Rules — Part 1: Bringing Drools Further . It is to be noted that the Kogito project aims at providing the best possible cloud integration to both Drools & jPBM, so if you have any interest in both topics, you should certainly check this one out!

 

The next one is very exciting. I've been a fan of JGroups since I've been introduced to the frameworks back in 2005 (gosh, I'm not getting younger).  It has been the backbone of the JBoss Clustering solution for decades now, but the framework was also often leverage in cutting project. And now that Bela Ban released this article on Compiling JGroups to native code with Quarkus/GraalVM, I'm sure the possibilities unlocked with both Quarkus and JGroups are going to be endless!

 

Still not enough? Still craving for more technological babble to impress your friends at dinner parties? Well, then take a look at this one: Debezium Apache Kafka connectors for Change Data Capture (CDC).

 

Java Tooling

Despite the decade-long rumors of Java upcoming death, the corpse still appears to be moving and thriving. The zombie language even appears to learn new tricks or rather get new swagger, as illustrated by the 17-million downloads of Visual Studio Code Java extension.

But rest assure, if you are still not feeling comfortable coding Java in Visual Code, you can get started with Red Hat CodeReady Studio 12.12.0.GA and JBoss Tools 4.12.0.Final for Eclipse.

 

Evangelist's Corner

 

For the summer (well, summer in the northern hemisphere), Eric D. Schabell re-released an updated version of his classic 3 More Pitfalls Everyone Should Avoid with Hybrid Multicloud (slides). If you missed it the last time around, you have another chance to check it out! He also released a new Beginners Guide on "Building an Online Retail Web Shop Workshop (Domain Model)".

Releases, releases, releases... Infinispan version!

 

The Infinispan project has been quite busy in the last days. They released a new version of the core project, along with a new version of the Infinispan Operator. Take a look!

Welcome to another edition of the JBoss Editorial, join me in another trip through the JBoss Communities as we search for exciting developments and news from our projects.

 

Apache Kafka Streaming with Red Hat AMQ Streams

 

In a two part series discussing the development of an Apache Kafka Streams application, Adam walks us through all of the necessary steps to create an application using Red Hat AMQ Streams and the Streams Domain Specific Language.  The first article in the series discusses the creation of a simple containerised example application which can be used as the building block for the discussion within the second article when Adam shows how to create a more comprehensive pipeline using real world data, the Kafka Stream DSL and the Vertx Kafka client to compose an application which will process the events and visualise the outcome via a javascript dashboard.

 

Transactions, Object Stores and Expiry Scanners

 

Transactions are a feature which ensure applications behave correctly in the face of failures, handling the management of the resources enlisted in the transaction and coordinating their responses to achieve a consistent outcome.  Transactions are conceptually simple to use, however as with swans gracefully swimming the real work takes place under the surface where it's largely invisible to the majority of us.  The Narayana transaction manager is responsible for providing this feature within the Red Hat Middleware products but how does it work?  What is an Object Store?  How are failures handled?  How does recovery work?  How does expiry work?  Let's find out from Ondra ...

 

Monitoring jBPM using Prometheus and Grafana

 

The jBPM 7.21.0.Final release introduced a new Prometheus Kie Server Extension for publishing metrics related to the server and its runtime behaviour, enabling a deeper understanding of the server and the business processes.  In an article on the subject Cristiano explains how to enable  this extension, includes a short video showing it in action and provides a docker compose configuration for creating a local setup which you can use as a playground for exploring the integration with these tools.

 

Securing Web Applications using Elytron

 

Web applications deployed to WildFly can take advantage of the Elytron integration to require clients authenticate using X.509 certificates, this integration allows the server to not only verify the identity of the client but also use this identity to drive authorization within the application.  In a blog post on the subject Farah takes us through the steps to generate certificates, configure the server for CLIENT_CERT with mutual authentication and finally demonstrate the feature using a sample application.

 

Elytron also provides a credential store API/SPI which applications can use to manage the secure storage of credentials, check out Darran's blog post for more details and an example application showing how it can be used.

 

Camel Core Decomposition

 

The Camel team are very busy working towards the Apache Camel 3 release, with much work already having been done and three milestone releases under their belt.  One of the biggest efforts underway within milestone 4 is the decomposition of camel-core into smaller modules to allow applications to choose only those components they will need and help to minimise the size of the transitive dependency graph.

 

Customising the WildFly Console Title

 

The release of Hal 3.2.0, part of WildFly 17, now includes an option for customising the title of your console tab allowing you to better differentiate between different servers should you have multiple tabs open.  The new feature relies on two attributes within the management model, the name of the server and the organization it belongs to, which can be composed into the title through the settings page of the console.

 

Red Hat Decision Manager Workshop Refresh

 

With the release of Red Hat Decision Manager 7.3 Eric Schabell has been revisiting his free online workshop to align its content with the new release.  Eric has now updated the first two labs in the workshop covering the installation and the creation of a new project to be used within subsequent labs.

 

JBoss Out and About

 

Eric Schabell will be presenting at DevConf.us in Boston, an annual, free technology conference sponsored by Red Hat which will take place from August 17th to 19th.  Eric has three presentations accepted including "How to Jump Start Your Career in Open Source", "3 Pitfalls Everyone Ignores with Microservices" and "7 Steps to Expanding Your AppDev Toolbox".  Eric will also be in Raleigh, North Carolina for DevOps Days Raleigh which is taking place from October 1st to 2nd, Eric will be presenting "DevOps Heroes - Adding Automation Integration to your Toolbox"
