Weekly Editorial

335 posts

Welcome to a post-Red Hat Summit JBoss Weekly Editorial! We just came back from Red Hat Summit 2019 in Boston. What a great week with some amazing news! Of course two big announcements that came out of Summit this year are Red Hat Enterprise Linux 8 and OpenShift 4. Great things coming out of Red Hat these days!

All of that being said, there have been some other interesting happenings this week since Summit. There’s only one release, mostly due to Summit, but we will go over blogs and some great things from the community. That release was JBossWS, see the release post for more information.

Blogs

A number of blogs came out over the past couple of weeks. Check out the blogs featured below!

OptaPlanner

If you weren’t at Summit, or missed the Thursday morning general session, you can see the recording below.

 

Thursday morning general session - May 9 - Red Hat Summit 2019 - YouTube

 

A large part of the demo was handled with OptaPlanner. Geoffrey De Smet has done a series of blog posts detailing its use in the demo:

Geoffrey has some great breakdowns about how OptaPlanner was used, things they learned, and some code as well!

Eric Schabell

Eric Schabell gave a talk at Summit titled "3 Pitfalls Everyone Should Avoid with Microservices." In his blog he details the talk a bit more and gives gives you a link to see the slides.

Eric also has a blog post about setting up integration tooling for CodeReady Studio 12. This will be an ongoing series from Eric. Look for more posts details more information about CodeReady Studio 12.

Update on Eclipse Jakarta EE Rights to Java Trademarks

The big news this week was around an update to Jakarta EE's rights to use Java trademarks. You can read the announcement here by Mike Milinkovich. Essentially, it's not been possible for Oracle and the Eclipse Foundation to come to an agreement on a seamless transition for beyond Jakarta EE 8. As a result the Jakarta EE community will not be able to modify the javax namespace. You can read Mark Little's views of this announcement here. Mark later followed up (here and here) with some of his personal views on the announcement and provided some insight on the paths he sees going forward.

Hands on Labs at Red Hat Summit

Red Hat Summit is being held next week in Boston (May 7th - 9th). Eric Schabell will be hosting two hands on lab sessions. The first covers the new Red Hat Enterprise Linux 8 and the second covers IT automation and management.

 

JTA and CDI integration

The 5.9.5.Final release of Narayana comes with several CDI functionality enhancements. In this blogpost Ondra Chaloupka introduces these changes whilst focusing on the JTA and CDI integration.

 

Keycloak Releases and Versioning

We are aiming to achieve a continuous delivery model with Keycloak. By that we mean it should be seamless to upgrade between Keycloak releases and to keep up to date with the latest release. Read this blog post by Stian Thorgersen to learn about what will change.

 

What is Apache Camel K?

It's "A lightweight integration platform born on Kubernetes, with serverless superpowers". Watch a short video here to learn more.

 

Releases

With something things happening lately, we have (again) missed an editorial two weeks ago! All our apology about that, but this one will catch you up if you have missed anything. No surprise, only a few weeks after its releases, Quarkus, and its beloved friend, GraalVM, are still the center of the attention! (as it should be!!!)

The smoking gun of a newborn star

Quarkus and GraalVM

With its recent releases, Quarkus is certainly a trending item! Especially when we see how far the project can go with coupled with GraalVM. And this potential is certainly leading to some exciting experiments like: Adventures in GraalVM: polyglot Camel (k) native routes with Quarkus, or Towards a Polyglot Drools on GraalVM (with Bonus Tech-Lead Prank)!

 

Quarkus being a very new and innovative context of execution for an application, it is to be expected for people to try to migrate their own application. If you plan to do so, this article on Migrating Java applications to Quarkus: Lessons learned is a “must-read”! After that, you may want to take a look at this one From zero to Quarkus and Knative: The easy way. With those two articles, you should be set to go even further in your exploration of Quarkus!

 

Note: If you happen to be able to read french, note that I will also release an article on Quarkus in next month’s issue of GNU/Linux Magazine France.

Retrospective on the bmpNEXT

If you are interested in rules engines and processes manager, but you happen to had no chance to join the bpmNEXT conference last week, here a few impressions for you (along with some teasing about our upcoming Red Hat Summit):

Still relating to rules, especially, in this case, drools, we also mentioned above, in the section about Quarkus, this quite cool article  Drools & jBPM: drools.js: Towards a Polyglot Drools on GraalVM (with Bonus Tech-Lead Prank) ! We’ve repeated here so to be sure you don’t miss it !

Evangelist's Corner

As always, our own Eric D. Schabell has been quite prolific, especially has he has joined several conferences:

On top of this material, he also took the time to promote upcoming labs at the Red Hat Summit 2019 (7–9 May):

Last, but certainly not the least, don’t forget to catch up with the Infinispan project, if you have the opportunity, on the Infinispan on tour, March-April 2019!

Techbytes

This editorial is already quite a mouthful, but maybe you can stomach a bit more? If so, take a look the following entries:

Releases, releases, releases…

As always, the JBoss community can go two weeks without a fair amount of new releases. Among the most notable, there is, of course, a new minor version of Quarkus, but also a first major released of Keycloak!

Décaf’

 

After digesting that much Java technologies, you are maybe craving for something else, right? Well, let us offer you a nice Introduction to Kubernetes (From container to containers), this ought to be a nice change of pace!

 

That's all for this week's edition of the Editorial, please join us next time as we continue our journey through the JBoss Communities in search of interesting articles and news. 



Welcome to another JBoss Weekly Editorial as we prepare for the end of March! We have a number of releases and blogs posts to highlight, so let’s get to it.

 

Blogs

Christina Lin has a blog detailing which she believes are eight ideas that lead to "catastrophic cloud native microservice" deployments.If you are working with microservices, or are thinking about it, this blog is certainly worth a look.

 

Eric Schabell has written a couple of pieces on integration and has a follow-up lab to better explain the points of integration and automation.

 

Lastly, Brain Stansberry detailed the Wildfly 17 release roadmap over on the Wildfly site.

 

Great stuff is happening within Red Hat! Stay tuned for even more as the year progresses!

Thank you for joining us for another edition of the JBoss Weekly Editorial! We have some great news, blogs, and releases this week! Read further down for more information.

 

Quarkus

 

Quarkus: Supersonic Subatomic Java. As the website describes it: A Kubernetes Native Java stack tailored for GraalVM & OpenJDK HotSpot, crafted from the best of breed Java libraries and standards.

 

Quarkus was released earlier this week with great fanfare! It’s been a nine month journey to get here, but we’re all very excited about what this will enable developers to do. Gone now are the days of tests taking long enough for you to check your Facebook page, hot re-deploys, expensive memory usage, long deploy times.

 

Would you be interested in a REST & JPA application fully starting up in under a second and using less than 40MB of memory? Would you like to save and refresh your web browser to see changes like the dynamic language devs do?

 

You want integration? Quarkus integrates with Apache Camel, Hibernate, Apache Kafka, Jaeger, Vertx, and others! Be sure to buckle in because we’re just getting started.

Read about Quarkus from Emmanuel Bernard, Mark Little, or simply head over to the Quarkus website to learn more! Your productivity will thank you.

New Releases

 

In addition to Quarkus, there have been a number of new releases over the past couple of weeks:

Blogs

 

Security features continue to improve in Wildfly with both the release of Wildfly 16 and Elytron 1.8.0. You can read more about some of the new features and improvements at Darran Lofthouse’s blog.

 

Stain Thorgersen has blogged about WebAuthn and support coming soon to Keycloak.

 

The Infinispan team blogged about releases around the trifecta of cache store releases Cassandra, Cloud, and MongoDB Cache Stores. There’s also a blog by the Inifinspan team talking about the Subatomic Infinispan Client.

Business Process Management News

Eric Schabell continues his "Modern Process Integration Tooling Workshop" series with parts four and five. These instalments focus on creating a business process. Eric will be delivering the full workshop on the 7th of March in Edinburgh for JBUG:Scotland. See here for more details. Whilst  working on the workshop, Visual Studio users can try the jBPM plugin for quickly viewing process diagrams.

 

In other news JHipster users can now generate jBPM Business apps with it. See here for more details.

Hibernate Community Newsletter 04/2019

If your a developer using Hibernate, you'll likely find this roundup of the latest Hibernate news of interest.

 

Monitor active management operations and detect non-progressing operations

In this post Harald Pehl explains how to monitor management operations in the WildFly application server. This hands-on post walks you through how to list and cancel active management operations as well as detecting those that are failing to progress.

 

 

New Releases

Welcome to the first edition of the JBoss Editorial following the recent Chinese New Year, another trip through our communities as we search for exciting pieces of news from the projects.

 

IoT Edge Development and Deployment with Containers

 

In the first part of a two part series Alessandro takes us on a journey exploring how we can use a Platform as a Service such as OpenShift for developing and distributing IoT edge applications, taking advantage of a container's portability.  In the second part Alessandro extends the demo from the first part to target applications running on alternative architectures such as ARM 64.

 

Enabling CORS in jBPM Business Applications

 

When generating jBPM Business Applications you will discover the applications will have CORS disabled by default however this behaviour will change in the the next jBPM community release when CORS will be enabled by default.  In the meantime if you want to enable CORS in the applications you are currently generating then Tihomir demonstrates how this can be achieved.

 

Eric's Modern Process Integration Tooling Workshop

 

Eric has been updating his free online rules and process automation workshop to the latest versions, updating JBoss BRMS to Red Hat Decision Manager and JBoss BPM Suite to Red hat process Automation Manager.  The entire workshop has been updated to use Decision manager 7.2, starting with Lab 1 covering installation and Lab 3 covering the creation of Domain Models.

 

Kubernetes and Application Servers

 

In the final article of his series comparing and contrasting Kubernetes and Application Servers, Ken poses some questions to help you evaluate whether you should be choosing a Kubernetes solution, an Application Server or an alternative such as Thorntail.

 

Integrating Keycloak with Let's Encrypt

 

When testing or deploying a proof of concept using Keycloak it is common practice to choose a self signed certificate however this will raise certificate warning errors from your browser.  This is not the only option thanks to Certification Authorities such as Let's Encrypt, enabling the automated issuing of certificates trusted by all major certificate root programs.  If you wish to try this with Red Hat SSO then give it a try with a developer subscription.

 

Podman and Kubernetes

 

The Podman team have been playing around with the idea of transitioning local pod deployments to kubernetes and enabling these generated kubernetes configurations to be replayed within a local environment.  To demonstrate these capabilities Brent has written an article showing how to move a simple nginx deployment to kubernetes and then follows with a more complex example being moved to kubernetes and back to local deployments.

 

Streamlining your JBoss EAP development environment with CodeReady Workspaces

 

In the second part of his series discussing how to streamline your JBoss EAP development with CodeReady Workspaces, Laurent continues his tutorial by showing how extend the workspace from his first article to include commands for building and running a JBoss EAP project, using this to deploy and debug the application and finally how to configure a factory to allow your work to be shared with others collaborating on your project.

 

Hacking on A-MQ Online

 

Christina was recently invited by the EnMasse team to hack on their new A-MQ Online platform, their self service messaging platform which allows an application developer/user to quickly spin up their own queues and topics.  Following the experience Christina wrote down her take on the basics and recorded a couple of videos describing A-MQ Online in more detail.

 

Developing Cloud Native Microservices using Apache Camel

 

Claus recently gave an hour long webinar where he demonstrated how to leverage the Enterprise Integration Patterns best practices within kubernetes through the development of Camel based microservices and the serverless capabilities if the upcoming Camel 3.0 release.  The webinar has already taken place however the recording is available through the on demand service.

 

Hibernate Community Newsletter

 

In Hibernate Community Newsletter 03/2019 we find articles discussing how to handle SQL reserved keywords for database identifiers such as table or column names, how to integrate JPA and Hibernate with Spring Boot, supporting the wide variety of column types in PostgreSQL, how to map one-to-one relationships and how to map many-to-many relationships with additional columns.

 

New Releases

 

 

That's all we have time for in this edition of the JBoss Editorial, join us again next time when we will take another trip through our communities in search of more news, articles and releases.

This new year has barely begun but the JBoss community is already running full steam ahead! But don’t worry, this editorial will catch you up in no time.

Fire

Wildfly has a new project lead!

 

Let's start by some rather important community news: WildFly Project Lead is now Brian Stansberry ! Willdfly is a crucial project for the JBoss community but we are very lucky to see Brian Stansberry taking the lead here. He has been working for years and the project and he is a perfect fit for the position.

 

 

January is the hear of Winter so it's only but fitting that the Hibernate community is quite active! First of all, the last weeks have seen quite a few interesting releases:

But there was quite a lot more happening at the same time! If you want to catch up, just browse the last two community newsletters they've released:

 

Evangelist's Corner

 

Our very own Eric D.Schabell appears to have decided to skip the winter holidays altogether and just keep blogging and posting like a machine! Look at all the material he released in the past weeks:

 

Techbytes

 

By now, you should be all catch up with the news so let's now dive into some more technical topic. First, let's take a look at Securing an embedded Jetty server using Elytron. Or maybe Using the Yeoman Camel-Project generator to jump start a project will be more up your alley? Eager for more? Well, look into Building Java 11 and Gradle containers for OpenShift ! At least, but not the least, Eclipse Che 7 is coming and this series of articles will make you want to try it for sure:

 

Total eclipse

 

As you can see, the winter holidays has not slowed down the releases within the JBoss community:

Decaf'

This editorial should contain enough "Java" to keep you up all night! So let's me conclude with something a bit less caffeinated, but that should still be quite interesting to most members of the JBoss community: Security Considerations for Container Runtimes.

 

 

That's all for this week's edition of the Editorial, please join us next time as we continue our journey through the JBoss Communities in search of interesting articles and news. 

All of us are getting ready for the Holiday Season, thank you for taking some time catching up with us this week! The past couple of weeks can be summed up in three words: Releases, jBPM, Integration! Let’s do a quick recap in that order.

 

jBPM

There were a number of blog posts in the jBPM realm over the past couple of weeks. They’ll make for some great reading and a good way to catch up on what’s going on in that space!

Integration

Lastly, we have a few blog posts dealing with integration:

 

Thanks again for sharing some time with us, see you next time!

The last editorial was focused on the "breaking news" of the day. Even if the dust has far from settled on this, it's time for us to get back to business as usual! Well, not really as usual, because we have a rather awesome announcement about .... SpringBoot!

 

SpringBoot

While technically more of a Red Hat news than a JBoss community one, it seems to very much deserved to be mentioned here: Announcing: Full Spring Boot support for Red Hat OpenShift Application Runtimes !!! I won't comment more but I will urge to take a look at the post!

 

Infinispan - on road to version 10!

 

The Infinispan project is getting close to release its next  major version and they have laid for us the road ahead: The road to Infinispan 10 (Alpha1)! This post is nice sum up of the coming new features and changes in the project. I highly recommend you take a look at it. And if you have not yet played with or experimented with Infinispan, maybe this Quick start Infinispan on Kubernetes would be a nice opportunity to do so. And if you have familiar with Infinispan, you certainly want to explore its usage on Kubernetes!

Tech Bytes

 

The headlines above are already plenty to digest. However, you might still be hungry for a tidbits of technical knowledge. We therefore selected a few things for you to nimble on:

 

Not done yet? Worry not, our own Eric D. Schabell has also plenty for you to fest on!

 

 

Releases, releases, releases...

While we are blogging, twitting and emailing, the developers of the JBoss Community are quietly working and more importantly.... Releasing!

 

That's all for this week's edition of the Editorial, please join us next time as we continue our journey through the JBoss Communities in search of interesting articles and news.

Welcome back! It has been a busy couple of weeks for us within Red Hat Middleware. Hot on the tails of Oracle CodeOne is Devoxx BE, followed shortly after by Devoxx MA!

 

Red Hat and IBM

We want to start things off with news you have probably heard, but if not, IBM and Red Hat have entered into an agreement where IBM will be purchasing Red Hat. You may have read various blogs, articles or news stories about the acquisition. We asked Mark Little, VP of Engineering here at Red Hat for some thoughts:

They say 24 hours is a long time in politics but maybe it applies to the technology sector too! Between the last time we published the editorial and now Red Hat has agreed to be acquired by IBM. As the public statements from IBM and Red Hat discuss, the deal won’t officially close until the second half of 2019 and until that happens both companies must remain operating as independent entities. There have also been strong statements from both sides that Red Hat will be a separate entity within IBM in order to preserve the benefits of acquiring such a leader in the open source space. At this stage though there are very few details that I or others can share publicly. However, and I’ve written about this in my personal blog, I feel quietly confident that this acquisition (more like a semi-merger) will be good for Red Hat, our communities and our customers, as well as IBM.

Thanks Mark!

Releases

Naturally, there have been a number of releases in the past couple of weeks. Here are some of the highlights:

Blogs

We’d also like to draw your attention to some blogs from the community:

Thank you everyone for being part of the wider Red Hat Middleware family!

Welcome to another edition of the JBoss Editorial, our regular trip through the JBoss communities in search of interesting developments.  In this week's edition we are largely focussing on jBPM with numerous articles being written by that community.

 

jBPM in Abundance

 

We start our jBPM fest with an article from Maciej demonstrating the sophisticated form builder available within the KIE Server, no longer restricted to the workbench, and provides support for rendering process forms, case forms and user task forms.  Maciej includes some screenshots from the sample projects as well as some screen casts showing this in action.

 

The next articles are primarily video, demonstrating how you can quickly create a dashboard to interact with your business processes and an early preview of the jBPM Case Modeller improvements.

 

Continuing the jBPM theme we take a look at which strategies your business process can adopt to introduce resiliency when interacting with services, dealing with exceptions raised by the service through the creation of a subprocess followed by a decision to complete, abort or retry the service task or to re-throw the exception to the caller of the task.

 

One of the strengths of jBPM is its ability to integrate your business processes with external services including third party integration services such as IFTTT, in our next article Tihmoir creates a demo showing how to use the IFTTT workitem to invoke an applet on the IFTTT platform, in this case launching Google Maps on your phone and sending you an SMS.

 

We end our tour of jBPM with an introduction to a new Tech Preview feature in Workbench 7.13.0.Final, the DMN Editor Preview.  The editor is disabled by default and still under development, however it is a simple task to enable the editor allowing you to then create and deploy a DMN model.

 

Introducing Camel K

 

The Apache Camel team have introduced a new project designed for serverless and microservice architectures, Apache Camel K (aka Kamel).  Kamel runs in a kubernetes environment, such as OpenShift, and makes use of the operator pattern to drive the deployment and execution of integration patterns expressed using the Camel DSL.

 

Integrating Third Party Identity Providers with 3scale API Management

 

With the release of 3scale API Management 2.3 it is now possible to directly integrate a third party, OIDC compliant identity provider, whereas in previous releases this task had been satisfied by using Red Hat Single Sign-On as the identity broker.  To demonstrate how this integration works Luca walks us through the integration of 3scale API with Management Oracle IDCS and Microsoft Azure Active Directory.

 

Using Keycloak to provide Single Sign-On

 

When securing websites one deployment configuration commonly used is to place a reverse proxy in front of the server providing the content and have the reverse proxy handle the interactions with an OpenID Connect server to perform authentication and authorisation.  To explain how this scenario can be deployed Siddhartha takes us through an example which uses Keycloak as the authorization server and NGINX as the reverse proxy.

 

Hibernate Community Newsletter

 

In Hibernate Community Newsletter 20/2018 you will find articles explaining several optimisations for speeding up batch processing, how to use the paging mechanism to retrieve only the information you need, how to use DTO projections with the Spring Data JPA to efficiently fetch read-only information, how to simplify data persistence using JPA and Hibernate and an explanation of Hibernate proxies and how the session load method works with the get and find methods.

 

Integrating Narayana and Agroal Connection Pool

 

Agroal is a database connection pool developed by Luis Barreiro, one of the performance engineers on the WildFly project, and is one of a number of pooling options which integrates smoothly with Narayana.  The combination can be used within a standalone application as well as through XA resources within the WildFly application server.

 

Using WildFly Elytron JASPI with Standalone Undertow

 

As part of the development efforts for WildFly 15 the Elytron team created an implementation of the servlet profile from the JASPI specification and, in common with the majority of Elytron features, this can be used outside of the application server.  To demonstrate this feature Darran has created a demo showing how to integrate the WildFly Elytron JASPI implementation with a standalone Undertow server.

 

JBoss Out and About

 

Eric Schabell will be attending All Things Open in Raleigh, North Carolina from October 21st to 23rd to give his presentation "10 Steps to Cloud Happiness" and also a lightning talk on "How to Jump Start a Career in Open Source".

 

This upcoming week sees EclipseCon Europe take place in Ludwigsburg, Germany from October 23rd through October 25th with the Che and Theia Contributor Summit taking place the day before the conference.  Red Hat will be attending with many Red Hatters presenting Che related sessions through the conference.

 

Claus Ibsen was recently in Minsk, Belarus to attend the JFuture 2018 conference where he gave a presentation and workshop on Camel and Microsystems.

 

James Falkner and Cesar Saavedra were recently at the Microsoft Ignite 2018 conference in Orlando where they gave a presentation demonstrating how to deploy MicroProfile apps on Microsoft Azure using the Azure Open Service Broker.  The presentation included a demo which started with the classic Minesweeper game and integrated a scoreboard backed by Azure's Cosmos DB service.

 

New Releases

 

 

That's all for this week's edition of the Editorial, please join us next time as we continue our journey through the JBoss Communities in search of interesting articles and news.

So in this week's entry we have a mixed bag of things to cover with no single focus area - the teams have been working across a number of areas.

 

OK so let's kick it off with a long entry from Michael Musgrove on the Narayana team about how to evaluate STM implementations. As Mike says at the start of the article:

 

"Software Transactional Memory (STM) is a way of providing transactional behaviour for threads operating on shared memory. The transaction is an atomic and isolated set of changes to memory such that prior to commit no other thread sees the memory updates and after commit the changes appear to take effect instantaneously so other threads never see partial updates but on abort all of the updates are discarded."

 

This is the first article in a series so if you're interested in transactions (and let's face it, who isn't?!) keep watching the Narayana blog.

 

There are a few entries on Hibernate to report on this week. The first from Guillaume talks about how to use Hibernate ORM with JDK 11. Then Yoann announced the release of Hibernate Search 5.6, 5.9 and 5.10. And of course no editorial would be complete without referencing the regular Hibernate Community Newsletter!

 

Meanwhile Mr Camel himself, Claus Ibsen, has been to JavaZone and has written a report, a photo from which is below!

 

 

Finally for this week Cheng has written an article on building and deploying containerized Java Batch Applications on OpenShift!

 

OK that's it for now! See you next time.

Welcome to another edition of the JBoss Editorial, this edition covering articles which have been posted in the community over the last month while many of us have been on vacation.

 

Application Safety, Correctness and their relationship to Service Mesh

 

Service Meshes in general, and Istio in particular, have gathered a lot of momentum over the last few years with their appeal to developers being the ability to support robustness, tracing, traffic management, security etc. thereby removing much of the implementation complexity from the applications themselves.  While these service meshes allow much to be offloaded, simplifying the application developer's task, they do not remove the responsibility for ensuring the correctness and safety of the application from the developer.  Christian has been working with the Istio community for a long time and is often asked about this topic, for a better understanding of why the application cannot cede responsibility to the service mesh checkout his post on Application Safety and Correctness where he tackles this topic in great detail.

 

Kubernetes and Application Servers

 

In the first of a series of articles comparing the role of Kubernetes and Application Servers, Ken lays the groundwork by posing some questions on the future of application servers and introducing containers and how they are beneficial for applications.  The next articles in the series will delve deeper into this topic, exploring the problem space applications servers are intended to solve and provide comparisons with Kubernetes.

 

Integrating A-MQ 6.3 with JBoss EAP 7

 

The Red Hat JBoss EAP 7 application server comes with an embeddable message broker, ActiveMQ Artemis, which provides support for the JMS API however this is not the only option for supporting the JMS feature set.  Through integration with JCA resource adapters the JBoss EAP 7 application server can be configured to use an external broker, such as A-MQ 6.3, to support the JMS requirements.  The necessary changes are easy to make and are ably demonstrated by Abraham who covers not only the configuration but also provides an overview of the components and an overview of how the integration works.

 

Securing Apps and Services with Keycloak

 

The recording of the latest DevNation Live session, Securing apps and services with Keycloak, is now available for watching online.  In this session Stian discusses OpenID Connect vs SAML, how to secure applications and services, data and process flows for securing various types of applications and present examples covering HTML5/JavaScript, PHP and REST services with Node.js.

 

Managing Certificates from Lets' Encrypt using the WildFly CLI

 

Farah has written a great post discussing the new support available in WildFly for obtaining, revoking and checking certificates from Lets' Encrypt.  Through simple CLI instructions you can now ensure your application server is secured using free certificates trusted by all major certificate chains.

 

WildFly Swarm becomes Thorntail and Introduction to SmallRye

 

There have been a number of significant changes in the MicroProfile work over the last few months, not least of which are the change in name from WildFly Swarm to Thorntail, after much feedback from the community, and the creation of a community driven, vendor neutral project hosting implementations of the various MicroProfile specifications.  For more information checkout Antoine's post where he provides more background on the changes and covers what will be happening next with the Thorntail team.

 

Generate News Automatically with Apache Camel and WordPress

 

The recent release of Apache Camel 2.21 introduced a new Camel WorkPress component allowing camel routes to publish articles to WordPress; when combining this new component with Natural Language Generation this creates the ability to automatically generate articles and publish them to sites.  This topic is of great interest to Ricardo who has created a simple demonstration showing how soccer news can be generated and published automatically.  The demo is simple and leaves scope for exploration especially if you are interested in other topics such as Artificial Intelligence.  Have fun playing around .

 

Hibernate Community Newsletter

 

In Hibernate Community Newsletter 16/2018 you will find articles explaining how the JPA Persistence Context works, how catalog based multi-tenancy works and why you should consider it, a tutorial showing how to develop a JPA and Hibernate application using Kotlin, how to use Spring and Ehcache as a second level cache and how you can use Hibernate ORM with the CData JDBC Driver for Redis as an alternative to Hibernate OGM.

 

In Hibernate Community Newsletter 17/2018 you will find articles discussing how to handle the No Dialect mapping for JDBC type issue, an explanation of how optimistic locking works with JPA and Hibernate, an article on Hibernate Search, how to support multi-tenancy using catalog and scheme based multi-tenancy, an introduction to how table relationships are mapped and a demonstration of entity attribute validation using the Hibernate Validator project.

 

Data Reconciliation with Digital Process Automation

 

Automation processes involve the collection and processing of data from numerous sources, both automated and human, and can often lead to inconsistencies within the data due to inaccurate input, mis-aligned processes, outdated information etc. and create challenges for the organisation.  The process developer may have the option to unwind the process to preserve data integrity however it is often necessary to incorporate a reconciliation step allowing the organisation to define how data inconsistencies will be resolved.  In his article on this topic Donato discusses the options available to the process developer, starting with the traditional approach of handling the communication through a sub process and then proposing a more flexible, and less intrusive approach using decorators.

 

OptaPlanner Unit Testing using Excel or LibreOffice

 

When developing unit tests for business constraints we often develop test cases consisting mainly of boilerplate code resulting in test cases which may not be as intelligible as we would like, may not accurately represent the business constraints explained to us by the business experts, or may reflect a misunderstanding of the constraints.  Ideally we would like the business experts to define these test cases using tools with which they are comfortable and which provide more clarity.  Musa described one solution to this challenge, allow the business experts to define their use cases using spreadsheets and the developers to focus on the implementation of the constraints.

 

Batch Processing with JBeret and Red Hat Developer Studio

 

Developing batch applications has come a long way over the last few years, with the introduction of the JSR 352 java standard and support in IDEs such as Red Hat Developer Studio it is now much simpler to develop batch applications and deploy them to application servers such as WildFly.  To demonstrate how simple it now is, Cheng takes us through the necessary steps for creating a simple batch processing application, deploying the application into WildFly and performing batch processing operations.

 

RESTEasy Tracing Now Supports JSON

 

Weinan recently wrote an article introducing a new capability of the RESTEasy Tracing feature, the ability to return tracing information in JSON format to enable easier processing of tracing information by applications.  This capability is currently available through their 4.0.0-SNAPSHOT builds and expands on the existing Tracing feature which returns the tracing information using a human readable text-based format.

 

GraalVM and Camel

 

Luca has been playing around recently with the GraalVM and exploring how to create a native image in order to run Camel routes in JavaScript, for more details and a link to his example checkout his post where he demonstrates how this can be achieved.

 

JBoss Out and About

 

Eric Schabell is continuing his travels, having recently presented at the Red Hat Partner Community Meetup in the Netherlands, where he gave a preview on the application development product portfolio, timelines and what is driving their future development, Eric will shortly be heading for the All Things Open conference in Raleigh where he will give his presentation entitled 10 Steps to Cloud Happiness.

 

Next week also sees Dimitris, Pavol, Michael and Erik present at the Red Hat Forum 2018 in Zurich where they will be covering topics such as Istio Mesh, the future of Enterprise Java and teaching programming using Minecraft and OpenShift and also includes a keynote session by Jim Whitehurst, Red Hat's CEO.  The event is free so register now if you are interested in attending.

 

New Releases

 

 

That's all for this instalment, please join us next time for another spin through the JBoss Communities in search of more news, articles and releases

If you are, like me, in Europe now, you must know that it is (ridiculously) hot right now... But despite this heat wave of a sort, the JBoss community, as always, have been pretty busy in the last two weeks - certainly leveraging the relative quiteness of the summer season, to get some "things done". Let's take a look at you may have missed in the recent days...

 

Fan

Techbytes

 

Let's start with some high level consideration by checking out this new article called  From Agile to Serverless. Indeed, as the buzz around "serverless" is growing up, I though it might be a good idea to remember a bit how we ended up here !

 

Zig Zag

Deploying application inside Openshift is certainly a big trend of the last year. Indeed, one of the core functionality of Openshift - autoscaling, can be the key to success, but is also not so easy to implement. So you certainly want to take look at this quite good article on Autoscaling the Red Hat Cache Service on OpenShift. (and if you wonder, Red Hat Cache Service is based on Infinispan ).

 

If there is something that many of us like, as being both developer and member of JBoss Community, is to find way for products to integrate in way that match our way of working - rather than being forced to use a tool in a certain way. So, for instance, if you do not like XML, but love to work with Camel, you need to check up this little article on Polyglot Camel Routes. Along the same lines, if you have to work with JS but would like to be able to use Java instead, take a look at the following article: Adventures in GraalVM: invoke Java code from JS in native-image

. Last, but not the least, let's take a quick look at how How to set up RBAC on Red Hat AMQ Broker!

 

Community

 

The JBoss community encompasses several other ones and one of the most thriving is certainly the Hibernate community. And the best way to keep up with this one is to check out their Hibernate Community Newsletter 15/2018. One of the main feature of this month entry is the interview of one of the developer: Meet Jan-Willem Gmelig Meyling.

As always, our own Eric D. Schabell has been quite productive in the last two weeks and released not one, but two articles on Opensource.com: What data is too risky for the cloud? and Why you can't move everything to the cloud. On top of those articles, he also released the fourth part of his ongoing series for DZone on 3 Pitfalls Everyone Should Avoid With Hybrid Multi-Cloud (Part 4).

 

Releases, releases, releases...

As alwasy, the last past two weeks have seen their fair share of releases - so here is a small recap:

 

Decaf'

 

The JBoss community and products are not living in their own little planet and there is all action happening around them that you may like to be aware of. Openshift being a rising interest in the Java world, it's certainly make sense to know about the Renaming of OpenShift Origin with 3.10 release. Also of interest for the Java developer would be those the two next articles. The first one cover the not so easy topic of Container-native integration testing

and the second adresses the problematic of Natively compile Java code for better startup time. Both are certainly worth checking out!

 

Hopefully, you have found something in this week's editorial to pique your interest and give you something to explore while waiting for next week's installment. Join us here next week for more news from the JBoss Community.
