Weekly Editorial

325 posts

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.

Welcome to the weekly roundup from the JBoss Community. Read on for an overview of the week's news and releases.

 

How to defeat gerrymandering and create fair elections

Over the years, politicians have redrawn electoral voting lines to gain an unfair advantage. This has led to district boundaries with shapes that have no obvious pattern or reason other than political gain. When districts are redrawn you can sway an elections results without changing a single voter’s mind. Can OptaPlanner draw fair electoral boundaries and save democracy?

 

Easy Workitem installation (jBPM WorkItem Repository)

The jBPM team has added the ability to install workitems hosted by the  jBPM Workitem Repository on any running KIE Worbench instance directly from the repository. itself This lifts some limitations of installing workitems which was so far only possible from within process editors inside each running workbench. It also allows for future integrations with other runtime systems that can take advantage of the hosted workitems.

 

3 Pitfalls Everyone Should Avoid with Hybrid Multicloud (Part 4)

This article series highlights three pitfalls you should be aware of when transitioning into hybrid multicloud environments.

 

Enterprise Integration for Ethereum

Ethereum is distributed and decentralized, but it is mostly a closed system with the embedded ledger, the currency, and the executing nodes. In order to be useful for the enterprise, Ethereum has to be well integrated with existing legacy and new systems. In this post Bilgin Ibryam presents the Apache Camel Connector for Ethereum.

 

Inspect HTTP Sessions in Undertow

The Undertow WildFly subsystem has been enhanced and provides new operations to inspect HTTP sessions.

 

Log all configuration changes to WildFly

There is a feature to record all configuration changes to an in-memory log per host or server, it records any change performed on Wildfly, for example: deploy an application, add a datasource, change any configuration, add any resource. This blog post will show how it works.

 

Five Advantages of Log-Based Change Data Capture

In this post Gunnar Morling answers the question of "why use a log-based change data capturing tool such as Debezium over simply polling for updated records?"

 

Performance baseline for jBPM 7 (7.8.0)

The aim of this article is to measure the base performance of jBPM so as to set a baseline and to answer the basic question of how good jBPM performs when it comes to execution. This is not to be seen as competitive information or show that jBPM is faster or slower than other engines, but more for setting a stage and open the door for more performance tests that can be performed in different types of environments.

 

Red Hat Process Automation Manager v7.0

In this post Kris Verlaenen introduces Red Hat Process Automation Manager v7.0. This is the latest major release of Red Hat JBoss BPM Suite product, which brings with it a product rename that reflects the broadened scope of the software.

 

Maciej Swiderski is the new jBPM community lead

In this post Kris Verlaenen announces that Maciej (aka "Magic") Swiderski will officially become the new jBPM community lead.

 

Releases

 

This editorial looks like it's going to be about release after release after release! The teams have really been busy!

 

First Marc has written a few articles about the new APIMan release (version 1.4) followed quickly by 1.4.3 (if anyone finds 1.4.1 and 1.4.2 please return them to Marc care of JBoss!) He's also found the time to write about how you can customise your path patterns for the gateway.

 

While we're at it, of course let's not forget about the equally interesting Hibernate Community Newsletter. And on the theme of Hibernate, Hibernate Search 5.10 has another maintenance release and Hibernate ORM 5.1.15.Final along with ORM 5.3.2.Final were also released by the team, followed closely by OGM 5.4.0.Beta2.

 

Other releases over the period include Infinispan 9.3.0.Final, Thorntail 2.0.0.Final, a couple of RESTeasy releases, ByteMan 4.0.3, the ever popular Debezium had a release, Apache Camel 2.22 came out, and Keycloak 4.1.0.Final (check out this article around Keycloak on Kubernetes too!)

 

Not quite a release but definitely newsworthy, Mario Fusco is the new Drools lead! Well done Mario!!

 

Chritina Lin has written a great first article on contract first design with Apicurio and Fuse.

 

Let's wrap up with a personal favourite: the JBossTS team have done some interesting work around the LRCO optimisation and you can read about it in this article.

 

OK that's it for now. Enjoy!

I always enjoy watching all the different countries with varying backgrounds come together to play in World Cup Football.  This week has seen alot of ups and Estadio Centenario 1930.jpgdowns.  Unfortunately, the US Team did not qualify for this world cup but love the VW commercials urging US spectators to pull for their team -  "Cheer for Germany, they gave us the frankfurter" and "Iceland can use your support as we don't have enough people to do the wave"   Uruguay hosted the first World Cup in 1930 in the "Temple of Football".   The US placed third which has been their best finish in all the World Cups they have participated.  They placed 8th in 2002 in Korea/Japan.  I grew up playing football, AKA Soccer, and was always disappointed because the US did not qualify in the 70s and 80s.  But I always watched and had a favorite country.  Good luck to all the teams.

 

Pele - "Success is no accident.  It is hard work, perseverance, learning, studying, sacrifice, and most of all, love of what you are doing or learning to do"

 

I love what I do at Red Hat; Now on to the happenings in our open source community!

Welcome to a new edition of the JBoss Weekly Editorial. As summer comes closer on the northern hemisphere, the blue sky and sunny days do not appear to be able to hinder the community progress. No rest for the weary, ain't it? As proof, Red Hat just released Red Hat Fuse 7 - obviously built from the tremendous amount of work the Fuse community has put in the project in the last month (and releases).

 

Techbytes

 

We'll start this editorial by jumping directly into the a set of technical articles that have been released in the previous week. The first we would like to mention is The best way to write a Hibernate ORM issue test case . It will be of interest to anyone who would like to contribute a feature or a bug fix to the project, but also reveal an often under documented aspect a project: the testing framework.

 

Right after this one, let's go into something a bit more practical and take a deep look at how to Configure permissions using Elytron in WildFly 13. And, as long as we talk about our beloved app server, let's take a peak at What’s New in WildFly Management Console. Still related to Wildfly, we need to mention this interesting Introduction to Red Hat Application Migration Toolkit.

 

Events & Evangelist's Corner

 

As always, our own Eric D. Schabell has been active last week and has just released the slides of his talk at Shift Developer Conference 2018 on How to Jump Start a Career in Open Source. He was also in Scotland, just yesterday, to give a talk on Application Modernization and Migration Tech Talk at Scotland JBug Meetup Hopefully some of you living in the area will have had a chance to catch him!

 

Infinispan thanks Great Indian Developer Summit & Voxxed Days Zurich. His "world tour" of a sort is, of course, not finish, as he also attends our very own Red Hat Summit.

 

Releases, releases, releases

 

There is only one release we will mention in this section, for once, but it's a big one:  Red Hat Fuse 7 - Announcing Red Hat Fuse 7 GA!!

 

Decaf

 

Docker, and container in a more general sense, adoption have certainly increased a lot over the few last year. This adoption is also quite important in the Java and JBoss ecosystem, thus maybe this blog entry might be interesting to you too: How to install Red Hat CDK 3.4 on Fedora 28.

 

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.

This is a smaller editorial this week, but by no means does that mean we haven’t been busy!

Releases

Blogs

As stated, this was a smaller one this week, but still, some great stuff happening! Everyone have a happy summer!

Welcome to another edition of the JBoss Editorial, our regular search through the JBoss Communities in search of interesting topic for all.

 

Updates from Red Hat Summit

 

Earlier this month saw the largest Red Hat Summit conference taking place in San Francisco's Moscone Convention Center, if you missed the conference or would like a recap then we have some good articles for you to read.

 

The first article of the week covers a presentation given by Marius Bogoevici and Christian Posta and entitled "An Eventful Tour from Enterprise Integration to Serverless", taking the audience on a tour covering the basic of Enterprise Integration through the microservices and serverless computing.

 

The second article covers a presentation given by Christian Posta entitled "Lowering the risk of monolith to microservices", discussing the journey of a fictitious company as they consider a pragmatic approach for moving their monolithic application over to a microservices architecture.

 

The third article takes us behind the scenes for a look at how sessions at such a large conference are scheduled and the part OptaPlanner played in optimising the agenda.  In the article Geoffrey covers not only the theoretical challenge to the task but also the practical challenges which arose as they worked towards the generation of the agenda.

 

Would you like to get a signed copy of the book "Effective Business Process Management with JBoss BPM"?  The author of the book, Eric Schabell, was signing and giving away copies at Summit and still has a few copies left.  Getting hold of a copy is easy, add a comment on the article sharing your JBoss BPM story and let Eric know you have done so via twitter.

 

Querying Debezium Change Data Events With KSQL

 

With Debezium's ability to turn database updates into an event stream, publishing the stream through Kafka Connect and allowing applications to respond near instantaneously to each committed change, we have a very powerful mechanism for monitoring and reacting to database changes and when coupled with KSQL, a streaming SQL engine build on Kafka Streams, it enables the ability to interactively process the Change Data Events as they arise.  For more information on this topic, as well as a demo showing how to start a KSQL instance, map KSQL streams to Debezium topics and repartioning of data, checkout Jiri's post.

 

Using the Contract Net Protocol in jBPM

 

The Contract Net Protocol allows multiple agents to announce and bid for contracts in order to complete an item of work, coordinating the execution of the work through an announcement/bidding/awarding process and can be modelled in jPBM through case definitions where individual phases of the protocol can be externalised via processes.

 

Apache Camel Language Support for Eclipse, VS Code and OpenShift.io

 

The Camel Language Server, enabling completion and documentation for camel URIs, is now available for download through the Eclipse and VS Code marketplaces as well as being available in OpenShift.io.  If you work with Camel on these platforms then take a look at Aurélien's article where he explains how to download and enable the plugins within each environment.

 

Hibernate Community Newsletter

 

The latest version of the Hibernate Community Newsletter is out with new articles from the Hibernate Community.  In this edition of the newsletter you will find articles explaining how JPA and hibernate can simplify data persistence, how to bootstrap JPA and Hibernate within Java SE, a beginner’s guide to Linearizability, mapping a ZonedDateTime, the Dirty Read phenomenon and many more.

 

Narayana JDBC Integration for Tomcat

 

If you are interested in using JTA capabilities within your tomcat deployment then take a look at Ondra's article discussing the integration of Narayana within tomcat.  Ondra discusses three different approaches to integration, examining the setup for the Narayana JDBC transactional driver, the Apache Commons DBCP2 library and lastly IronJacamar JCA.

 

JBoss Out and About

 

Eric Schabell will be visiting Edinburgh, Scotland on June 6th to give a workshop entitled "AppDev in the Cloud".

 

New Releases

 

 

That's all from this week's editorial, please join us again next week when we will take another spin through the JBoss Communities in search of interesting articles.

Sorry, we missed last week. We’re pulling double duty this week to get you all caught up on the latest with JBoss!

 

Red Hat Summit 2018

First, we would like to thank everyone who attended Red Hat Summit 2018 in San Francisco! This was a tremendous week full of amazing talks, keynotes, and fun! Middleware played a big role in many of the keynotes, which if you happened to miss are available on our YouTube channel. We hope you all enjoyed this year’s Summit as much as we did!

Welcome to another edition of the JBoss Editorial, our regular dip into the JBoss Communities to discover topics of interest to you all.

 

Red Hat Summit is finally here!

 

Next week sees many of us returning to San Francisco’s Moscone Center for this year's Red Hat Summit and OpenShift Commons events, taking place from Monday 7th May through to Thursday 10th May.  If you are visiting the area or attending either event then arrange a meet up with any of the developers and talk about your favourite projects.

 

While at Summit you may be interested in attending a hands-on lab to learn more about technologies which interest you, this year we have labs covering Cloud Native Applications, running OpenShift Container Platform on Azure and others.  Siamak, one of the presenters of the Cloud Native Applications lab, has a more detailed introduction covering the lab and what sessions you can expect.

 

Christian Posta will be giving a number of sessions at Red Hat Summit including

  • Istio with Zach Butcher
  • Evaluating when you should move to microservices
  • Messaging patterns, Event Driver Architecture and Functions as a Service with Marius Bogoevici

and finally a panel session with Louis Ryan and William Morgan discussing Service Meshes.

 

Eric Schabell, author of Effective Business Process Management with JBoss jBPM, will be joining a number of Red Hat authors during the week to meet developers, chat and sign copies of their books at the DevZone.  Stop by and meet your favourite author!

 

JBoss EAP Continuous Delivery

JBoss Out and About

 

Over the last month and a half Galder has been giving sessions at both Javaland and Devoxx France.  Galder's presentation at Javaland explored a number of Java RPC frameworks from the perspective of Infinispan's Remote API, evaluating which could be a good candidate for Infinispan should the need arise.  At Devoxx France Galder first teamed up with Clement Escoffier from the Vert.x team to deliver a 3 hour session on streaming data analysis, they both then teamed up with Google's Ray Tsang to deliver a 3 hour streaming data hands-on workshop.

 

New Releases

 

 

That's all for this week, please join us next week when we will bring you more news from Red Hat Summit and the JBoss Communities.

Continuing from last week, thank you, Mark, we have a number of jBPM related posts this week. There are also some related Hibernate posts. Shall we start with releases?

 

Releases

Both of these are bug fix releases.

 

Blogs

Nicola Ferraro posted a very well thought out and in-depth article about the Saga pattern in Apache Camel (version 2.21.0 or higher). Not familiar with the Saga pattern, not sure when, or how you would use it, this blog is for you. Head on over to his blog to learn more.

 

Eric Schabell has been on the West Coast of the USA for a few weeks. While there, he was invited to speak at the Portland Java User Group (PJUG). If you weren’t one of the lucky 29 people in attendance, that isn’t a problem. You can hit the recap and see his slides over on his blog.

 

Vlad Mihalcea released the weekly Hibernate Community Newsletter a few days ago. It highlights a number of articles, releases, and Q&A for the Hibernate suite of projects. Certainly worth a glance to get back up to speed with the latest happenings within that community!

 

As stated earlier, jBPM had a number of blog posts this past week. Two of them (http://mswiderski.blogspot.com/2018/04/jbpm-work-items-repository-tips-tricks.html and http://mswiderski.blogspot.com/2018/04/jbpm-work-items-are-really-simple.html) relate to Work items. Work items are the way to build custom services which can be used within a process. Maciej teaches more in the mentioned blog posts. He also wrote about KIE Server custom queries in jBPM 7.8. Lastly, there’s a recap of bpmNEXT 2018 Day 3 over on Kris Verlaenen’s blog.

 

We hope you have enjoyed this week’s JBoss Weekly editorial! We also look forward to seeing you at Red Hat Summit 2018 in San Francisco!

There has been a lot of BPM related activity this relatively quiet week.

 

jBPM Lead Kris Verlaenen has written an article about his attendance of bpmNEXT 2018. In fact it was such a good day 1 that he had to span it across two articles! Kris also followed up with a couple of entries on day 2 activities. Meanwhile Edson Tirelli has written a complimentary piece that points out videos to the various sessions so everyone can enjoy.

 

Also this week Eric has been talking about how easy it is to install OpenShift Container Platform 3.9 as well as part 3 of his series on the Open Innovation Labs residencies.

 

Christian writes about the book he and Burr Sutter have written about Istio Service Mesh and which has just been released. Congrats guys!

 

Finally Hibernate OGM 5.4.0 Alpha 1 is out and the Keycloak team are conducting a questionnaire for users so please look at it.

 

OK that's it for this week!
