Hello, everyone! Welcome back to the pre-Summit JBoss Weekly Editorial! I’m sure you all know that Red Hat Summit is happening next week, we’re looking forward to seeing you there! Many of us will be giving talks or hanging around at the booth, please stop by and say hi.

As you might have guessed, a lot of the information for this week’s editorial will be about Summit. That isn’t to say that there hasn’t been some other stuff that has happened. Let’s get into it!


Byteman has pushed out a couple of new releases: 3.0.10 and 4.0.0-BETA5 to be exact. 3.0.10 is a bug fix release and intended for JDK8 and earlier. 4.0.0-BETA5 contains the same bug fixes as 3.0.10 and some others targeting JDK9. Of course, you can checkout the release notes for the version you’re interested in.


Teiid 9.3-Beta1 was released last Friday. You can read the release on the blog for more information. This release includes support for LEAD/LAG/FIRST_VALUE/LAST_VALUE functions. There’s also been some initial work done for Couchbase connectivity and SQLAlchemy/Superset. The team would appreciate any feedback you have if you’re using any of those data stores.


The Infinispan group released Hotrod clients C++/C# 8.1.0.Final earlier in the week. There are a number of feature requests and enhancements that went into this release, as well as a good helping of bug fixes. Read more about them in the release notes.

Apache Manifold 2.7 was released earlier in the week. It includes a brand new UI, SharePoint 2016 support and improved connectors for a number of different data stores. 40 improvements and issues have been resolved in this release. Congratulations to the team on a job well done!


Of course, there’s all the stuff happening at Red Hat Summit. Quite a bloggers projects being showcased at Summit. This is turning out to be a spectacular event this year, you certainly won’t want to miss it!


There’s also the Great Indian Developer Summit wrapping up this week. Galder Zamarreño is there speaking about Infinispan of course! His talks touch on Big Data and reactive applications using Infinispan. Both wonderful topics!

It’s a busy week for us coming up, hoping to see you there!

Other goings on

We’ll finish up this editorial with some general happenings within the community.


Those of you following Debezium will already know, but Randall Hauch has stepped down from running the project and has taken a position with Confluent! We wish him the greatest of success in his new position! To fill the void, Gunnar Morling has stepped up and will be filling Randall’s place. Gunnar is no stranger to open source and data. He’s worked for a number of years on Hibernate, Bean Validation as well as other. We’re looking forward to great things coming from Debezium and Gunnar!


In keeping with the data theme, Guillaume Smet wrote about Simple Query String on the Hibernate blog. The feature came out with Lucene 4.7.0 and support in Hibernate Search version 5.8.0.Beta1. It is a powerful way of building up a query without having to wade through all the Lucene query documentation. Hibernate Search has a DSL for it and the team is looking for feedback. If this is something you’re using, or looking at using, please give them your feedback.


In the Vert.x camp, Benoit Hediard blogged about creating an application using Angular on the front-end and Vert.x on the back end. He goes through reasons to use this stack and also walks you through a basic proof of concept to get you going.


Corinne Krych blogged about debugging Karam tests over on her blog. If you’ve been using Karma it may not always be that easy to get things working. Head over and read Corinne’s example and setup for getting started debugging those tests!


Have you thought about securing your containers? Eric Schabell certainly has. In fact, he wrote a post about getting all those things secured. It’s certainly worth the read if you’re using containers and need to make sure everything is on the up and up!


Our last entry this week comes from Christian Posta about calling your services and why it’s difficult. Microservices isn’t easy, and getting them right is even more difficult. Christian continues talking about the most difficult parts of microservices.


Thank you all for reading and again, we’re looking forward to seeing you all at Red Hat Summit!

We're back after a couple of weeks break and where to start? The obvious candidate is BPM because the team seem to be dominating the feeds recently! The BPM product architect and jBPM project lead, Kris Verlaenen, has been prolific with a series of articles about the bpmNEXT conference he is presenting at. Take a look because there are some interesting perspectives on where BPM in general is going in the future. Kris has an introductory article here too. And related to BPM, Maciej has written about a fairly common requirement, how to send emails from within a process with a nice worked example. In an earlier article, Maciej also took the time to show the new Case Management Showcase application in the BPM workbench.


Not to be outdone, the Hawkular team have a few important announcements. They had a talk at CloudNativeCon in Berlin.



But then there was the announcement that we are getting involved with the Jaeger project!


"This new version of Jaeger provides very similar functionality to Zipkin, which is focused on visualising individual traces. It does not have the aggregated views currently supported in Hawkular APM - however from discussions with the Jaeger project, they are keen to be able to provide aggregated views. Therefore we have made the decision that, rather than refactor the Hawkular APM project’s model to be more OpenTracing compatible, it makes more sense to collaborate on the Jaeger project."


Keep watching this space for further updates!


A few more noteworthy announcements and articles in the last couple of weeks include:



There were the usual flurry of project releases, such as WildFly Swarm, Arquillian, Infinispan and ByteMan. Well done to those teams!


OK, that's it for this week. See you next time!

It has been a few weeks since we last provided an update on the activities within our Communities and for that we apologise.  With this edition of our Weekly Editorial we are hoping to rectify this mistake and take you on a trek through not one, not two but three weeks full of news.  I hope you enjoy the experience and find something of interest.


New Foray into Serverless


Emmanuel recently wrote a post describing some of the efforts taking place within the Fabric8 Funktion project to explore serverless architectures.  In their experiments they discovered a remarkable performance improvement when replacing 'if' branches within serverless functions with invocations to an 'if' method, something they are calling IF as a Service (IFAAS).  While not part of the current MVP they have also been experimenting with defining 'else' statements as functions although 'for' loops are proving problematic.  If you are interested in learning more about this initiative then head over to or look for advice beside the date on the original article.


Hawkular Monitoring and Alerting


This week we have a number of articles on Hawkular technologies, a set of OpenSource projects focussing on Monitoring and Alerting solutions of applications and deployments within standalone, on-premise and Cloud environments.


In the first article of the week we investigate the trade-offs we need to consider when determining how best to adjust the sampling rates for applications being traced within a distributed environment.  Should this be an application driven decision or an infrastructural driven decision?  Should this be driven through static configuration or dynamic configuration?


Our second article continues the distributed tracing theme by discussing how the OpenTracing standard will be supported within the upcoming Apache Camel 2.19 release and covers how to explicitly instrument a camel application, how to achieve the same using the Spring Boot annotations, how to integrate the OpenTracing java agent and examples demonstrating the distributed tracing functionality in action.


The third article introduces a new tool for monitoring java applications, the hawkular java agent, while our fourth article introduces the Hawkular OpenShift agent which can retrieve metrics from pods exposing Prometheus or Jolokia endpoints.


Our final article introduces Hawkular Alerting, a component which enables the querying of Elasticsearch servers with results emitted as Hawkular Events.


Bean Validation 2.0 Alpha2 is out


The Alpha2 version of the Bean Validation 2.0 API and Spec is now available including improvements and clarifications related to the validation of container elements, new constraints based on feedback from the Community and an updated TCK.  If you wish to try out these features within your tests then Gunnar demonstrates how this can be achieved using WildFly 10.


Google Summer of Code


JBoss is again taking part in the Google Summer of Code (GSoC) as a mentoring organisation, GSoC is an initiative lead by Google to encourage participation in OpenSource.  The deadline for submitting proposals has now passed and we have moved on to the second phase, evaluating proposals to determine which to accept.  Good luck to all of you who are involved!


Pushing Notifications with Red Hat Mobile Application Platform


Delivering notifications to clients using the Red Hat Mobile Application Platform is a very simple task with the platform allowing for notifications to be sent to all devices which are subscribed to a particular 'category' as well as to an explicit set of specified users.


Integrating Keycloak with Microsoft Active Directory Federation Services


One of the interesting capabilities of Keycloak is the ability to use external services as brokered identity providers, for many this will mean integrating with Microsoft Active Directory Federation Services.  Setting this up is not as daunting a task as it may sound, Hynek has provided details for all the steps for both Keycloak and Active Directory.


Accessing the BRMS Internal Git Repo within a Container


When running BRMS in a standalone, on-premise environment you may have accessed the BRMS internal Git repository using your development tooling, if you have tried to do the same when running within OpenShift then you will have quickly realised this feature is not enabled by default.  Rectifying this is straight forward as Eric demonstrates in his Tips & Tricks series, allowing you to once again gain access to that internal repository via your tooling.


Get Ready to Migrate, jBPM 7 is Coming


With the upcoming release of jBPM 7 it is now time to understand the necessary steps for migrating from your current jBPM 6.5 installation.  The migration is a reasonably simple process but will involve migrating your workbench, database and updating the configuration of the new KIE server.


Scala Support in Vert.x


The Vert.x team have recently added support for Scala as a language binding, providing support for all Vert.x modules.  The team also provide a quickstart showing the integration in action, discuss testing using ScalaTest and demonstrate how to make asynchronous invocations using Scala Futures.


Hibernate News


This week we are fortunate to highlight two issues of the Hibernate Community Newsletter.  In Newsletter 6/2017 you will find articles discussing the differences between first and second level caches, how to implement the soft delete pattern, integrating Hibernate Search with Spring Boot, DTO projections when using JPA and many more.  In Newsletter 7/2017 you will find articles discussing how to identify statements which lead to a failure during batch processing, integrating with CockroachDB, mapping one-to-many relationships, implementing multitenancy and more.


C++ Clients for Infinispan


When integrating clients with Infinispan it is natural to think in terms of what can be done through the Java clients but did you know that Infinispan 8.1.0 added the ability for C++ hotrod clients to receive and process events?  Not only can you register a client listener with the hotrod server but you can also reference filters and converters deployed within the server.


Apache Camel is 10 years old!


On March 19th 2007 James Strachan submitted the very first commit to the Apache Camel codebase, originally created as a sub-project of ActiveMQ.  The first release of the project was made on July 2nd of the same year and it looks as if we can expect some celebrations to coincide with the anniversary of the release.


JBoss Out and About


Red Hat Summit 2017 will soon be upon us, taking place in Boston from May 2nd to May 4th.  This year we are trying something new, a Taste of Summit, through which you will get free access to many of the sessions from the conference and early access to session previews.  While there you should also check out the AppDev and DevOps labs.


Eric Schabell is attending a number of conferences to give his presentation entitled "App Dev in the Cloud".  His first appearance was at Codemotion Rome 2017 (slides available) and will be followed by QCon New York, June 26th to 30th, and All Things Open, Raleigh, North Carolina from October 23rd to 24th.


The Drools, jBPM and Optaplanner teams will soon be hitting the road to present at bpmNext, Santa Barbara from April 18th to 20th, and Red Hat Summit.  If you are interested in these technologies then check out the schedule of their presentations, especially the talk on Case Management given by Kris and Maciej.


The Hibernate OGM team will be presenting at Devoxx UK, taking place in London from May 11th to May 12th, while the Infinispan team will be presenting at Devoxx France, taking place in Paris from April 6th to April 7th.


Bilgin attended CloudNativeCon and KubeCon Europe 2017 where he gave his talk on Cloud Native Patterns (video and slides included) and listened to many other speakers giving their own presentations.
