December 2016 Previous month Next month

This has been a tough year for the passing of some great actors and actresses.  On December 27th "Princess Leia" passed away, and her mom, Debbie Reynolds, passed away the day after.  I was 9 years old when Star Wars came out and have enjoyed the movie franchise since the moment I saw Carrie Fisher.  About 30 years separated the releases of Return of the Jedi and the Force Awakens, but it was well worth the wait.  I think Mark Hamill said it perfectly, Carrie was one-of-a-kind who belonged to us all- whether she liked it or not. She was OUR Princess, darn it, & the actress who played her blurred into one gorgeous, fiercely independent & ferociously funny, take-charge woman who took our collective breath away. Determined & tough, but with a vulnerability that made you root for her & want her to succeed & be happy. Carrie will be in Episode VIII and it will be interesting to see how they handle her absence in Episode IX.  Carrie, Thanks for taking our breath away on and off the big screen!

Holiday season have officially started and we certainly wish you are all off to your familly and friends - if you actually are, please, stop reading this, close your phone or laptop and pay attention to your relatives for once ! Have a merry christmas !!!

 

Coffee Shop Christmas Village

 

Microservices are commodity

 

Before jumping into some in-depth, technical articles, let's take a short step back, and look at things from higher vintage point with this excellent article on Microservices are Commodity.

 

Riding a camel for Xmas ?

 

Camel are certainly not the first animal one associates with Christmas, but this should certainly prevent anyone to enjoy this cool article on Camel Live Reload of XML routes. An if you are looking for more in depth information on Camel itself, you probably want to check out the Status of Camel in Action 2nd edition book. Or, if not, at least take a peak, at this article on Red Hat JBoss Fuse - Automate integration CI/CD processes. In any case, after that, you'll be ready to cross any desert...

 

Techbytes - Treat yourself a Xmas gift - dwelve into Infinispan 

 

As the holiday season generally means finally a bit of time to do some long due exploring of some cool, new technologies, so the Infinispan and the Hawkuler one have both though of you, and released some pretty neat articles. On the Infinispan side, a first article, Infinispan: Spring Boot Starters, walk you through setting up Infinispan as part of a Spring Boot app - certainly an efficient way to start using Infinispan, if you are already familliar with Spring Boot (otherwise, did you heard of JBoss Forge ? ).

if you are already an Infinispan user, the second article might be more up your alley. It's a more in depth introduce some major changes, coming in 9.0 : Data Container Changes Part 1. Be prepare for the next big thing coming in Infinispan !

 

Fiddle for Drools and CLI for Hawkular

 

If you, like me, have to play around with Drools on a regular basis, i'm pretty sure you'll find this nugget very useful: Introducing the new Drools Fiddle. Along those lines, a brief introduction to a pretty neat CLI tool for Hawkular - Hawkinit will probably be equally useful(ok, i'm partial, I just love CLI tools...).

 

Releases, releases, releases...

 

As always, the JBoss Community projects have released many new version - especially a first CR for Keycloak 2.5 and for an exciting new version of Hibernate Search using Elasticsearch !

 

 

Decaf'

 

Already to jittery for Java ? Time for something else ? Well, then I could not pass anyway this opportunity to mention this article from last week describing

How to get started with Microsoft SQL Server on Red Hat Enterprise Linux ! SQL Server on Linux ? Aren't we living interesting times !

 

Also, a bit more closer to the Java root of the JBoss Community, the third part of a very interesting series about using Red Hat JBoss Data Virtualization on OpenShift: Part 3 – Data federation. Certainly take a look at it, especially if you are not familiar with JBoss Data Virtualization (or its Open Source pendant, Teiid). It think it may pick your interest...

Welcome to another edition of the JBoss Weekly Editorial! We are excited to bring you another packed week of JBoss and Red Hat Middleware news. The end of the year is nearly here, but that doesn’t mean we’re slowing down.

Releases

Let’s start with the new bits during the week, shall we?

Teiid continues to move closer to it’s 9.2 release with 9.2 Alpha2. Hashing functions, including md5, sha1, sha2-256 and sha2-512 have been added along with a number of issues being closed with this release. Just over 70 issues have been closed on the road to the 9.2 release currently slated for early to mid February.

Wildfly Swarm has recently released version 2016.12.1. A number of issues have been closed with this release including improvements to UberJar and war cleaning, fewer boot-time warnings, significant improvements to Windows support and JavaDocs! Wildfly Swarm is a slimmed down version of Wildfly Java Application Server for use with Microservices.

Changes to the JDK9 have necessitated another release of Byteman. Andrew Dinn released version 4.0.0-BETA1 earlier this week addressing those changes. Byteman is an invaluable tool for tracing, monitoring and testing Java application JDK runtime code.

On the product side of things, Red Hat Single Sign-on recently released version 7.1 Beta. Included in Red Hat Single Sign-on are features for OpenID connect, Red Hat JBoss Fuse integration, a Node.JS client adapter, SSSD integration, user storage SPI and more! If you’re in need of an SSO solution, look no further.

Notable Blog Entries

This past week includes a number of notable blogs done by the community.

To kick things off, Jason Green blogged about Jigsaw’s Missing Pieces. He includes links to the various issues in the OpenJDK project. Jason breaks down the "missing pieces" into three categories: Reflection issues, dynamic introduction and alteration of modules, and interoperability with alternative module system. He remains hopeful suitable solutions can be found and implemented.

Next, we have Ken Finnigan’s post about whether to WAR or JAR with Wildfly Swarm. Ken briefly describes how to obtain a JAR and a WAR using Maven. He also discusses pros and cons of both approaches. The recommended approach is to us a war with Wildfly Swarm, however, that isn’t a hard rule.

Juraci Paixão Kröhling talked about the recent improvements to Hawkular APM for OpenShift this week. He included steps to get everything setup on Fedora 25. There are also examples to follow along that Juraci mentions!

Vlad Mihalcea discusses what has happened within the Hibernate Community recently in his Hibernate Community Newsletter post. There are many blogs, issues, releases and Q&A posts he links to and are well worth the read if any of them apply to your particular Hibernate usage.

Back in November a number of Red Hat employees spoke at Devoxx Morocco. Galder Zamarreño recapped his trip to Morocco and Geneva over on the Infinispan blog. Galder spoke about building reactive applications using Infinispan, Node.js and Elm.

To round out the Java related news, John Clingan wrote about MicroProfile being adopted into the Eclipse community. MicroProfile has moved quickly since it was announced back in June at DevNation. If you’re interested in joining the discussion, head over to the forums.

Todd Mancini has a somewhat lengthy, but concise blog post about porting .NET Framwork to .NET Core. You’ll want to read through that if you’re currently thinking about migrating to .NET core, or even using it for the first time!

Lastly this week, we have a piece written by Takayoshi Tanaka about getting started with Microsoft SQL Server on Red Hat Enterprise Linux. Microsoft has a simple seven step install document which Tanaka-san builds upon. He describes how to connect to the database using Visual Studio Code, Visual Studio and the command line.

We’ve had a fantastic week here at Red Hat and are looking forward to another one coming up!

 

With the end of the year coming you may be forgiven for thinking we would be winding down but the communities are amazing places full of amazing people as can be seen in this week's edition of the JBoss Editorial.

 

JBoss Data Virtualisation

 

Following the recent release of the JBoss Data Virtualisation image on OpenShift, completing the initial move of our current Middleware products in to the cloud, Cojan has begun a series of articles demonstrating the capabilities of the product and how to use them within the OpenShift environment.  In the first article of the series Cojan takes everyone through the steps necessary to deploy the image on OpenShift, from the installation of vagrant and the Container Development Kit through to the first deployment of JDV.  In the second article Cojan introduces us to the concept of a Virtual Database and explains how it can be exposed as a service using the OData protocol.

 

Of course we have not forgotten about those of you running JDV on your own machines!  Madou has an article showing how MySQL/MariaDB can be integrated with JDV in order to expose the contents of your databases.

 

Infinispan Integration, Streaming and Querying

 

The Infinispan project have also been busy this week, not only have they announced their first Beta of Infinispan 9 (see below) but they have another three published articles.

 

In the first article of the week Gustavo walks us through the necessary steps for using Oracle JDBC Cache store, covering the configuration of Infinispan and how to orchestrate the deployment with docker-compose.  The second article, written by William, discusses the Distributed Stream capabilities and the usability improvements which have been introduced in Infinispan 9 while the final article, written by Adrian, introduces Ickle, the new Query Language being introduced in to Infinispan.

 

Messaging in Cloud and at Speed

 

The standard deployment of A-MQ within OpenShift assumes the server is being provisioned for use by other deployments with access to the same project however sometimes you want to allow access from an external client.  If this is a scenario you are interested in then take a look at Michelle's article where she demonstrates how to expose the internal service to an external client.

 

When using messaging systems you will often be faced with a trade-off, a decision to relax the full guarantees of writing to disk for improved performance.  Artemis allows you to make the same trade off, allowing you to reach a speed of 50K persistent messages per second on a laptop with a delay of only a few milliseconds before the messages are persisted.

 

Garbage Collection in the VM

 

For many of us developing on the JVM we have come to trust the default Garbage Collection settings will be sufficient for our applications but what happens when your applications are pushing harder on the VM?  How do you tune the GC behaviour?  In the first article of a series discussing the GC, Matt Robson takes us through the role of the G1 (Garbage First) collector and how it works.

 

Kie Server Routing

 

One of the challenges faced by kie server clients has been the requirement to track the location of the servers being used and which kjars are running on them.  With the introduction of the Kie Server Router we now have a single service against which we can invoke requests, allowing it to handle the routing to the correct kie server instance and the aggregation of requests spanning multiple servers.

 

Hibernate News

 

The latest version of the Hibernate Newsletter is out bringing news from the community.  Within the newsletter you will find interviews with developers along with articles discussing Apache Ignite, streaming vs pagination, integrating with Camel, multi-tenancy and much more.

 

DevNation 2017 Call for Papers

 

DevNation 2017 will be taking place in Boston, alongside Red Hat Summit, from May 2nd to May 4th.  The call for papers is still open but will be closing soon, the current deadline is Friday 16th December.

 

OptaPlanner and the US Election

 

With the recent US Presidential election being in the news Geoffrey started to wonder what would be the lowest number of votes required for a candidate to win the election, naturally this is a constraint violation problem and something he knows about .  With this as his goal Geoffrey began working with OptaPlanner and created a model to determine an answer that may surprise many of you!

 

Camel Maven Plugin Donated to Apache

 

At the beginning of this year Claus wrote an article presenting a new Camel Maven Plugin which could parse your source code and validate endpoints.  After nearly a year of work the plugin has stabilised and is now being donated to the Apache Camel project.

 

JBoss Out and About

 

Heiko was recently invited to GrafanaCon 2016 where he gave a presentation on Hawkular.

 

New Releases

 

 

Join us again next week when we will bring you the latest crop of news from across the JBoss Communities.

Welcome to this week's editorial. Even though it's the week after thanksgiving the JBoss Community still has a bunch of interesting developments to report on.

 

Should we Remove MongoDB from Keycloak?

The Keycloak team are considering the removal of support for MongoDB backed KeyCloak servers. Among other reasons, they cite lack of support for transactional updates to multiple documents in MongoDB, as a major contributing factor. However, elsewhere in the JBoss Community there is work afoot to bring non-ACID transactional support to MongoDB. As is typical in the JBoss community, they are seeking feedback before taking the plunge. See this blog post for the reasons to make this change and instructions on how you can join the discussion.

 

Node.js DNS Module and Debugger Explanations

Lucas Holmquist continues his exploration of Node.js modules and features. This week he explains how the DNS Module works and how to use the Node.js debugger.

 

Improvements Around using Infinispan with Spring

If you are using Infinispan with Spring, be sure to read about the improvements the team are making around this integration.

 

How to run JBoss BPM Suite in a Container

In this post Eric Schabell explains how to run JBoss BPM Suite in a Container using either the Openshift Container Platform (OCP) or the Red Hat Container Development Kit (CDK).
