As September reaches its end, we give you more editorial leading with the welcome return of the JBoss Asylum podcast,  followed by an in-depth article from James Strachan on how to set up and use both Docker and Kubernetes, but, for once, from a point of view of a Java developer. And a busy one, with little precious time to lose on this...

 

Return to the Arkham Asylum

 

Arkham Asylum RollerCoaster

 

The JBoss Asylum podcast is back ! Well, it's back for what appears to be its now yearly release schedule JBoss Community Asylum - I git your flow. Whatever the release frequency is, we'll take it as this is still an excellent podcast to listen too ! In this episode, Emmanuel, Max and co took the time to revisit an interesting topic: workflow with git.

 

This has been the topics of many talks in the early 2010's - I know that for a fact, as many of my own talks were about that at the time - and it is very interesting to see what have come out it, several years afterward, now that the adoption of Git and Github, has become massive (at least in the JBoss ecosystem, if nowhere else).

 

And, of course, as always with git, the episode will reveal some nefty little nice tricks... Along with the return of a debate that never becomes old: tab vs space !!!

 

A Java developer guide to microservices with Docker and Kubernetes

 

James Strachan is one of core developer of fabric8, and thus a very busy person. However he took the time to write up this very nice guide : A busy Java developers guide to developing microservices on Kubernetes and docker - which covers, in a few words, how to setup and use both Kubernetes and Docker, but from a Java developer standpoint. If somehow, you managed to escape the Docker and Kubernetes frenzy up to this point (How did you managed do that ? Are you living on a rock in the ocean ?) this is a perfect article to catch up in no time...

 

Events - Microservices Journey with Apache Camel and Scotland JBUG

microservices+journey.PNG

 

Announced already a couple of weeks ago, the Microservices Journey with Apache Camel is happening next week. A friendly reminder, in case you happen to be around and available. And if you missed the latest session of the Scotland JBUG, Eric D. Schabell will catch you up with his Scotland JBug Recap - An evening of Cloud, Containers, BPM & more.

 

Google is drolling

 

Another Google Summer of Code just went by successful as always, and features among the most intriguing experiment, this integration between Drools & Minecraft ! An original one, to say the least, where the business engine is used to declaratively define the game's logic.

 

Tech bytes

 

First of all, the previous Google Summer of Code news was not the only news on the Drools front : an interesting article has also been released on: Improved container handling and updates in KIE Server. Go take a look ! On another front, Hawkular, Heiko took the time to write a nice summary on how the framework handles Computed metrics for HawkFX.

 

The Hibernate ecosystem is as always thriving and if you want to know more about it, just checkout this month's newsletter: Hibernate Community Newsletter 19/2016. Not far from the ORM business, lays the world of data virtualization, and its lead project: Teiid. The project has indeed a major change coming its way - albeit not technical: Teiid Licensing is going to change (following the trend of other JBoss project, to a more permissive license).

 

Let's go now to a completely different universe. If your Java is often flavored by some JavaScript on the side, you may find this article on Checking Dependencies with SZero quite interesting.

 

Last item on this section, an other interesting tutorial from Eric D. Schabell : Installing the Red Hat Container Development Kit 2.2

. Well, all of this should keep you busy for while, shouldn't it ?

 

Releases, releases, releases...

 

No releases this week !!! Incredible ! That's the first time, since I've started writing those editorial, that it happens ! Well, don't worry, they'll be back next week !

It’s been a crazy week for the Java Community as a whole with major announcements happening at JavaOne in San Francisco! Java turned 21 this year! Java SE 9 continues to move closer. Java EE 8, is, well, postponed. The Java community continues to thrive and push out amazing technology, and so do we here at Red Hat!

A number of announcements happened this week you’ll probably want to be aware of.

 

News

One of the largest announcements made, at least by Red Hat, was MicroProfile 1.0! A few months back, June to be precise, the MicroProfile was announced. Red Hat, along with IBM, TomiTribe, Payara, and LJC (and SouJava joined since) worked with the community to create a standard around microservices using Java EE. The 1.0 release of MicroProfile finished a few weeks early and there are six different implementations. Read more about MicroProfile at the release blog, or Mark Little’s recap.

 

Juraci Paixão Kröhling explained how to use Hawkular APM in a microservice architecture earlier in the week. His post is informative and heavy on the details and explanation. Head on over if you fall into this camp and are looking for answers!

 

This last one may make some of you a bit squeamish, you have been warned. As of Keycloak 2.2.0 the keycloak-server.json stopped being shipped. All configuration is happening within standalone.xml, standalone-ha.xml, or domain.xml. JSON is often a preferred format, but Stan Silvert explained why XML is better in this instance when he wrote about the demise of they keycloak-server.json a few days ago.

 

Releases

We’re always kicking out new releases of our software. Once again, this week was no different. Hibernate had a couple of releases this past week, ORM 5.0.11 and 5.1.2. Byteman has a 4.0.0-Alpha release which allows Byteman to be used on JDK9! Of course, it continues to work on JDK6-8, and there is one small issue, but read the blog for more information. Lastly, Keycloak 2.2.1.Final was released fixing an issue with the JavaScript adapter released in 2.2.0.

 

Events

Besides JavaOne this week, there were some other events we participated in, and some which are going to be happening!

Eric Schabell discussed Red Hat Forum going to Finland this year. If you’re in that area you won’t want to miss him talking about Open Source, Red Hat and change. There are also some other great speakers lined up for these Red Hat Forums in Europe.

 

To round out our week, Eric Schabell and Claus Ibsen talked about their talks from this week or a couple of weeks ago. Claus attended JDKIO 2016 in Copenhagen where he discussed Apache Camel and Java based microservices. Read about his trip, or watch the recordings in his blog post.

 

In London this week, Eric Schabell talked about private cloud at the London JBug. His slides are available for those interested.

Thanks everyone for making this another wonderful week in tech! Stay tuned for more software, talks, and information as time goes on.

Welcome to another Weekly Editorial! Everyone here at Red Hat Middleware has been busy to one degree or another, but we’ve still managed to get some work and releases done. To get things started this week, let’s talk about some upcoming events you’ll want to attend!

 

Events

In just over a week Java Developers from around the world will descend upon San Francisco for the annual JavaOne event presented by Oracle. Once again, Red Hat continues to deliver a number of quality presentations and topics ranging from React, microservices, testing, Java EE and others! In total, more than 20 presentations will be given by Red Hat engineers this year. Also, don’t forget to stop by the booth in the Exhibitor’s hall, we’re just to the right of the entrance. At the booth be sure to check out the two demo pods and the mini theater where you will be able to hear miniature versions of the presentations from our engineers. We’ll be running demos there as well talking about microservices, OpenShift and the new MicroProfile initiative. If for some reason you’re not able to attend or miss a session at the mini theater, don’t worry. You’ll be able to see them on developers.redhat.com, be sure to head over there and sign up for all of the latest on the Developer Program by Red Hat.

 

Happening next week is the Red Hat Forum in Zurich. Dimitris Andreadis blogged about this event. See him, Thomas Heute, and Hannes Sowa talk about Java EE, containers, and cloud environments. You won’t want to miss any of these events!

Books, Logging, Threads

Eric Schabell has been working tirelessly on his BPM book with Manning. The first four chapters are available via the Manning Early Access Program. Eric has a wealth of information about Business Process Management, and getting all that information in an easy to digest book form is excellent news!

 

Ricardo Hernandez explained centralized logging for Vert.x applications using the ELK stack earlier this week in a very detailed blog post including examples and a demo! If you’re using Vert.x and are looking for a centralized logging solution, look no further than his blog post for all the gory details.

 

Bela Ban talked about removing thread pools in JGroups 4.0. This will be a welcome change for those of us using JGroups as it means a smaller configuration, fewer threads, and overall lower latency. Be sure to read through it for all the information and how these changes may affect your application.

 

Releases

Along with all the already amazing content that has been produced this week, and conferences coming up within the next couple of weeks, there have been a number of releases of note as well. Each link details the release and the specifics:

 

Thanks for joining us for another JBoss Weekly Editorial! Have a great weekend and we look forward to seeing you next week!

For various reasons we appear to have missed a week of our Editorial and this week's edition is coming later than usual for which I apologise.  The good news is  we now have more articles to draw on so you are more likely to find something of interest to you

 

Hibernate News

 

Our first article comes from Mincong, an Engineering student from France who is working with the Hibernate team on a Google Summer of Code project.  Mincong has been working on an alternative to the current mass indexer within Hibernate using JSR 352, the Batching Applications API  now part of EE7, to take advantage of the batch tooling delivered within the platform.

 

Our next article is asking for your help to make a decision on the direction of Hibernate OGM. Hibernate OGM has been able to work with an embedded Neo4j instance for some time however the team would now like to add in the ability to work with a remote instance.  There are two options being presented, adding support for the Bolt binary protocol or make use of the REST API.  If you are interested in OGM then get involved and vote on its future.

 

We end this section with the latest edition of the Community Newsletter in which they highlight articles on using Java 8 Streams, the benefits of Repeatable annotations, defining Query Timeouts and many more.

 

Microservices

 

As part of a Google Summer of Code project working with the Vert.x team, Eric Zhao has been working on a set of blueprint tutorials designed to guide users through the design and development of message-based applications and microservices using Vert.x.  The blueprints cover many aspects of Vertx.x development as well as microservices patterns such as Service Discover, Circuit Breaker etc. and can be seen running on OpenShift.

 

If you are interested in using Spring Boot to implement Microservices then check out Christian's demos for creating a service and running it within Kubernetes.

 

Infinispan News

 

With the release of the C++ Hotrod Client you may now be wondering how to integrate Infinispan caching into  your application, if so then Vittorio can help through his example code  demonstrating how to set up the client, populate the cache and finally run queries against the data.

 

If you are using the Infinispan docker image then you have a number of options for how to configure the image depending on the environment within which you are running, for some advice take a look at Sebastian's article covering the choices you have.

Getting Started with OptaPlanner

 

OptaPlanner is a project  implementing a constraint satisfaction solver, an engine  using sophisticated optimisation algorithms to help you manage a limited set of constrained resources.  If getting started with this project appears daunting then Duncan has six steps you can follow to help you develop a solution  satisfying your problem.

 

Authenticating EAP Users using the Operating System

 

While EAP does not provide an 'out of the box' solution to integrate with your Operating System's authentication mechanism this is something that can be added in very quickly and easily.  If you are a user of Linux/Unix or Windows then Siddhartha demonstrates how  this can be solved through the integration of JPAM and Waffle with the EAP security domain.

 

Generating Reports from Windup

 

Marek demonstrates how to use the Windup migration tool to export its analysis results into a CSV format so  the results can be imported into spreadsheets tools such as LibreOffice.  Marek shows how simple this is using a JEE example application distributed as part of Windup so now you have no excuses for giving this a try .

 

JBoss Out and About

 

Andrew Block will be attending the annual APAC Red Hat Tech Exchange conference in Ho Chi Minh City, Vietnam, to present several talks on behalf of Eric Schabell.  The conference begins on September 4th and runs until September 8th.

 

Julian, Clement, Burr, Edson and Paulo from the Vert.x team will be attending numerous conferences over the fall, including JavaOne and Devoxx BE, to help spread the news about this fantastic reactive framework for Java.

 

Claus Ibsen will be attending the JDK.IO conference in Copenhagen to present talks on Apache Camel and  developing Java based microservices.  The conference runs from September 13th to September 15th.

 

New Releases

 

 

That's all for this week, please join us again next week when we will endeavour to resume our normal schedule.
