Weekly Editorial

190 posts

If you are not already on holiday, you'll probably be soon (or you are already back from them) - in any case, the JBoss communities are never on the break, and this week, last the ones before, comes a fair of exciting and interesting news (and yes, stuff about Docker).

 

Monitoring Wildfly and your Vert.x apps

 

In the last year, with the emergence of the DevOps initiative and the adaption of Java since the early 2000s, the topic of monitoring (and handling operation) of JEE server has been under an increasing focus. Especially because many administrators had an hard time grasping JVM related concept

and integrate the available JMX metrics inside their own tools (or scripts). However, if all metrics and operation on Wildfly

Monitoring DevOps Style With WildFly 9 And Jolokia ~ Enterprise Software Development with Java

 

Along those lines, the new project Hawkular, which aims at replace the previous RHQ as monitoring and operations managements tool for Wildfly, has made an interesting demo on Monitoring a Vert.x Application using Hawkular BTM, go check it out !

 

Data Virtualization and Hadoop

 

Kenneth Peeples, one of our very own Evangelist, has been diving deep into the integration between DataVirt  and Hadoop, in Connecting to Cloudera Quickstart Virtual Machine from Data Virtualization and SQuirreL. He also took the time to do a thorough inventory of supported environment and products in the latest version of the Data Virt: Tested Integrations for Data Virtualization.

 

Note that Data Virt is the name of the Red Hat supported version of Teiid. Whatever you read in those article obviously applies to the associated version of the community project Teiid.

 

On the applications side

 

Along the lines of the previous section on monitoring, the following article discuss how to configure a Vert.x Application and it is certainly worth the read ! And if you are not (yet) using Vert.x to develop your latest webapp, chances are you are still going to be deploying some (or more probably a lot of) Javascript. In this case, you'll be delighted to hear that Bower support is coming to JBoss Tools !


BRMS and jBPM -  Processes, Rules and Events for everyone !


BRMS and jBPM are all over the place, and, as you'll see in this section, and you are bound to find something here that interest you ! Obviously, the first item is this new book on the topic: Processes, Rules and Events: Book: Mastering jBPM6. Certainly an excellent starting point, wouldn't you agree ?

 

Then, if you are use of Fuse, you'll be delighted to read this new blog entry from Christina on Enterprise application architecture with JBoss Fuse and JBoss BPM suite.


If you read this editorial on a regular basis, you must be aware by now that Eric Schabell has published a lot of workshop around JBoss BRMS. Well, now he even show you how to use it to build your own workshop or event on JBoss BRMS Workshop in a Can Getting Worldwide Love !


Last, but certainly not the least, Drools & jBPM: Validation and Verification for Decision Tables Update

 

Arquillian

 

As always, the Arquillian ecosystem has come with his share of releases ! Please check'em out, as they are both adressing quite difficult (and crucial) topics :


Dockerland

 

It maybe Summer, but it's still 2015, and no week should go by without at least mentioning Docker ! Rest assure, our famous Arun Gupta brilliantly took care of that by discussing Kubernetes Design Patterns. Go read it, it comprehensive overview of the high concept of Kubernetes and how it would apply to your software architecture.

 

Decaf'

 

Quite unknown in the Java universe, the Red Hat Software Collections are very practical and provide an excellent environement for developers to work on. Last week article on Red Hat Developer Blog on Using Software Collections Toolset For Your Own Applications offers a nice overview if you wish to learn a bit more about those...


That's all for this week, please join us again for the next installment of the JBoss Editorial where we will endeavour to bring you more interesting articles written by members of the JBoss communities.

Welcome to another edition of the Weekly Editorial where we take you through some of the work that has been taking place within the community over the past week.

 

Kubernetes, Docker and Swarm

 

We begin this week's editorial by taking a look at a number of posts written by Arun, covering topics including Docker Compose, Docker Swarm and replication in Kubernetes.  His first post demonstrates how to set up a multi-container application using Docker Compose and Docker Swarm.  He follows this up with two posts discussing kubernetes and its replication controller, first demonstrating how the replication controller can automatically restart pods when necessary before moving on to discuss how to use the replication controller to modify the number of instances of a running image, scaling a cluster up or down.

 

Camel on WildFly

 

Marcus has written three posts this week discussing how to use Camel on WildFly to solve some problems you may face.  In his first post he demonstrates how to leverage Camel routes within JavaEE components through integration with CDI, JSF, JAX-RS and EJBs.  He then looks at how to use the HornetQ JMS bridge to integrate queues from a backend Weblogic server into WildFly, testing the integration using Camel, before ending the week by taking a fresh look at a demonstration written by Christina Lin and showing how the same application can be developed using JPA and CDI integration with Camel.

 

BRMS Goodies

 

This week has seen Eric provide updates to some of his BRMS goodies.  He began by providing an update to his BRMS Cool Store Demo, taking advantage of a number of the fixes that have gone in to JBoss BRMS 6.1.1 to showcase its features, and then followed up by introducing a canned version of a workshop that you are free to use with any audience, whether a JUG, JBUG, work group, a conference or any other.

 

Hello Vert.x

 

If you have already heard of Vert.x then you will know that it is a project that enables reactive applications to be developed, relying on event driven and non-blocking features to scale applications with minimal hardware requirements.  To help you get started with this we have two "Hello World" tutorials, the first demonstrating how to develop a Vert.x application using java and the second demonstrating how to develop a Vert.x application using javascript.

 

Visual Editor for JEE Batch

 

The tooling team have added a new visual editor to support JSR-352 batch files, an API that provides support for Batch applications within the Java platform.  The editor is now available in JBoss Tools 4.3 and Developer Studio 9 for you to try out.

 

Hibernate Search Roadmap

 

Sanne has recently spent time updating the roadmap for Hibernate Search and has now provided a summary of the major aspects currently under development, also including some information on the direction they wish to take with future efforts.

 

Camel In Action, the sequel

 

Claus and Jonathan are writing a second edition of their popular Camel In Action book, a major rewrite of the first one.  As well as updating many of the existing chapters they are including six new chapters covering many of the new features that have been introduced into Camel over the recent years.

 

Hawkular Alerts

 

Hawkular Alerts is a new project spawned out of the experience learned during the development of the RHQ project, providing  fast, scalable alerting as part of the Hawkular Monitoring project.

 

VDB Builder

 

The Teiid team are busy developing a more versatile VDB editing tool called VDB Builder, a command line tool allowing the creation, editing and management of dynamic VDBs and their content.  Their first milestone release is now available and is ready for you to start experimenting.

 

JBoss Out and About

 

Arun and Devoxx4Kids were recently seen in London at the Minecon 2015 convention where they were fortunate to present their Minecraft Modding workshop to approximately 200 kids.  The workshop was a success with many kids experiencing their first opportunity to develop software through extensions to a game they love to play.

 

New Releases

 

 

That's all for this week, please join us again for the next installment of the JBoss Editorial where we will endeavour to bring you more interesting articles written by members of the JBoss communities.

For those of you in the US reading this a day late ... Happy 4th of July

 

We've a lot to cover this week as despite the fact many people have been recovering from the hectic week at Summit/DevNation, life and work must go on! So for a start let's look at something not necessarily associated with JBoss: Minecraft. For those of you in the know, however, you'll understand that not only is Minecraft based on Java but it also relies on Netty! A while back we announced that we had joined the Devoxx4Kids community; well this weekend our very own Arun Gupta and his son will be running the Devoxx4Kids Minecraft Modding Workshop at Minecon in London (helped by yours truly!).

We all know that last week was Summit, but it turns out that a new conference was also kicked off in Barcelona. JBCNConf was attended by several of the Fabric8 team and Claus gives a great overview of what happened there. Which ties in quite nicely to the release of Fuse 6.2, which Christina writes about. As Christina states, one of the important new features is RBAC: "Another important new feature is the Role Base Access Control. Powered by JAAS implemented. Many enterprise needed this in real production environment, what this does, it authorized user's right on access the Fuse console, JMX, command line mode and the service allowed in OSGi." Claus also has a great article on getting up and running with Fuse 6.2 quickly.

 

Now of course we have the usual flurry of entries summarising Summit and DevNation. Including one from Eric with his usual BPM focus, Mark Proctor talks about his presentation (with more related here), Arun (again) has a nice piece on Summit with lots of photos, and of course there's the Summit Keynote demo to watch again!

 

Screen Shot 2015-07-03 at 11.20.50.png

Some releases to note include 0.1.0 of the Hawkular Business Transaction Management project, which Gary discusses along with how you can monitor SwitchYard applications with it. Hot on its heels is Heiko talking about the Alpha2 release of Hawkular. JBoss Data Grid 6.5 is out!

 

If you're a LiveOak fan then you should take a look at the latest entry from Ken talking about its future.

 

And last but by no means least, WildFly 9 Final is out!!

 

OK that's it for this week. And I'll be on holiday soon, so it'll be down to the other editors to take you through the summer

All the hard work preparing for the DevNation and Red Hat Summit has come to pay off as Red Hat wraps up Summit Week and DevNation also comes to a close.

redhatsummitattendees.pngThis week has been busy for alot of folks getting ready for DevNation and Summit.  With more than 170 sessions and labs, 8 keynotes, parties, and receptions, Red Hat Summit has something for everyone as shown in the infographic to the right. From business and technical sessions to hands-on labs to 1:1 conversations, there's something for each level of interest and need during Red Hat Summit. 


For Developers, in addition to Summit, this year's DevNation event will have four general sessions to capture our imaginations, inspire our work, and spark the conversations that move us forward. Our keynote speakers are ready to bring it.


devnation_250x250_blogbadge_joinme.png

Here’s what you can look forward to.

- Freedom of choice. With 5 tracks, including sessions, panels, and labs, learning opportunities abound. Or you can hang out in our developer zone and charge up on coffee and electricity.

- Freedom of speech. You don’t have to network, but if you do, you’ll never find a cooler group of people.

- “Free as in beer.” Can you really know what “free” means if you don’t have a free beer in your hand? (But seriously, we have a few fun social events planned, and the hops will be freely flowing.)

- Freedom to break and create. We’re going to hack like hell over 4 full days. We’re dedicating 2 evening events to it, and you might win prizes even into the wee hours of the next morning.

- Freedom to roam. DevNation is co-located with Red Hat Summit, so you don’t even have to leave the building to attend both conferences. Do both at once in the shared track.



Developer Position Available


The Fuse team is looking for an Eclipse Developer to primarily work on JBoss Tools Fuse tooling.

Mobile, Microservices, and More...

 


This week's Releases:

 

Infinispan 7.2.3.Final - A few bugs have been found and fixwd in the Infinispan 7.2 branch.

Drools 6.3 SNAPSHOT - The team has rewritten the internal parts of our code that deal with multi-threading to remove a large number of synchronisation points and to improve stability and predictability.

Wildfly Swarm 1.0.0.Alpha3 - The team has fixed some things, enhanced others, written some tests, and generally knocked it together a little sturdier.

Keycloak 1.3.1.Final Released | Planet JBoss Developer - The team has done alot of improvements with this release.

Arquillian Container Chameleon 1.0.0.Alpha2 - In Alpha1 the definition for the JBoss AS / WildFly containers were hard coded. In Alpha2 we’ve externalized the configuration.

Bean Validation TCK 1.1.4.Final - BVTCK-68, which is about the removal of two tests from the TCK which could not be tested in a portable manner across containers. Check out the issue itself for the complete story.

Forge 2.16.2.Final - JBoss Forge 2.16.2.Final is now available

As a late student sneaking into classroom, and pretending to have been there since the beginning, summer has suddenly rolled on Europe this week. However, despite the heatwave coming with it, the JBoss communities have been, as always, thriving and produced numerous releases and interesting content for you. So, if it's too hot to work, or if you wish it would be, maybe it's time to have an iced tea, sit back and enjoy a nice tour of what happened last week...

When Data Virtualization goes the NoSQL road...

 

As you may know, Teiid is a data virtualization solution, which allows you to abstract your numerous databases into one, both simplifying your applications developpment and enabling you to easily creates report spanning across various part of your company or organization. If you don't know anything about it, the project just released Teiid 8.11 CR1 so it's perfect opportunity to go check it out.

 

For people who already knows about data virtualization, quite focused on SQL storage, they often overlook the fact that Teiid can also access NoSQL storage such as Infinispan or MongoDB. And even bring some SQL capacity to such storage ! Look at this in details with Ramesh Reddy blog's entries an SQL on MongoDB using Teiid - Part 1 and SQL on MongoDB using Teiid - Part 2.

(sorry, I really tried to find a picture of Teiid Lizard eating mangos, but one must admit the internet still has its limits, so you got a well feed one instead)

 

Keycloak in real life

 

Nowadays no website is really secured without a proper authentification - as my friend François Le Droff and I have strongly pointed out during out talk on Java & Security at Devoxx France (in French, sorry). However, strong authenficiation generally makes a horrid user experience - expect if you smartly uses OAuth2. And if you wonder how to set that in place, look at this thorough demonstration using Keycloak to secure your services with OAuth2.

 

An other brilliant demonstration of Keycloak usefulness is this other explanation of how OpenShift UI Console authentication with Keycloak and OpenID connect together.

 

Hopefully those two description will convince you to give a serious at look at Keycloak, so if you happen to go to DevNation, don't forget to attend Enterprise security with Keycloak – from the intranet to mobile.

No Docker ? Seriously ?

 

Of course not ! This entry would not be a proper "IT related blog entry" without at least one entry mentioning Docker, would it not ? Well, don't worry, here it comes : Docker Compose on Windows with Python And Babon ! (Yes, just one, but a good one )

 

AeroGear and Feedhenry

 

If you are an aficionado of either AeroGear or Feedhenry, you'll probably be curious about this new post on AeroGear quick start push Templates,

which show both product can operate together quite nicely.

 

Evangelist's Corner

 

As always, our team of Evangelists have been tireless and produced quite a lot of interesting content for you to browse this week. First, Eric D. Schabell offers, yet an other follow up, to his JBoss BPM Travel Agency Demo adding modern BPM Data Integration to it, along with a peak of sneak preview of his submission for both NCDevCon and Red Hat Summit :

 

Then, Arun Gupta comes and discusses how to go from Monolithic to Microservices Refactoring for Java EE Applications,  whille Markus Eisele is tackling on an ever more challenging (albeit none technical) task in his 9 Ways To Stop Hurting And Start Helping Women In Tech.

 

Releases, releases, releases

 

Decaf'

 

With some many cool Java news, your blood is now filled with caffeine, your hands must be shaking like hell, and your heart is pounding. In short, time to switch to decaf' ! So, for a change, and a completly none Java related topic, take a look at this quite thorough and interesting description on Five different ways to handle leap seconds with NTP (if only to be able to clearly state why leap seconds is not an issue for your Java code ).

 

That's all for this week's spin through the JBoss world, please join us again next week when we will take you through more interesting and informative articles written by our communities. And don't forget to follow @jbossdeveloper !

Welcome to another edition of the  Weekly Editorial where we take a quick spin through the JBoss Communities and highlight some of the interesting work that has been taking place over the last week

 

Data Mapping within the Camel Editor

 

Strong data mapping tooling is a capability that has been missing from JBoss Tools suite for some time however a recent effort to improve the tooling has had this as its focus.  In the first part of a series to cover this work Brian introduces us to some of the underlying technologies that are being used within transformation, explains how to obtain the new tooling capabilities and finishes this first part by demonstrating how these capabilities are being integrated into the Camel tooling in order to handle data transformations as part of an existing camel route.

 

NoSQL with Hibernate OGM

 

In the third installment of the tutorial series "NoSQL with Hibernate OGM", Gunnar demonstrates how to use Hibernate OGM from within a Jave EE application.  This installment extends the entity models created in the previous installments and introduces additional functionality showing how to expose those models through JAX-RS endpoints.

 

Java EE deployment within Docker Containers

 

Interest in the containerisation of applications has grown over recent times with many of us exploring how this impacts the way in which  we package our applications and deploy them into production environments.  If you are still investigating this technology then you may find this post by Markus to be of interest, in which he covers some of the major advantages and disadvantages of this approach.

 

Type Functions within Ceylon

 

The Ceylon team have recently been experimenting with a new feature to introduce type functions into Ceylon, technically known as higher order generic types and higher rank generic types, and are looking for feedback from the community to determine whether this is a capability that should be included in the language specification and officially supported.  Gavin has a post covering the experimental feature, including a very good explanation of what is being proposed, and there are already some very good conversations happening within the comment section.

 

Dependent Joins with Teiid

 

If you have been using Teiid to join disparate data sources then you may have come across a number of scenarios where the Teiid planner cannot determine a good plan using statistical analysis.  If this is the case then Ramesh has an answer for you, introducing an optimisation that can be used to reduce the impact of your statements through the inclusion of hints.

 

Camel and IoT

 

IoT is garnering a lot of attention these days and, with its support for MQTT, the Apache Camel project is well placed to help provide solutions.  Claus has found one such project where Camel is being used to help gather air quality metrics from IoT devices all over France.

 

JBoss Out and About

 

With  Red Hat Summit  starting in a few weeks many people are busy preparing for their presentations or going through the Agenda to sign up for interesting sessions.  If you are attending Summit, and interested in BPM, then you may wish to check out a couple of labs being hosted by Eric Schabell and others, Racing Camel with BPM and JBoss Fuse and Choose Your Own Adventure with JBoss BPM Suite.

 

New Releases

 

 

That's all for this week's editorial, please join us again next week when we will bring you more exciting news from our communities.

Another week in JBoss. It's been pretty busy and everybody went straight back to work from a long vacation weekend. Now we're gearing up for Summit and DevNation. So, let's see what happened over this last week:

 

Microservices - Container, Orchestration and More

We are hosting a full day event, in central London on June 11th 2015, where we will present the latest stuff we hack on our day time job - that is fabric8, hawtio, kubernetes, openshift, Camel, and more. Eric Schabell published a Microservices Migration Story with JBoss BPM Travel Agency. And you got to learn how to secure microservices with Keycloak. James Strachan showed you what Kubernetes means for Java Developers. A lot more hands-on is Thomas' post about Installing Red Hat Container Development Kit on Mac OS X. He also taught us how to use the Docker Client with the Red Hat CDK. Our own Mark Little published a nice peace on InfoQ about Microservices Premium.

 

Interesting Picks To Read

Asciidoctor encompasses and builds an ecosystem around Asciidoc for writing documentation, and well, writing anything. If you want to host your own blog, documentation site, book, ect., Asciidoctor would be an excellent choice. If you want to do that in OpenShift, that is what this post going to help you with. If you're into Hibernate, make sure to check out the great content on Vlad's blog. He recently wrote about How does Hibernate READ_WRITE CacheConcurrencyStrategy work and has a ton of other great tutorials and Hibernate details over there.

dataintegration.png

Microservices and Integration

 

  • Syed Rasheed wrote an excellent article on JBoss Integration Products, explaining Application Integration and Data Integration, Ultimate Guide: When to use which JBoss Integration Products.  In The Bottom Line he indicated that In the end, application integration platform like JBoss Fuse are best suited for the functional integration of independent applications to implement a multi-step business process. Data virtualization platforms are best suited for the creation of data services where one is attempting to present a holistic view of the business data for analysis or operational visibility. Both technologies have different primary use cases and they are not interchangeable, however they can be used together.
  • Christina Lin continues her Microservices migration story with the Integration Demo Series with Fuse and BPMS. 
  • Stian Thorgersen discussed Securing Microservices with Keycloak and OpenID.  As microservices is all about having many smaller services each that deal with one distinct task the obvious solution to security is an authentication and authorization service. This is where Keycloak and OpenID Connect comes to the rescue. Keycloak provides the service you need to secure micro services.
  • Mark Little highlights XA and Microservices. I'm not suggesting that XA doesn't have a role to play within microservices and between microservices. At least in the short term it most definitely does for some (small) set of applications. But really when I'm suggesting transactions have a role I'm looking well beyond XA.

  • Red Hat JBoss Developer Studio, built on the popular Eclipse-based developer tool JBoss Tools, allows Eclipse Java users to develop applications for Red Hat JBoss Middleware, such as Red Hat JBoss Enterprise Application Platform and JBoss Fuse.
  • Red Hat Developer Toolset, based on Eclipse Linux Tools and CDT, allows C/C++ developers to quickly build Red Hat and Fedora based solutions.

Red Hat also plans to join the Eclipse Internet of Things (IoT) Working Group, an open source community for the Internet of Things. Red Hat's participation in the Eclipse IoT community will focus on enabling enterprise middleware for IoT solutions.


 

Introducing to Vertx.3

 

 

Thanks to Tim Fox to take the time to communicate around the new Vert.x 3 architecture. This v3 will introduce lots of changes and improvements and should become 3.0.0-final release on 22 June.

A new web site has been created to support this platform and is already available : http://vert-x3.github.io/.

 

One of the big things in V3 is Apex which is a set of components for building webapps with Vert.x and is already proving to be quite popular even before the final release. More info about Apex can be find on the web-site.

You can use Apex for all sorts of web applications - e.g. "traditional" server side rendered web apps, client side rendered web apps, but a key focus is for lightweight HTTP/REST micro-services.

Apex has built in support for content negotiation and various other features -most of things you'd find in JAX-RS, but 100% async, and usable from any of the languages that Vert.x supports.

 

We've also made great efforts to make V3 super embeddable and it has a minumum of dependencies. Here's a Maven hello world app:  https://github.com/vert-x3/vertx-examples/tree/master/maven-simplest

 

V3 also aims to create a full async (where possible) stack, so we've also included components for database connectivity (JDBC, Mongo, MySQL/PostgreSQL, Redis), email, messaging (AMQP 1.0, RabbitMQ), and we hope to increase the number of components over time.

 

V3 contains some sophisticated code generation technology which means we only have to maintain Java versions of our APIs and examples, the other language APIs, documentation and examples are auto-generated at build time from the Java stuff. This makes it much easier to maintain than Vert.x 2 where we manually had to maintain each language API.

 

V3 also has some pretty cool Rx support (https://github.com/ReactiveX/RxJava) - if you're not familiar with Rx, it's all about doing operations on asynchronous streams of data using functional style operations. It's one way of mitigating against "callback hell" which can occur when using event based APIs. We provide "Rx-ified" versions of all our APIs - so you now have a choice of whether to use the standard callback-based API (node style) or an Rx-style version.

 

V3 also reactive streams support - this is about interoperability with other reactive systems (e.g. Akka, project reactor etc) !

 

 

Hot Stuffs of the week

 

 

  • IoT Eclipse Gateway & Apache Camel

 

OSGI is not death and looks like a promising technology for the IoT Gateway platform developed by Eclipse under the code name Kura for the field devices (RaspberryPi, ...). By combining this platform with the Integration Java Framework Apache Camel and its messaging routing engine, we expend the possibilities to interconnect everything, everywhere.

Thx to Henryk Konsek to record this video and share its presentation.

This week editorial is eventful indeed, as it features a lof of events being either announced or launched in the last days. But rest assure, even if you can not attend any of those, whether its DevNation or Bela Ban's JGroups Workshop, there is also a bunch of interesting articles and news for you ! Maybe reading and them and discovering some new, cool technologies, would not the worth thing to do on Labor Day tomorrow ...

 

Eventful

 

Welcome Google Summer of Code Students 2015 to JBoss ! If you consider attempting the now famous GoSC, please checkout the projects the JBoss Community is proposing - you may find the best topic for you !

 

gsoc2015-300x270.jpg

 

With those events coming up soon, we've been mentioning the Red Hat Summit and DevNation quite a lot lately. But that a very special news we have about those this week : the Devoxx4Kids CFP has been launched ! So, if you plan to go to any of the previously mentioned events with your family, give your kids a real threat and register them (or, even better, consider applying to the CFP).

 

Devoxx4Kids-logo_0.png


Regarding, the DevNation and Summit them self, if you are interested by Processes, Rules and Events (so jBPM), you'll see that already quite a lot of tracks covers this topic.

 

 

 

 

 

 

 

At last, but certainly not the least, Bela Ban, leader of the JGroups project - on which is built Wildfly clustering and Infinispan, has announced a couple of JGroups workshops in New York and Mountain View. This is would a perfect opportunity to learn from "the master" directly but also deep-dive into advanced features or simply recent ones.

 

In Depth...

 

If you have a day off tomorrow, maybe it's time to seat back and catch up with some reading. And this week, the JBoss Community has been quite prolific ! First is our very own Mark Little, who took the time to wrap up its own thoughts on Microservices and events. Next is a sum up from Thomas Qvarnström and Markus Eisele on their recent joint webinar on Continuous Delivery with Docker Containers and Java EE. If you are not done after those two, or just craving for something else, Kenneth Peeples opened - and discussed, an intriguing question : What are the benefits of Node.js ?


The previous article were quit high level, on might say, but if you may desire something a bit more practical, so why not jump into Integration Testing JBoss Fuse 6.x ?

 

Release or die !

 

Well, it's certainly not true that some of us would die if nothing was released, but it is also a fact that JBoss Community always opt to release anyway   - so here are the major releases of last week:

 

Evangelist's Corner

 

As like every week, our Evangelists have kept publishing new cool contents to the JBoss community, such as Eric D. Schabell's Slides from Online PEX Webinar - A Guide to Modern BPM Tools, or the new chapter in the When xPaaS meets DEVOPS (Part Three) series from Christina Lin.

 

Decaf'

 

I like to always finished this editorial by looking a bit outside the Java universe, as only very few Java program run only on their own, so it is always to keep one mind open. OK, so maybe this time I've been a tidbit nostalgic, but I must admit this article on Remote debugging with GDB on the Red Hat Developer Blog caught my eye.


It reminded the time of master degree, when I was experimenting C programming on Unix system, and programming was still a new and simple world, simple as a "hello the world" program. (Spending part of my week fighting my IDE and trying to get my stuff to build properly may have been the source of such nostalgia ! ).

 

That's all for this week's spin through the JBoss world, please join us again next week when we will take you through more interesting and informative articles written by our communities.

Welcome to another edition of the Weekly Editorial.  Sit back, grab a drink and relax as we take you for a spin through the projects that make up the JBoss Community.

 

When are Champions No Longer Champions?

 

When they are Heroes of course.  Last month we announced the creation of a new program to recognise those community members who are passionate advocates of JBoss technologies.  This program was launched under the name JBoss Champions but is now called JBoss Heroes.  Do you know of any heroes?  If so get nominating!

 

EAP 6.4 is Out

 

JBoss EAP 6.4 has just been released with many enhancements and new features, the biggest being the inclusion of Java 8 amongst the list of supported virtual machines.  This is a timely release, as Markus points out, as Java SE 7 will no longer be receiving updates from Oracle after this month.  Arun has provided a summary of many of the new features and how to obtain the binaries.

 

DevNation

 

The DevNation conference is taking place in Boston this year, from June 21st to June25th, with early bird pricing finishing today (24th April).  The conference agenda and featured speakers have now been announced so what are you waiting for?  This is a great opportunity to meet many of the core engineers in person, perhaps over a beer, and talk about anything.  The conference is also hosting a Devoxx4Kids event with submissions for this event remaining open until May 7th.

 

JavaOne Submissions

 

JBoss projects are usually well represented at the JavaOne conference in San Francisco with many core developers and community members giving presentations on many topics.  Our very own Markus Eisele, who is again part of this year's program committee, has some great advice for those who are still considering a submission.  Hurry up though, the Call for Papers closes on April 29th!

 

The conference is also working with the Devoxx4Kids organisation to run a special track aimed at children, submissions for this track are handled through the same Call for Papers process.

 

Docker, Docker, Docker

 

Docker is a technology that is generating a lot of interest within JBoss with many of our projects and products already creating dockerised versions so that you can focus more on how they are used rather than how they are configured.  Last week's release of Docker 1.6.0 brings numerous improvements, not only to the docker client but also to a number of other docker projects.

 

In Tech Tip #84 Arun introduces  a number of these changes while concentrating primarily on the changes that have gone in to Docker Machine.  He then follows up with Tech Tip #85 where he demonstrates how to orchestrate a cluster of containers using Docker Swarm.  Markus also covers some good news for those who work on Windows as this release also sees the introduction of the first Docker Client for Windows.

 

Kerberos in Keycloak

 

The release of Keycloak 1.2.0.Beta1 introduced support for login using Kerberos tickets through SPNEGO (Simple and Protected GSSAPI Negotiation Mechanism).  Marek has written an article describing the flow of a typical authentication scenario and explaining the steps required to set up the Keycloak provider.

 

Asynchronous Continuation in jBPM 6.3

 

The 6.3 release of jBPM will introduce a lot of changes however there is one feature that stands out having been requested many times, asynchronous continuation.  What is asynchronous continuation?  How can you make use of this features within your business processes?  Let Maciej show you how.

 

Visual Data Transformations

 

Keith Babo, of SwitchYard fame, has been working hard over the last eight months leading a team tasked with developing visual tooling in support of data mapping.  Claus has recently taken a look at their work, has some advice for how you can get started with their tooling and has provided links to some videos covering the various mapping styles they currently support.  Well worth some of your time!

 

JBoss Out and About

 

 

New Releases

 

 

That's all we have for this week's Editorial, we hope you have found something interesting to investigate and hopefully something that you feel you can contribute to.  Join us again next week when we will bring more news from around the JBoss Communities.

Another busy week is almost over. Time to wrap it up with the weekly editorial post. Get a #coffee+++ and enjoy the weekly recap.

 

Microservices and Container Still All Over The Place

Mark Little had a few conversations with different people recently on the subject of Transactions and Microservices and he put down his thoughts. While Arun added another angle to the discussion with the Microservice Design Patterns that he published. And even I got caught by the Container and Microservices hype and talked to Alex Soto in a new edition of the Developer Interview (#DI17) series about Arquillian, Docker and Testing In Containers.

I gave a talk at the Virtual Java User Group about how to architect large enterprise java projects which also talks a lot about all of this.The Keycloak team was playing around with OpenShift v3 and made it run there with Kubernetes.

 

DevNation Is Getting Hot

%7B4df908d9-becb-4bce-a05b-b67b674ce306%7D_devnation_emailheader_anopensourceconference.pngWe're just a few days away from having the complete schedule posted and the activities are winding up. A first introductory interview with our first keynote speaker, Venkat Subramaniam was published this week. If this isn't exciting, there's still some time left to get an early bird discount on DevNation tickets.

At DevNation, you’ll find a mix of: Technical sessions, Hands-on labs, Birds-of-a-feather panels specifically for developers, Late-night hacking events, A shared Summit-DevNation session track, Access to select Summit events.

This week has seen a lot of activity around DevOps and microservices. I'll shamelessly start with plugging a few things I've written on the subject, such as how you should look at microservices and Linux containers (such as Docker) for the natural unit of failure within a microservices environment:

 

"If you are building multiple microservices, or using them from other groups and organisations, within your applications or composite service(s), then do some thinking about how they are related and if they should fail as a unit then pull them together into a single image."

 

I also wrote an addendum to that article the other day just to make it clear that whilst containers such as Docker are useful, their neither necessary nor sufficient for microservices, especially in the Java world:

 

"If you're thinking about developing microservices in Java then you don't have to worry about using Linux containers: your unit of failure is the JVM. Start there and built upward."

 

I also wrote about how state can be handled with microservices, especially in a DevOps/cloudy environment where Linux containers are used and typically assumed to me immutable. Hopefully people find these articles useful - I certainly found them fun to write. Then in a semi-related article, Eric wrote about Docker and integration/BPM projects - lots of nice demos there! Everyone is looking at Linux containers/Docker these days, including the Keycloak team where Marko wrote about clustering recently.

 

Now some of our projects and products that are at the forefront of the things we're doing around microservices and DevOps are Fuse, Camel and Fabric8. Christina wrote about how to (lazily) create an offline repository. Christian took time to write generally about Enterprises and Microservices (part 1), but also how to do continuous delivery with Fabric8 v1. Claus has written a great "getting started with Fuse" article, so check it out if you're new to Fuse. Marek has written an entry on securing Fuse and Hawtio applications with Keycloak, which is a critical requirement for enterprise deployments.

 

In other news Kenny mentions the upcoming Red Hat virtual event Building Data-driven Solutions for the Internet of Things on April 23 at 11 a.m. (EST) / 15:00 (GMT). Sign up now! And the Arquillian and TorqueBox teams release new versions - 1.0.0 Alpha 5 (Docker extensions) and 3.1.2 respectively.

 

OK that's it for this week! Onward!
