Today, Red Hat released new versions of the following: Red Hat JBoss Developer Studio 10.2 Red Hat Container Development kit 2.3 Red Hat Development Suite 1.2 Here's a listing of the new features: Here are some of the new features in JBDS 10.2: Forge Tools. New Menu in Forge Console view to trigger the Command Selection Dialog. Common namespace is now...

Introduction Enabling SSL/TLS in a Fabric is slightly more complex than securing a jetty in a standalone Karaf container. In the following article, we are providing feedback on the overall process. For clarity and simplification, the article will be divided into two parts. Part1: The Management Console Part2: Securing Web Service:including gateway-http For the purpose of this PoC, the following environment will be used. Environment Host fabric1.example.com (192.168.56.1), localhost MacOS Host fabric2.example.com (192.168.56.101), RHEL 7.2 Virtual Box VM Host fabric3.example.com...

You’ve heard that .NET has gone open source. You’ve also heard that it has gone cross-platform. And you’ve even heard that Red Hat is shipping a supported version of .NET on Red Hat Enterprise Linux. So maybe you are thinking to yourself, “wow, this is fantastic! I’m going to copy these EXEs and DLLs of my .NET application over to my Red Hat machine and run them!” Well, unfortunately, it’s not going to be quite that easy. At least not...

Welcome back to a new episode of the series: "Unlock your [….] data with Red Hat JBoss Data Virtualization." Through this blog series, we will look at how to connect Red Hat JBoss Data Virtualization (JDV) to different and heterogenous data sources. JDV is a lean, virtual data integration solution that unlocks trapped data and delivers it as easily consumable, unified, and actionable information. It makes data spread across physically diverse systems — such as multiple databases, XML files, and...

You may have seen (or maybe missed) that in 2017, DevNation will be folded into Red Hat Summit 2017. The CFP deadline has been pushed back to December 16, so I look forward to seeing your submissions for application development! Speakers: submit your Application Development proposals today! Submit your proposal on the Summit CFP site [1] and tag it with the primary theme of Application Development. We’re interested in advanced technical topics of all developer-related topics, but especially looking for...

Introduction Kompose is a tool to convert from higher level abstractions of application definitions into more detailed Kubernetes artifacts. These artifacts can then be used to bring up the application in a Kubernetes cluster. What higher level application abstraction should kompose use? One of the most popular application definition formats for developers is the docker-compose.yml format for use with docker-compose that communicates with the docker daemon to bring up the application. Since this format has gained some traction we decided...

Fedora users seeking help on installing Container Development Kit (CDK), here is how you can install CDK 2.2 on your Fedora 24. These same steps can be used for CDK 2.3 too. CDK provides a container development environment, to build production-grade applications, for use on OpenShift. The installation of CDK 2.2 on Fedora essentially involves the following stages: Setting up your virtualization environment You need to first install the virtualization software, in this case, KVM/libvirt, and then proceed to install...

The Kubernetes client package for Go provides developers with a vast range of functions to access data and resources in a cluster. Taking advantage of its capabilities can allow the opportunity to build powerful controllers, monitoring and managing your cluster, beyond the scope of what is offered by stock OpenShift or Kubernetes setups. For example, the PodInterface allows you to list, update, delete, or get specific pods either by namespace or across all namespaces. This interface is complemented by similar...

If you're a regular on this blog, you're probably well aware of Red Hat's efforts in improving the Eclipse IDE and of the rise of Language Servers Protocol to develop common developer tools. Red Hat fully jumped on this opportunity to better factorize and share language-specific logic which is very likely to benefit to multiple editors, IDEs and languages at once. It also better separates the concerns of what an editor or IDE is supposed to do (text edition, integration...

One of the main principles of microservices is to be independently deployable. As a consequence, Microservices development and operation tend to be much more complex than a Monolith because of their distributed nature --- if your IT team has not moved out yet from its silos and has adopted DevOps practices, the operations team will not really understand why they have to deploy hundreds of independent software pieces in opposite to the "good old monolith". "You need a mature operations...

Part 2: How to Setup Jenkins to build iOS .ipa and run unit tests. A robust and agile mobile application development environment requires continuous integration and delivery. It also requires an integrated and automated unit testing process that helps bring applications to market successfully. This two-part series details my work done at Red Hat Open Innovation Labs and as a Mobile Technical Account Manager to capture these mobile innovations in a useful, repeatable way. In part one of this two-part...

Microservices are currently enjoying immense popularity. It is rare to find a tech conference without at least a few mentions of them in corridor conversations or titles of talks, and for good reason: microservices can provide a path to better, more maintainable, higher quality software delivered faster. What's not to love? Of course there are the "negatives" and details in the implementation of microservices that can trip up even the most seasoned architect-developer, but at the same time we are...

The world is moving to microservices, where applications are composed of a complex topology of components, orchestrated into a coordinated topology. Microservices have become increasingly popular as they increase business agility and reduce the time for changes to be made. On top of this, containers make it easier for organizations to adopt microservices. Increasingly, containers are the runtimes used for composition, and many excellent solutions have been developed to handle container orchestration such as: Kubernetes/OpenShift; Mesos and its many frameworks...

Cross language development in one project In this tutorial style article I'll discuss how to configure Eclipse for Java Native Interface (JNI) development based on a sample project that you can copy and modify. I.e, you can have a single project that can be both Java and C at the same time, and support a full code navigation and debugging of both languages. This article is focused on the configuration of Eclipse rather than explaining JNI itself, however there are...

Node.js is a JavaScript runtime built on top of Chrome's V8 JavaScript engine. It is highly event-driven, and leverages non-blocking I/O model that makes it lightweight, efficient, and incredibly productive to use. It's that last bit, "productive", that I want to focus on today. One of the things that i feel makes Node(and NPM) so great is the ease in which you can add and use third-party modules. As most node.js developers know, to start using an external module, you...

The recommended steps for setting up the Red Hat JBoss Developer Studio (JBDS), on all supported platforms, are found here. The instructions are pretty straight-forward and it is enough to get started right away - as long as you have a suitable java SDK installed on your machine. However, if I go along that path, I would later have to deal with the Java SDK updates to go along with the compatibility of the existing tools. Eventually, I may end...

James Kirkland is one of the architects involved in the new open source Kapua project on Eclipse.org. In this blog post he discusses how innovation happens when industry leaders collaborate to make their customers successful. Over the years, I’ve seen the beginning of a lot of open source projects, but the thing that excites me about the new Kapua project is that until now Eclipse IoT has been a set of individual projects that didn’t interrelate or even interoperate.
