"There is already a command line for it, why can't my favorite editor support this language?" As a developer, you're probably familiar with this sentiment, and in reality t here has never been a better time to be a software developer. Developers have access to a growing list of languages, frameworks, libraries, and technologies that can help them solve the problems they are tasked to tackle. However, the abundance of choices often hinders the ability of Integrated Development Environments (IDEs)...

We are pleased to announce the availability of OpenJDK 8 for Windows. OpenJDK is a fully open-source implementation of the Java SE specification. It is comparable in performance to Oracle and IBM JDKs. Red Hat distributes and fully supports OpenJDK in Red Hat Enterprise Linux 5, 6, and 7, for use with all Java applications. Red Hat has also taken on the role of supporting OpenJDK beyond the public EOL, and is the global maintainer for OpenJDK 6 and 7...

We are proud to announce the release the Red Hat JBoss Developer Studio 10.

In a world where agility matters, the pursuit to reduce wasted time in environment configurations is apparent in many technologies. Some techniques, such as Virtual Machines, that enable distribution of pre-configured images have existed for decades, while others like Linux containers are more recent. Even platforms like Java allow developers to package all dependencies, resources and configuration files in single JAR (Java Archive) file. What started initially as way to have executable Java classes in Java SE (Standard Edition), has...

At Red Hat, we all love playing with new technologies, and sometimes we find gaps that haven't yet been filled. I want to take a few minutes to share a personal project I've been working on in my spare time. It is a native C++11 add-on that allows you to run a JVM in Node.js, giving access to the mature Java ecosystem of libraries and frameworks. Motivation I just wanted some mature PDF library in Node.js, like iText , PDFBox...

Ready to develop container application in just over 4 minutes? Since I started playing around with OpenShift in its various forms, such as Online with cartridges and then later as containerized images, nothing has gotten me more excited than the availability of the Red Hat Container Development Kit (CDK). This kit has made it possible to easily gain access to a full, product based installation of OpenShift as you would interact with it in application development in just minutes. While...

Microservices are everywhere nowadays, and so is the idea of using service choreography (instead of service orchestration) for microservices interactions. In this article I describe how to set up service choreography using ActiveMQ virtual topics, which also enables scalable event based service interactions. Service Interaction Styles There are two main types of service interaction: synchronous and asynchronous . With synchronous interactions, the service consumer makes a request and blocks until the operation completes and a response is received. The HTTP...

Logging is an ubiquitous need in any production quality application, and one common scenario is to log the active (logged in) username, or to log the user and order IDs for customer order event details. This is typically done to create an audit trail so that issues can be more easily traced should something go wrong, but there are any number of reasons why you might decide to create a custom log. Mapped Diagnostic Contexts (MDCs) in Apache Camel are...

At Red Hat Developers, we're working to create a new breed of developer community - one where its participants Learn, Code, and Share together. As part of the process, we're publishing information that you find helpful, interesting, and things that generally make you awesome, feel awesome, and inspire you to do awesome things. (That's the goal, anyway.) One thing you might not know, is that most of the articles that get published here are actually contributed by our community members...

Recently I've been looking into different UI tech in use for apps built on top of Red Hat middleware, and I've discovered that many of Red Hat's products use PatternFly (in differing capacities) for their administrative UIs. PatternFly is "A community of designers and developers collaborating to build a UI framework for enterprise web applications." (from the website). There are also components, directives, etc, for AngularJS projects (which I really like). This sounds awesome, particularly because I'm a terrible designer...

I've been working with some of our teams recently on microservices and how we can assist our customers and communities with best practices and recommendations, whether they're Java EE developers, Vert.x coders, writing Node.js applications or something else. If you've read any of my previous articles then you'll know I have a few thoughts on microservices , and yet there are many things I still feel I need to get straight in my own head. That's why I love talking...

The classic 1984 movie Ghostbusters offered an important safety tip for all of us: " Don't cross the streams. " - "Why not?" - "I t would be bad. " - " I’m fuzzy on the whole good/bad thing. What do you mean, 'bad'? " - "Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light." - "Right. That’s bad. Okay. All right. Important safety tip. Thanks..."...

Recently, I have been hearing a lot of debate around whether it is worth someone's time to learn OSGi. Doing a simple Google search on "OSGi usability" returns results filled with phrases such as "not easy to use", "unproductive", "developer burden", and "going away". However, you will also find that it solves a lot of common issues in the JVM, particularly issues around class loading. So is learning OSGi worth your time? What is OSGi? OSGi is meant to solve...

The .NET framework is a relatively young technology when compared to the rest of computer science history, but as it turns fourteen this year, we can look back and see a long-standing record of innovation, developer productivity, and more recently a refreshing open-source mentality from Microsoft that has resulted in the first ever release of (the official) .NET framework in a Linux distribution. .NET is a development platform that includes several programming languages, notably C# and Visual Basic, and the...
