Red Hat JBoss Fuse is an open source, lightweight and modular integration platform that allows you to connect services and systems across your entire application portfolio. And if you're familiar with Fuse, you're probably familiar with the Fuse Tooling that comes with Red Hat JBoss Developer Studio. As I mentioned in an earlier post, the 8.0.0.Beta2 version of JBoss Fuse Tooling is now available. Apart from the diagram tooling rework, there is yet another new, awaited feature. You can find...

If you are a developer working on integration projects with JBoss Fuse, you'll be happy to hear that the Fuse tooling has recently been reworked to provide a brighter look and feel, a more sensible, approachable automatic layout. The work is still in progress, but already available in beta. It can be installed into the new JBoss Developer Studio version 9.1.0.GA. To check out the latest features, please install the latest JBoss Developer Studio (available here). Then follow the steps...

Tell the greater open source community where you are with IoT: investigating, planning, developing, or deploying. The IoT Developer Survey 2016 is sponsored by the Eclipse IoT Working Group, IEEE IoT Initiative and the AGILE Project. This is the survey's second year. Last year's survey found that leading programming languages were Java, C, and JavaScript. Key standards were HTTP, MQTT, and Linux. And 80% of companies responded were using open source in their IoT projects. Check out last year's survey...

If you're attending EclipseCon NA in Reston, Virginia this week, be sure to find these Red Hat sessions: TUESDAY Docker, Vagrant and Kubernetes walks into an Eclipse'd bar, by Max Anderson Grand Ballroom AB - Tuesday, March 8, 2016 - 11:45 to 12:20 Abstract: Today's software industry is booming with tools like Docker, Kubernetes, Vagrant and more to enable faster turnaround times via virtualization. How does Eclipse the IDE deal with that ? Can it deal with it ? How...

Vagrant gives developers a uniform way of configuring their virtual environment, regardless of the underlying hypervisor chosen (eg. KVM/QEMU, VirtualBox, VMware, Hyper-V). It's also available for Mac OS and Windows making it easier to run virtual Linux environments from these platforms. Today we'll be creating a simple virtual machine, using the Eclipse Vagrant Tooling plugin. This will be shipping as part of the Linux Tools Project 4.2.0 release (along with the Docker Tooling). The Vagrant tooling is targeted to make...

Now entering it's third year, the Red Hat Developer Toolset (DTS) is once again available for beta testing of a new point release, version 3.1. If you are unfamiliar with DTS, see Matt Newsome's (engineering lead) original introduction. Red Hat Developer Toolset 3.1 includes the latest, "stable open source C and C++ compilers and complementary development tools. Bridging developer productivity and production stability, Red Hat Developer Toolset 3.1 Beta is available through the Red Hat Enterprise Linux Developer Program and...

Lately I've been busy working on an Eclipse plugin that will support a wide range of docker functionality. Some of that has involved looking at some docker client libraries, figuring out how it works in one implementation, and seeing how this can be ported to other implementations. While the Docker Remote API is well documented, it can still be tricky to get things right. When I'm debugging some failed interaction, I've found socat to be very useful. Let's say we...

"Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees" -- Clean Code We spent 10 times more time reading code than writing it. Thus keeping code clean is essential for maintainability and company growth, but doing it by hand can be tedious. Let's take a look at some of the clean code practices and how we can use Eclipse to re-factor code faster. Change inline comments to sub method calls...

Last time we discussed de-duplicating some code. Today let us look into the effectiveness of refactored code, Java 8 support and moving/renaming code. But hold on, aren't method calls expensive? I took a course on compilers in University and did some research on the matter. In 1996 Java in-lining might have made sense. But nowadays the overhead that methods generate is relatively negligible, also the JVM is quite smart in optimizing bytecode by in-lining methods that make sense to in-line...

Tell us about your Eclipse usage

Do you have a Java application that runs fine at first but slows down after a while, or it runs fine for a small number of files but performance degrades for large number of files? Maybe you have a memory leak. About When fixing memory leaks; If someone were to ask me: "If you knew back then what you know now, what would you tell yourself?". Well, I would say..... Target Audience While in general the approach described in this...

Eclipse EGit plugin allows one to perform most every day git operations through the gui. (e.g commit with a sign-off/gerrit ID. View history, hard-reset, difference comparisons, Stashing, branching, etc.. ) The main advantage is that it makes some operations faster than through the command line, (e.g one doesn't have to type in file names or copy commit-id's). Egit is only a thin layer on top of git itself. So it does the same git commands underneath. Compatibility Linux/Windows/Mac. Already available...

The introduction of Eclipse Kepler (4.3.0) into the Developer Toolset 2.0 (DTS) not only brings the latest and greatest of this development environment, but many different features provided as plugins. For some, their purpose may not be immediately clear from their name, so let's quickly go through the list of Eclipse plugins shipped in DTS 2.0. JDT (Java Development Tools) Possibly the most well-known plugin for the Eclipse IDE. Create, manage, develop, test and debug your Java projects. The various...

One of the new features for the Developer Toolset (DTS) 2.0 is Eclipse 4.3.0 (Kepler). Aside from various performance improvements to the base platform since Eclipse 4.2 (Juno) a lot of other plugins are being shipped to make life easier for development. The C/C++ Developer Tooling (CDT) is a plugin used to develop, build, run, and debug C/C++ applications in Eclipse. It has support for various toolchains, Makefile/Autotools projects, static analysis, and easy navigation of a code-base thanks to a...

Red Hat intended for developers to integrate Developer Toolset 2.0 (DTS) and Red Hat Software Collections 1.0 (RHSCL). As you may not realize, inside the DTS is a copy of Eclipse and you can use that with any software collection. In other words, you can use PyDev, with the Python 2.7 Software Collection from RHSCL in the Eclipse from DTS. Let's find out how. First, let's make sure you have the right repos, [lwhite@lwhite-laptop ~]$ sudo yum repolist Loaded plugins...

As I've been using Git, SVN (with git-svn) and Hg for quite a long time now, I've adapted my way to handle the local repositories created with those tools. Especially, I quickly found out that it is quite crucial to separate those repositories from your IDE workspaces. Some explanation of why and how are in this entry. (Photo credit by motjetom) Eclipse workspaces To understand why I wished to write about this, one has to know that many developers -...

Just under a year ago, we introduced the Red Hat Enterprise Linux Developer Toolset 1.0 which provides the latest, stable open source developer tool versions at an accelerated cadence than that of Red Hat Enterprise Linux. That version started with gcc 4.7 and gdb 7.4. Since then, we've added V1.1 with some additional components and today we are announcing V2.0 beta that adds Eclipse, and more: Eclipse 4.3.0 weaves together a full set of tools required for software development in...
