Tech Tip #25 showed how to configure WildFly on Raspberry Pi. This tech tip will show how to setup a WildFly managed domain over two hosts running on Raspberry Pi.
Lets understand some basic concepts first.
WildFly can run in two modes:
Managed Domain allows you to run and manage a multi-server domain topology
Standalone allows to run a single instance of server
Multiple standalone instances...

A JBoss User Group (JBUG) is a group of people who share a common interest in JBoss technologies. They are organized and supported by the community and meet on a regular basis to discuss new technologies, development methodologies, interesting use cases, and other technical topics. The common goal is to provide education, help, and social events for the community and to promote open source....

This is the third part (part 1, part 2) of a multi-part video series where Lincoln Baxter (@lincolnthree) and I are interactively building a Forge addon to add Java EE 7 Batch functionality.
Part 1 showed how to get started with creating an addon, add relevant POM dependencies, build and install the addon using Forge shell, add a new command batch-new-jobxml, and add --reader, --processor, --...

JBoss Forge is the fastest way to build your Java EE applications, and not even tied to a particular IDE or an Application Server. Tech Tip #17 explained how to build a simple Java EE application rapidly, and deploy it on WildFly. JBoss Developer Studio provide a very neat integration with Forge as well. The instructions from the video are also explained in a text-based script here.

Oracle User Group Norway - Spring Seminar
The OUGs are not the typical place for Java developers or community managers (namely me) to be. But OUGN has been working hard to build out a decent Java track with very good speakers, and it was a chance to see how the broader Oracle community is working together when it comes to Java. Also, I was in the neighborhood, more or less, and had never been on...

Inaugural JavaLand in Germany
It took trains, planes, and automobiles to get there. I had heard Germany ran some great conferences, but JavaLand was promised to be outstanding. Kevin already did an interview with one of the organizers, Markus Eisele, about why JavaLand is different. (https://weblogs.java.net/blog/editor/archive/2014/03/01/java-conferences...) But, I got to see first-hand if they...

On January 2nd I received a New Year's gift, my "Welcome to Oracle Cloud" email. I had requested a 30-day free trial back on October 17, when the Oracle Cloud was first announced, and had basically forgotten all about it. If you haven't already, request a trial account for yourself:
The Oracle Cloud integrates very nicely with Eclipse, NetBeans and JDeveloper, where you can develop and...

Recently, there is a heaty debate regarding TDD which started by DHH when he claimed that TDD is dead.
This ongoing debate managed to capture the attention of developers world, including us.
Some mini debates have happened in our office regarding the right practices to do testing.
In this article, I will represent my own view.
How many kinds of tests have you seen?
From the time I joined industry...

I've been developing webapps pretty much since the start of the web in the second half of the 90s, and in Java ever since the first edition of Java EE. During that time, I've met many people and have seen many different approaches to both the development and the testing of the code.
One of the funnier parts of web app testing was a testing method used by one of the people I worked with. Between...

Server-Sent Events (SSE) is part of HTML5. SSE is a simple, undirectional communication from server to browser. It allows server to push data to client once a connection is established. The entire point of SSE is to make it easy for the server to push messages to the browser, once the browser has first established a connection to the server. These messages are of the form "field: value" with...

Recently, we were tasked to develop a SAAS application for big data analysis. To do data mining, the system need to store multi billion public posts in the database and run the classification process on them.
Classification in our context is a slow, resource intensive and painful process to assign a topic or sentiment to any record in the database. The process can last up to 24 hours with our...

This a fun story rather than a deep technical discussion of some performance issue, measure or tool. My memory was jogged by a story (http://www.folklore.org/StoryView.py?story=Negative_2000_Lines_Of_Code.txt) in which Bill Atkinson reported producing -2000 lines of code on his weekly productivity report and by Kevlin Henney retweeting one of my one liners, features are the asset, code is a...

We've been using TDD for Mojarra for nearly a decade now and after all that time, we have decent number of tests. For historical reasons these tests mostly use GlassFish, but we are naturally migrating them to use WebLogic Server. As part of that work, I had to learn how to set up a simple cluster in WebLogic Server 12.1.2 to validate the fix for this bug that prevents @ViewScoped beans from...

Runtime type information (RTTI) refers to the correct identification of the type of your objects at run time. When you write code, it is generally desirable to do so in a way that takes advantage of OOP features like encapsulation and inheritance to make your program easily extensible, by for instance, as much as possible manipulating references to base classes and letting polymorphism work for...

While parts of the cloud IT that are still being hyped are changing rapidly, the whole segment is not past the hype yet. The cloud report  that Gartner published 9 months ago still holds true today.
Reports of disillusioned customers of such solutions  are a clear sign that the hype might have reached its peak for most parts of cloud offerings, though. And while many articles discuss the...
