Web Development Tools
Bunyan is a NodeJS library that rethinks logging in some really useful ways. I wrote a Java port you can use in your applications.
In particular, with Bunyan, logs are JSON - and Bunyan comes with a great filtering and analysis tool.
The Java port uses some innovative techniques to make logging simple and foolproof - in particular, a use of AutoCloseable to make a logging code simple and...

As a test, I re-created the HRSystem application as described in the tutorial Developing Rich Web Applications With Oracle ADF. It's more than your basic Hello World application. For starters, the HR system application accesses a database. It also takes advantage of some sophisticated ADF features, such as graphs, page flows, auto-suggest, menu options to export to Excel and display in...

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...

This article is an extract from the upcoming book Jenkins: The Definitive Guide, to be published in the coming months with O'Reilly..
One of the more interesting plugins to emerge over the last few months is the Build Pipeline plugin, written by the folks at Centrum Systems. The Build Pipelines plugin takes the idea of build promotion further, and helps you design and monitor deployment...

By now, you are hopefully well aware that Glassfish 3.1 has been released. Because the performance group has been a little quiet lately, maybe you're thinking there aren't a lot of interesting performance features in this release. In fact, there are two key performance benefits: one which benefits developers, and one which is important for anyone using Glassfish's new clustering and high-...

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...

Just recently I was engaged to assist with an application that wasn’t behaving. The application, running in a 1.7.0_45 JVM, relied heavily on a 3rd party SAAS framework. That vendor provided my client with a list of 26 different JVM flags that should be set. When faced with this long list of flags I couldn’t resist asking why all the flags and why these flags. After all there are more than 700...

This post introduces a new Java actor based open source sub-project of the project "Learning Actors in Java". This work will develop a premises guardian system. A premises guardian system is a distributed application whose purpose is to support the physical protection of premises such as office buildings, campuses, apartment complexes, shopping malls, etc. Protecting information...

In this post we will be looking at code for a system designed to integrate all of the devices used to provide surveillance and security to extensive physical premises such as malls, campuses, and industrial parks. The approach I am taking involves the actor paradigm and the Java programming language. The selection of actors for this type of application is based on a number of...

I hate adding lots of huge multi-JAR all-purpose common libraries to rather small projects! Huge footprint just for a single class is a side effect of many popular frameworks, unfortunately, due to rather coarse-grained modularity. So I started to publish some of my commons (LPGL'ed) code as single-class self-contained artifacts on The Maven Central Repository.
You simple need a Range<T>...

After more than a decade in the Java universe, today I had just enough of remembering where my executable JARs are located and typing all the lengthy path names, so I finally taught Windows to deal with Java archives just the same way as it deals with it's native executables EXE and CMD. The trick is so simple that I actually do not understand why the JRE installer isn't applying it automatically...

As I get closer to deploying our 4th Operational Release of the Duke's Choice award winning GEONS Ground System Software I'm combining the NetBeans Platform with custom JavaFX views. This pattern provides some very useful "At-a-Glance" displays associated with daily data product generation. I'm fortunate to have access to quite a bit of complex and timely data much of which is custom to the...

Swing is not dead, still. While a whole lot of evangelists try to talk it dead, it is still part of the JRE. While SWT is not, still. And while JavaFX is not, still. Dispite all hypes and rumors. It is not even declared to be deprecated or obsolete. So in fact, there is no other real alternative to Swing as long as the GUI must work solely with JRE means (I won't say AWT is an alternative). And...

It eventually happened that I had to ensure that a class of mine is annotated in a particular way (I didn't want to bind the whole framework that uses the annotation just to ensure this single issue, as this was a unit test but not an integration test). So I wrote my own Hamcrest matcher with few pieces of reflection inside. Short time later I noticed that Hamcrest co-owner Nat PRYCE already did...

After a long 5 year wait, finally comes the new version of Java, jdk 7. The entire Java 7 project was divided into two sub-projects:
The coin project; which featured a few improvements to the language like switch with strings, mutil try etc.
Lamba's project containing some of the most innovative and complex features results in leaving the...

Devops and RPM Distribution
Regularly deploying and provisioning RPMs is increasingly becoming a common need. With devops automating every aspect of deployment, including setting up new hosts in virtualized environments, packaging systems such as RPM are getting more and more important. Managed RPMs provide a great level of control over installations and easy upgradability.
