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 product flags defined in the JVM and to be honest, I’ve only a vague idea of the effect may have on a runtime.
Introducing a project for developing a premises guardian system in Java with actors.
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...
Need to use a generic Range class but don't want to include rather huge all-inclusive libraries? Here is your solution: Simply add eu.headcrashing.treasure-chest:RangeClass as a dependency to your Maven POM descriptor!
Today I had enough from typing lenghty paths and ".jar" extensions, so I taught Windows to deal with JARs the same way it deals with EXEs and CMDs.
Combining JavaFX 2.x and the NetBeans Platform has proven complementary in making some very useful "At-a-Glance" displays associated with NASA Ground System daily data product generation. The combination has proved to be a very effective pattern to extend and this post along with some following posts will explore this. Explanation, Justification and some cool screenshots will be provided.

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-...
Every software project experiences the complexity of incorporating open-source and proprietary components that use a wide range of licenses. The BIG question is what can be done to avoid license violations in the face of countless dependencies.
This blog post will show you how you can extend your continuous integration builds to automatically track license usage in artifact dependencies and notify you about any license violations as they occur. This allows you to easily identify the problematic dependencies and deal with them early on, during the development process.
The Full Cycle - From Modules to Automated License Checks
Here is how it all works together to automatically extract and apply licensing information and conduct license violation checks on the fly:
Apache maven is supposed to solve the classpath hell; or so I´ve been told...
Started using maven 2 in a multi-pom project. One of the requirements is to be able to deploy EAR files to Weblogic.
After looking around it seemed like the most stable way of doing this with maven and Weblogic 10.x is to use the Weblogic Ant task. Not ideal since we are migrating away from Ant, but still okay.
Web Development Tools
So, what does it take move your existing application to the cloud? As you'd hope, not much.

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.
