Keep the bar green to keep the code clean

The first time I stumbled over a JUnit @Rule annotation I was a bit irritated of the concept. Having a public field in a test case seemed somewhat odd and so I was reluctant to use it regularly. But after a while I got used to that and it turned...

Lately I had a chance to use the OSGi-JAX-RS-Connector library written by my dear fellow Holger Staudacher. The connector enables you to publish resources easily by registering @Path annotated types as OSGi services – which actually works quite nicely. While it is natural for me to write the service classes...

I really like the new RAP default theme introduced with the  RAP 1.5 Release (see New and Noteworthy). It looks much more sophisticated and refined thus making RAP applications look ‘desgned for the web’, rather than ‘ported to the web’ as before. However, while working on my last customer project,...

Just recently I had to implement equals() and hashCode() for several classes. With the aid of your favourite IDE, generating these methods is a matter of seconds. Well, if there weren’t the missing tests. As I tend to be obsessive when it comes to tests, I also want to have...

Long story short, I just discovered that Ctrl+Shift+M (Source > Add Import) can not only be used to add missing imports. It can also help with static imports. Executed on a reference to a qualified member (read Class.member), the refactoring will add a static import for the defining class and...

A little while ago I started a side project to support working with (zip) archive files in the Eclipse IDE. Initially it was more meant to revive my plug-in development knowledge and play around with some technologies like Tycho or SWTBot. But in the end, I though it might be...

My last post described how to accomplish stress- or load-testing of asynchronous REST/HTTP services with JMeter. However, running such tests often reveals that the system under test does not deal well with increasing load. The question is now how to find the bottleneck? Having an in-depth look at the code...

I recently gave a training course on – you guess it – RAP/RWT. And as it seems natural for a training targeted at developers it was very code centric and had many hands-on exercises. For hands-on exercises I find it useful to give a starting point so that tedious steps...

Although I have been using JMeter for stress- and load-testing of web applications a good few times it took us a while to figure out how to test asynchronous HTTP/REST based services with the tool. With us I mean a fellow programmer – Holger Staudacher, I have the honor to...
