footprint code coverage

With a weeks delay I held my short presentation at the Java User Group Hamburg about Artifactory yesterday. Even though the presentation was just about 15 minutes, the feedback was very positive and impression was that Artifactory is a full-featured alternative to Nexus.

The slides are available here: artifactory.pdf

I hope you find them useful.

Best regards, — Jan.

The next meeting of the Java User Group Hamburg will be covering Flex3, BlazeDS and Java. I myself will give a short introduction to Artifactory, a free maven repository software based on Wicket and JackRabbit.

The meeting takes place on May 20th, 2009 at 1900.

I hope to see you there!

Best regards, — Jan.

Scala get’s more and more attention. I’m trying to push the interest further and I’m happy to announce that my presentation at the Java Forum Stuttgart 2009 has been accepted.

There will also be a presentation of Scala in Hamburg at the Arbeitskreis Objekttechnologie Norddeutschland.

Both presentations will be held in german.

Please note the following dates for July in your calendar:

• 2009-07-02 – Java Forum Stuttgart 2009
• 2009-07-06 – Arbeitskreis Objekttechnologie Norddeutschland

I hope to see you!

Best regards, — Jan.

A couple of days ago I had a discussion on what would be the five libraries a developer should have had a good look at. This naturally is depending on what type of programming you’re focusing on, so you will seldom get the same list by two different developers.

Let’s define some base parameters: web application development with the JVM as targeted platform (choose your poison: Java, Scala, …). Here’s my list and some hints on why I think them more worth than one look:

Wicket

Nothings more thought-thru for developing web applications.

iBATIS

There’s a big hype about all those ORMs like Hibernate or EclipseLink. But when it comes to performance, flexibility and easyness, I think iBATIS the better approach. It’s very mature and with the upcoming next major release (a beta will be availabe in Q1 this year hopefully) it’ll gain some Java 5 toys to play with.

Quartz

When in need of scheduling tasks one shouldn’t have to bother on implementing anything else than the tasks. There are few libraries as mature and reliable as well as easy to develop with as this one.

Compass

Built on top of Lucene this library simplifys integrating search into you applications immensely!

TestNG

I think unit tests are overrated when you look at how they’re used in many cases – often it’s just for numbers and not quality testing. Every programmer should and needs to dive a bit deeper into this matter!

I left out other great libraries cause they don’t appear as often in my projects but are nonetheless very valuable. Among these are (for the records): Guice, FreeMarker, JFreeChart, iText, SpringSecurity, Joda Time, LOGBack.

And did I say that all of you should use Scala?!

Best regards, — Jan.

There has been an amazing many developers joining the presentations about Scala and Wicket at Google UK the day before yesterday. It was a great event and I enjoyed it very much as well.

Especially thanks to Cemal for his hospitality!

Here are he slides for all interested: Scala @ London Wicket

Hope to see yo again!
