Apache Camel integration testing – Part 1

Posted on November 21st, 2014 by Christoph

Apache Camel is a great mediation and routing framework that integrates with almost every enterprise messaging transport. In the past I have experienced Camel projects struggling with integration testing where the actual message interfaces to boundary applications are not tested properly in an automated way.

So in a series of posts I would like to talk about integration testing strategies for Apache Camel projects using the Citrus integration test framework.

  • Part 1: Setup the Citrus test project and interact with a sample Apache Camel project with JMS and SOAP WebService components
  • Part 2: Invoke Camel routes from Citrus test cases and validate outbound messages
  • Part 3: Test error situations with Camel exception handling

GoTo Conference Berlin 2014

Posted on November 20th, 2014 by Johannes Pieringer

The GoTo Conference Berlin is part of a conference series with stops in Berlin, Chicago, Amsterdam, Aarhus and Copenhagen. The 3 day conference was divided in workshops on the first day and talks on the second and third day.

The talks and the catering were very well organized. The only drawback was, that the WLAN wasn’t working most of the time.

Now lets go through the talks:

Devoxx 2014, Day 5 & Wrap-Up

Posted on November 18th, 2014 by Christoph

Devoxx is over, sadly, and under normal circumstances this would be the time when we Devoxxians return to our everyday’s lives for another year.

However, this time it is different: At Google’s booth at the exhibition area we got their latest Cardboard gadget. Cardboard is a virtual reality viewer for Android phones and it is absolutely the greatest thing I have ever seen on a phone. The Cardboard app comes with a lot of fancy demos like a virtual reality tour through Versailles, flying around in Google earth and even a short animated 360° movie.

For me Devoxx did not stop when I left the venue this afternoon. Devoxx continued at home when I opened that Cardboard give-away. Infinite possibilities, the motto of this year’s Devoxx, couldn’t fit better. I definitely need to check it out and learn more about it.

Thank you very much for that, Google! (fabian)

See you next year, at the Devoxx. But before that lets have a look at the last day and a very inspiring talk on Android Wear:

Devoxx 2014, Day 4

Posted on November 14th, 2014 by Christoph

First of all a small notice on the Ignite sessions at Devoxx. The 5 minute talks with 20 slides were very entertaining and I am glad that Roland kind of talked us into this. The sessions take place during lunch break but it is definitely worth taking the time and listening to the talks.

Now let’s go through the talks of day 4 in Antwerp.

Devoxx 2014, Ignite Sessions

Posted on November 13th, 2014 by Christoph

“Devoxx Ignite sessions” (fabian)

Devoxx ignite sessions are a great thing: Each speaker has 20 slides in 5 minutes, the slides are auto-forwarding, so each slide is up 15 seconds. During the hour long ignite session you would hear 8 talks. Today, we learned how to make money, ride a mountain bike, do performance tuning, save the planet, be a diabolical developer, share a house, do open source, decode the airspace, and why Stephen Chin’s job sucks.

The format reminds a bit of TED’s talks, talks are quick, innovative, and engaging. Sometimes I even felt that the take away of a five minute talk is not necessarily less than the take away of the three hour university sessions.

So the group of ConSol Devoxxians is now complete as the rest of the posse has finally arrived for the upcoming conference days in Antwerp. And we are all excited to hear the latest news in the opening keynote from Stephan Janssen, who is best named as the father of the Devoxx conference and the Parleys platform.

Stephan has some great announcements in his keynote. One of them is to welcome Devoxx Poland as new family member in Krakow next year, which is indeed great news for our ConSol colleagues in Poland.

EPEL-Repository in CentOS einbinden

Posted on October 11th, 2014 by lausser

Immer wenn ich bei einem CentOS-System Pakete aus der EPEL-Kollektion installieren will, muss ich in meinem schlauen Büchlein blättern oder rumgoogeln, wie das Einbinden des EPEL-Repositories funktioniert. Deshalb halte ich es mal an dieser Stelle hier fest, dann finde ich das richtige Kommando beim nächsten Mal auf Anhieb.
