When to use Apache Camel?

Posted in Application Server, EAI, ESB, Java / JEE, SOA on June 2nd, 2011 by Kai Wähner

Apache Camel is one of my favorite open source frameworks in the JVM / Java environment. It enables easy integration of different applications which use several protocols and technologies. This article shows when to use Apache Camel and when to use other alternatives.

The Problem: Enterprise Application Integration (EAI)

Enterprise application integration is necessary in almost every company due to new products and applications. Integrating these applications creates several problems. New paradigms come up every decade, for example client / server communication, Service-oriented Architecture (SOA) or Cloud Computing.

Evaluation of the Product SOAtest (Parasoft) to test your SOA

Posted in Java / JEE, SOA on March 12th, 2011 by Kai Wähner

In the last few days, I had to evaluate the product SOAtest (Parasoft). SOAtest is an Eclipse-based testing tool, which supports most important technologies and vendors to test your Service-oriented Architecture (SOA) technically.

What is SOAtest?

SOAtest is a tool to realize integration tests for your Service-orientied Architecture. It is Eclipse-based, therefore a developer can easily start with the product. You create most tests using the Eclipse-GUI, configure your specific tests (e.g. queue managers or database connections) and define the behaviour of the tests. The tests can also be integrated in your build server or test tools such as HP Quality Center.

First-hand Report about the Certification „SOA Certified Professional“ (SOACP) of soaschool.com

Posted in Cloud, IT Certifications, SOA on February 1st, 2011 by Kai Wähner

This article is a first-hand report about preparing for the SOACP certification and passing the exam. I decided to do this certification after I met Thomas Erl at the SOA Symposium 2010 in Berlin, Germany (see this older blog). I will tell you, why I like this certification and why (in my opinion) it makes a lot of sense. But I will also criticize some small details.

Bad Idea: A Keynote at SOA / Cloud Symposium 2010 in Berlin as Skype Call

Posted in Cloud, IT Conferences, SOA on October 6th, 2010 by Kai Wähner

Bad Idea: A Keynote at SOA / Cloud Symposium 2010 in Berlin as Skype Call ?!

In October 2010, I was at the IT conference „SOA / Cloud Symposium 2010“. I really liked the conference as I stated in another blog entry (http://www.kai-waehner.de/blog/2010/10/06/soa-cloud-symposium-2010-in-berlin/). But one concern really upset me…

What is a good keynote?

I really enjoyed the very good keynote of Christian Klezl (Vice President and Cloud Leader  of IBM Northeast Europe). This keynote contained everything I expect from a keynote: Good slides, good body language, interesting information, and a structured presentation which never becomes boring. Good job!

Report: SOA / Cloud Symposium 2010 in Berlin

Posted in Cloud, IT Conferences, SOA on October 6th, 2010 by Kai Wähner

SOA / Cloud Symposium 2010 in Berlin

I was at the SOA / Cloud Symposium (5th and 6th October 2010) in Berlin, Germany. As the name already states: The two main topics were SOA and Cloud. This IT conference is the most important vendor-independant confernce regarding these topics. Business drivers for SOA, concepts, design patterns, use case studies and best pracitices were presented by well known, world wide SOA experts.

The Sessions…

SOA experts such as Thomas Erl, Anne Thomas Mannes or Nicolai Josuttis hold some keynotes and further sessions. About 300 people participated. It was not easy to choose sessions, because nine parallel tracks were available. Thus, the thin conference booklet was not really thin :-) About 130 sessions (including keynotes and panels) were available.

Posted in Cloud, IT Certifications, Java / JEE, SOA on October 5th, 2010 by Kai Wähner

SOA / Cloud Certification of „soaschool.com“ (SOACP) by Thomas Erl or Sun / Oracle Java Enterprise (JEE) Certification?

Which one should I do?

What IT certification should I do next? This is what I wondered within the last weeks, after I passed the SCJP 6 successfully some months ago. I surfed the internet a lot to find information about possible IT certifications.

Posted in ESB, IT Conferences, Java / JEE, SOA on May 26th, 2010 by Kai Wähner

“FUSE Community Day 2010“ in Frankfurt

On May 25th 2010, I attended the „FUSE Community Day 2010“ in Frankfurt, Germany. That is a free one day conference, where some important open source projects of Apache are presented by Fuse – a company which offers commercial support for versions based on these products.

Which products were presented?

FUSE presented especially the following three products:

-       Camel: A lightweight framework which implements the common Enterprise Integration Patterns (EIP).

-       Active MQ: A message queuing software.

-       Service Mix. An Enterprise Service Bus (ESB), which uses for instance Camel and Active MQ.
