Apache Camel and Scala: A Powerful Combination

Posted in EAI, Java / JEE on June 23rd, 2011 by Kai Wähner

I really like the integration framework Apache Camel and I also like Scala a lot. This article shows the basics of this combination. It is NO introduction to Apache Camel or Scala. I created a Git project to use it as simple startup for Camel-Scala-Maven projects using just the basic Camel concepts and only a few complex Scala features (i.e. very „Java-friendly“).

Problems when Starting with this Combination

I had several problems finding good resources for starting when I first tried to combine them. I have a lot of Camel experience, but only basic Scala knowledge. I tried to start with some projects which where already available in the web (e.g. from the „Camel in Action“ book or other Git examples).

Java / JVM – When to use Multicast (e.g. Tibco Rendevous) instead of Point-to-Point Messaging (JMS Implementations)

Posted in EAI, Java / JEE, SOA on May 18th, 2011 by Kai Wähner

Several solutions are available in the Java / JVM environment for messaging. All have in common that they exist for many years and still do its job in mission critical systems: Sending remote messages fast and reliable. There exist two different concepts which compete against each other for enterprise messaging solutions.  This article describes and compares Point-to-Point (diverse JMS implementations) and Multicast (e.g. Tibco Rendevous) messaging  to answer the question when to use which one. Although both solutions are available for many years now, this question is still very important – also for new software!

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.

Report: One-Day Conference “DOAG SIG Java 2010” about Java Enterprise Edition 6 (JEE 6)

Posted in Application Server, ESB, IT Conferences, Java / JEE on September 9th, 2010 by Kai Wähner

Today, I visited the one-day conference “DOAG SIG Java”. The main subject was the Java Enterprise Edition 6 (JEE 6).

I presented about applicability and limits of Java Server Faces 2.0 (JSF 2.0). You can download my (german) presentation slides:  DOAG SIG Java (Sept2010) – Einsatz und und Grenzen von Java Server Faces 2.0

“DOAG SIG Java” – What’s that?

The DOAG is a very large, german, independent Oracle-Usergroup. After the acqisition of Sun, the SIG Java was established to demarcate the Java technology from other business units (database, administration, …). Conferences are organized several times a year, the number of participants varies from 50 to 2000.

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.
