It has been an exciting year. Little over a year ago, I started developing a framework to make it easier for developers to implement a highly scalable en extensible architecture. The first public Axon release (0.3) came out in April 2010, and was far from feature complete. Now, almost a year later, Axon has proven […]
The Axon Framework 1.0 release is closing in. After over a year of development, all features planned for the 1.0 version are included. With the latest added features, Axon has become a powerful framework that helps developers implementing applications using on a CQRS based architecture. Although the 1.0-rc1 version doesn’t add a lot of new […]
Last saturday, february 5th, FOSDEM 2011 hosted the DataDevRoom where talks were given on topics surrounding data analysis with free and open source software. I was there and gave an introductory talk on clustering with Apache Mahout. In case you missed the conference, read on to learn about some of the talks or checkout the […]
In this post I explain how we implemented the way we created the RSS feeds in a project and the challenges that we had during the set-up. My colleague Jettro Coenradie explained in a previous post how you can create a feed using Rome and Spring 3, but didn’t elaborated on the Spring 3 part. […]
Today, I finalized the 0.5 release of the Axon Framework. There is quite a number of changes since the 0.4 version. The 0.5 version is a major step towards production readiness of the framework. Besides some changes to existing building blocks, such as the event bus, which is now much more powerful, the 0.5 version […]
The Enterprise Search market has long been dominated by commercial vendors and their products (e.g. Autonomy and Fast). We at JTeam feel that this era is finally over. At least for certain customers and requirements, there is finally a good Open Source alternative: Apache Solr, which is the Enterprise Search server based on Apache Lucene. […]
Good, solid language analysis is a very important asset for the quality of your search results. It is one of the features that for instance Microsoft Fast and Endeca are using as one of their unique selling points. However, you can get the same powerful analysis when using Apache Solr to implement your search.
Last week, I published the 0.4 release of the Axon Framework. Axon helps developers build high performance, scalable and extensible applications using the CQRS pattern. The 0.4 release is a major step towards 1.0, and includes transactional event handling, high-performance caching repositories and easy configuration of event sourcing support. Furthermore, we have also built a […]
Lately I have been looking into and playing around with the Google App Engine. In this post I want to give a little introduction to the Google App Engine, why it can be interesting and how to work with it.
In a number of blog entries we have spoken about the spatial search functionality that we have been developing here at Jteam. In the last two weeks, I have had a chance to contribute much of this work back to the Apache Lucene project with the goal of furthering the development of Lucene’s open source […]
