In this blog item I want to show you the steps I took, the resources I found useful and some improvements to the article that seems a bit outdated. It is not an explanation of what Node.js is, but it does provide some help to get started on your own.

Over three years a go I wrote a blog post explaining the steps to upgrade you maven installation on Mac OS X Leopard. I have been using snow leopard now for a while and things changed a bit. In one of the comments to that post Oskar Carlstedt mentioned the steps required on Snow Leopard. This is all fine if you upgrade a minor version, but with maven 3 things changed a lot. I have some projects that require maven 2, we did not have time yet to fix problems we have with maven 3. Still I prefer using maven 3. Therefore I have to change between versions often. I decided to create a bash script to help me out.
Within this blogpost I’ll explain the installation of maven on Snow Leopard and I’ll present the bash script that can help you to switch between installations of maven.

Axon framework is rapidly moving to the 1.0 release. Just a few days a go Allard released the first release candidate. You can find more information in his blog item: First release candidate available. In the past I have created multiple samples that some aspect of axon or the integration of axon with other technologies.
In this blog post I want to go over all the axon samples that I have created, some of them together with Allard. I will explain the intentions of all the samples and the technologies used.
If you are missing samples, have good ideas, please let me know and I’ll see what I can do.

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 features to the previous release (0.7), it does represent a major milestone in Axon’s lifecycle. If Axon continues to prove it works as expected in production environments, the final 1.0 release can be expected before summer. Meanwhile, development will start on the remote messaging components required for scalability in larger systems.

Some time ago the NOS started providing their data as open data through an API. Using this API you can get the latest news items. You can limit the results to sport news. There is also a search available and a few more categories to find news for. The API is a REST like api and can return xml as well as JSON. In this blog post I am creating an API with the Spring framework RESTTemplate.

Today, I released the 0.7 version of Axon Framework. A lot has happened since 0.6, and that’s why it took a little longer for this version to come out. This new version is a huge step towards the 1.0, of which the first milestone release should be available before March 2011. All basic building blocks that you need to run a CQRS application have been implemented.
0.7 offers a large number of new features, such as support for Sagas, Event versioning, Spring Namespace Configuration, and many others, which I will describe in more detail.

At the end of 2010 I reviewed the book “OSGi and Apache Felix 3.0 Beginner’s Guide“. The people from packt publishing contacted me based on my involvement in the past with OSGi and felix. I wrote a number of blog posts on OSGi and felix and gave a presentation at the NLJug together with Allard about the topic. During the process of reviewing, I got enthusiastic about the book. I think the result is a good book for people that want to learn about OSGi by getting their hands dirty.
