For a project we are using Hippo to manage our content. We have a few components that interact with the repository using the connection pool as provided by hippo. I have modified the connection pool to increase the amount of logs and I have added statistics to the pool which can be exposed using JMX. Our custom components use this altered connection pool, but I the site did not. Our site makes use of the Hippo Site Toolkit, and I want to have this monitoring available as well.
In this blogpost I will explain the changes I made to the connection pool. After that I’ll show what to do to make this changed connection pool available to a site created with the HST and I’ll show a groovy script that reads the data from the remote servers using the JMX connection.
Apache ActiveMQ is an open source messaging framework. The ActiveMQ web site is not really clear on how to integrate it with the Spring framework. Therefore, I decided to write this post to explain how to use ActiveMQ in combination with Spring and clarify some points.
The good news is that you can run JMS inside a servlet container (e.g. Apache Tomcat) without the need for a JCA adapter. This means you do not need Jencks or something similar.
Today, I released version 0.6 of the Axon Framework. 0.6 has many new features and is another step towards full production readiness. There is still some work to do, but first, let’s take a look at what has changed…
For one of our project I needed to read zip files from a FTP server and import the content in a system. In this post I will explain how I have used the Spring Integration to connect with a FTP server and retrieve Zip files.

In one of our projects I had to parse and manipulate HTML. After searching for a nice HTML parser, I ended up using the open source library Jericho HTML Parser. Jericho provides you a lot of features including text extraction from HTML markup, rendering, formatting or compacting HTML. In this post I will show you a few of the features I have used.

In Taste, estimators are the bridge between the generic item- or user recommendation logic and the specific similarity algorithm. Estimators are mainly used as part of the recommendation process, however, they are also used for evaluating recommenders. Additionally, the ‘recommended because’ feature is also powered by an estimator. This blog covers some Taste internals and shows you how estimators are used within Taste via a few code samples.
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. I will explain how we used Spring 3 to create the feeds.
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 also includes some new features.
