Transforming JSON Structures with Java and JOLT

Sun, 29 Jan 2017 00:00:00 +0100

When it comes to web-services (especially RESTful web-services), configuration files or other data-descriptors, the JavaScript Object Notation, short: JSON is often used as format of choice.

As the task arises to transform these JSON structures, I have seen a variety of different approaches from converting JSON into XML using JAX-B, applying XSLT, transforming into JSON again on the one hand to loading JSON structures into Hash-maps of Hash-maps (..) and manually removing single elements from these collections on the other hand.

Creating a XMPP Chat Bot with Apache Camel

Sun, 12 Oct 2014 00:00:00 +0200

Apache Camel not only is one of my favourite frameworks ever but it also allows the humble developer to create a full blown chat bot within a few lines of code and using the Camel XMPP component.

In the following tutorial, we’re going to create a simple chat bot and since Atlassian’s HipChat basic plan is now free for unlimited users, we’re using HipChat as our play- and testing ground for the bot.

Using Apache Camel with Scala and the Camel Scala DSL

Wed, 13 Feb 2013 00:00:00 +0100

Whenever I encounter a situation where I have to mix a blend of different services and endpoints and apply one or more of the traditional enterprise integration patterns then Apache Camel often is my weapon of choice.

I simply love how easy it is to set up some datasources, add some routing magic, data transformers, load balancers, content enrichers and enjoy the result.

Another thing that I’m beginning to love is Scala and so this is the perfect time to write an article about using Scala and Apache Camel together.
