Writing this book was a life-changer for me. After I wrote Open Source ESBs in Action for Manning a few years ago, I focused on my daily job for some time, working with open source enterprise integration frameworks like Mule, Camel, ServiceMix, and Spring Integration. My work, over time, drove me to designing and developing processes and BPM , and I started using j BPM and WebSphere Process Server. Then I learned that the founder of the j BPM project, Tom Baeyens, was leaving JB oss to work on a new open source project, which was in stealth mode at that time (early 2010). When the first alpha version of Activiti was released, I told myself I had to contribute to that project, one way or another. A piece that was missing in the first stages of the Activiti project was an Eclipse plug-in. I had some email conversations with Tom about contributing the plug-in to Activiti. We met and he told me that his goal was to disrupt the process engine space with the Activiti project. My enthusiasm grew even more and I offered my time to start working on a first version of the Activiti Designer. Together with my former col- leagues, Tiese Barrell, Yvo Swillens, and Ron van Liempd, we were able to deliver a first version within a couple of months. As we became part of the Activiti developer community, my hands were itching to start writing a book about Activiti. I felt that a great open source process engine would need a detailed book to describe all the possibilities and potential it offers. Manning was eager to publish a book about Activiti, and, together with Ron, we started writing in the autumn of 2010. We had a hard time keeping up with the frequent releases and the new functionality that kept on coming. But, it also was a lot of fun to be able to write about a new functionality that was just (or about to be) released. After a few meet-ups with the Activiti developer community and a couple of nice dinners with the Activiti team, we began discussing the possibility of my joining Alfresco to work on Activiti. In May 2011, I accepted the offer and was able to begin working on Activiti full-time. In the meantime, the writing of this book fell a little behind schedule. There was so much interesting work to be done developing the Activiti Designer, working on the Activiti Engine, and starting in a new job, that time caught up with me. After I had settled in a bit, I took up the writing task again and began working on the remaining chapters. So here I am, at the end of the process. I’ve switched from being a consultant to an open source software engineer, and I’m close to completing my second book. And, just like with my previous book, I have a new family addition coinciding with the book’s release. I hope you will enjoy reading this book as much as I loved writing it!
