Activiti

Introduction

The Activiti has a clear origin in the jBPM project of JBoss. The former lead developers of jBPM, Tom Baeyens and Joram Barrez, created a vibrant community around this process engine and they created a process virtual machine sub-project that enabled jBPM to be used for multiple process languages. At that point in time Alfresco was using jBPM in their document management system for the implementation of foremost workflow related functionality. But they were looking for a process engine with a more liberal open source license. ventually Alfresco decided to create a liberal Apache licensed open source process engine themselves and contacted Tom and Joram. Activiti was born! The Activiti project started off at a very fast pace and succeeded to do a monthly release of the tool stack until the stable 5.0 release in December 2010.
