h2. Introducing Activiti

Activiti is a BPMN 2.0 process-engine framework that implements the BPMN 2.0 specification. 
It's able to  perform BPMN 2.0 functions including deploy process definitions, start new process instances, execute user tasks ecc.ecc..
Its core is a super-fast and rock-solid BPMN 2 process engine for Java.


h3. Activiti Engine
This is the heart of the Activiti project.  It's a Java process engine that runs BPMN 2 processes natively.  It will have the following key properties:


* Allows user updates to be combined with process updates in a single transaction
* Runs on any Java environment like Spring, JTA, standalone with any form of transaction demarcation
* Easy to get up and running with the setup utility
* Built to support the cloud scalability from the ground up
* Very simple to add new custom activity types and complete dedicated process languages
* Transactional timers
* Asynchronous continuations
* Hidden event listeners for decoupling software technical details from business level diagram
* Ability to test process executions in isolation in a plain unit test


h2. Goal of this guide

The goal of this guide is to look into the details for using Activiti inside ServiceMix:

* create a project
* write and debug a simple process

h2. Examples

The Apache ServiceMix distributions also contain a Activiti example.  You can find these example in the {{examples/activiti}} directory.
