Due to issue SM-2287, Activiti needs to be added in ServiceMix 5 to the boot features before usage.
To add a boot feature, append the feature name to the
featuresBoot list in the
etc/org.apache.karaf.features.cfg. Afterwards, remove the data directory and start ServiceMix again.
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.
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
Hidden event listeners for decoupling software technical details from business level diagram
Ability to test process executions in isolation in a plain unit test
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
The Apache ServiceMix distributions also contain a Activiti example. You can find these example in the examples/activiti directory.
