==Download⌘==
* http://activiti.org/download.html
==Required software⌘==
* JDK 6+

* Eclipse (for Activiti Designer)
* Tomcat (any web container, but Tomcat is recommended)
* H2 database
===Required software - database⌘===
* Activiti Explorer runs an in-memory H2 database '''by default'''.
* To run the Activiti Explorer with a standalone H2 or another database the '''db.properties''' in the WEB-INF/classes of the Activiti Explorer web application should be changed.
* Change the line:
jdbc.url=jdbc:h2:mem:activiti
* to
jdbc.url=jdbc:h2:tcp://localhost/~/activiti
===H2 console⌘===
* open H2 console and connect

http://activiti.org/components.html

===Activiti Components - Modeling⌘===
* '''Activiti Modeler''' - a BPMN web modeler, part of the Activiti Explorer web application. Used to be based on Signavio.
* '''Activiti Designer''' - an Eclipse plugin which allows you to model BPMN 2.0 processes from within your IDE-environment.
* '''Activiti Kickstart''' - tool that allows creating processes with no XML or programming language knowledge

===Activiti Components - Runtime⌘===
* '''Activiti Engine''' - Java process engine that runs BPMN 2 processes
[[File:ClipCapIt-150731-123308.PNG]]

<small>source: http://activiti.org/userguide/index.html</small>
* The engine API is the most common way of interacting with Activiti. The central starting point is the ProcessEngine

===Activiti Components - Management⌘===
[[File:ClipCapIt-150721-105546.PNG]]
* '''Activiti Explorer''' - a web application that provides access to the Activiti Engine runtime for all users of the system
** It includes task management, process instance inspection, management features and viewing reports based on statistical history data.
* '''Activiti REST''' - a REST API to the Activiti Engine
==Activiti Competitors⌘==
* [[File:ClipCapIt-150720-153732.PNG]]
** In 2010 the two key developers for jBPM: Tom Baeyens and Joram Barrez left Red Hat and started Activiti
** Activiti and jBPM have a lot of the same concepts
** jBPM is integrated with Drools
* [[File:ClipCapIt-150720-153910.PNG]]
** Activiti is more developer-focused
==Running Activiti⌘==
* start Tomcat
* open browser and go to http://localhost:8080/activiti-explorer
* login with kermit/kermit

=Activiti Modeler⌘=
[[File:ClipCapIt-150722-130944.PNG]]
* Activiti Modeler is a BPMN web modeler component that’s available as part of the Activiti Explorer web application.
* The Modeler is a fork of the Signavio Core Components project.
* Since version 5.17.0 maintained and developed as part of the Activiti project.
==Creating New Model⌘==
[[File:ClipCapIt-150722-132858.PNG]]
===Table-driven definition⌘===
[[File:ClipCapIt-150722-133303.PNG]]
* formerly known as "Kickstart"
* allows to build simple processes with a table-based view and adding forms
===Exercises⌘===
* DEMO: Creating new model using table-driven definition
* Exercise

==Task Management⌘==
[[File:ClipCapIt-150723-101836.PNG]]
==Processes⌘==
[[File:ClipCapIt-150723-103559.PNG]]
