# Introduction

Soffid Business Processes use JBoss JBPM engine. You can find the original JBPM documentation [here](https://docs.jboss.org/jbpm/v3/userguide/).

In order to develop a new business process addon you need Eclipse Java EE IDE for Web Developers and three plugins installed on it:

- JBPM plugin. You can find it on [http://fr.sourceforge.jp/projects/sfnet\_jbpm/downloads/jBPM%20Process%20Designer/jbpm-jpdl-designer-3.1.7/jbpm-jpdl-designer-site-3.1.7.zip/](http://fr.sourceforge.jp/projects/sfnet_jbpm/downloads/jBPM%20Process%20Designer/jbpm-jpdl-designer-3.1.7/jbpm-jpdl-designer-site-3.1.7.zip/) and you can install it from **Help/Install New Software/Add** and select the file you have downloaded with the **Archive** button.
- ZK Studio. Follow this instructions in order to install [http://books.zkoss.org/wiki/ZK\_Studio\_Essentials/Installation#Install\_ZK\_Studio](http://books.zkoss.org/wiki/ZK_Studio_Essentials/Installation#Install_ZK_Studio).
- maven plugin (m2e-Maven Integration for Eclipse). Go to Help/Install New Software/Work with: "All Available Sites" and select the pluguin.

The business process addon can be build using the com.soffid.tools:maven-par-plugin addon.

They follow the JBPM conventions for .par files:

- **/processdefinition.xml** contains the business process definition that you define.
- **/processimage.jpg** contains a bitmap representation of the definition you have created.
- **/gpd.xml** contains the position of business process elements on processimage.jpb bitmap.
- **/classes directory** contains the java compiled classes that support the business process that you implement.
- **/ui.xml** file describes some aspects not covered by processdefinition.xml, just like permissions, user interface and process versioning and upgrade.
- **/ui directory** contains the user interface (ZK) components that are needed to render the workflow tasks.

#### Examples
