Overview

• A high level introduction to Joget Workflow architecture:

– To whom each Joget Workflow component is targeted at?

– How we can achieve 2-way integration with external systems?

– Most importantly, how to do more and code less

Process Analyst:Using Workflow Designer• Workflow Designer is a web-based (Java Web Start)

process designer to design XPDL-compliant process diagram using intuitive interface.

• Examples of process components that can be drawn using Workflow Designer are:– Participant– Activity– Route (logical comparison)– Transition– Tool (integration to external system)

• Business process design can be deployed / updated into Workflow Engine from Workflow Designer.

Process Analyst:Using Workflow Management Console

• The participants and activities designed in Workflow Designer are notations to illustrate a process design. They must be further configured in Workflow Management Console, to map:– Human participant to user(s), user group(s),

organization chart entit(ies), or workflow variable.

– Activity to data form or system tool (plugin).

• A process package can be imported to / exported from Workflow Management Console to ease collaboration and deployment.

Administrator:Using Workflow Management Console

• Monitor running & completed processes

• Generate service level report

• Setup users, groups and organization chart

• Manage system setup, plugins, form variables and messages (internationalization)

End-User:Using Workflow Management Console

• Run process

• Perform tasks assigned

• View task history

End-User:Using Userview

• Userview is a customizable web application front-end that allows users to:

– Submit form data

– View submitted data

– View activities requiring his/her attention

– View aggregated report of all records submitted for an activity

– Search submitted data

• Active Directory / LDAP integration– LDAP Plugin

• SOAP / REST integration– JSON Plugin– SOAP Plugin– XML Plugin

• Custom programming– BeanShell Plugin (Java syntax)

Software Developer:Developing Plugins

• As Joget Workflow is aimed to be a generic workflow management system, specific requirements for integration to external system can be catered by developing a plugin:

– Write a Java class file that conforms to an interface

– Package the class file as OSGi JAR

– Upload the plugin package using Workflow Management Console

Software Developer:Using APIs

• Download Developer Reference from http://sourceforge.net/projects/jogetworkflow/files/

24

Software Developer:Build Domain Specific Solution

• Assuming you are developing a HR system

• Coded in any platform you prefer

• Using Joget Workflow to automate the workflow

• Easily integrate into Joget Workflow from HR application system using JSON and JavaScript

• And the processes (e.g. leave approval, claim approval, appraisal process) can be flexibly and easily modified anytime

25

Software Developer:Using Ajax JavaScript API

• Embed Task Inbox and Process List into external web application (such as portlet, SharePoint web part, intranet application)

• User authentication (login, logout) from external application

• Complete an assignment / activity from external application

26

Software Developer:Using HTTP JSON API• If you have an external application built, and would like

to use Joget Workflow to automate the workflow within this application, you can call the HTTP JSON APIs to integrate into Joget Workflow from external system.

• For example, upon submission of a Leave Application Form from Leave Module – an external application, developer can insert a HTTP JSON call to start a designated process in Joget Workflow.

• Output, if any, will be returned from the JSON API in JSON format.
