Joget Workflow Integration Architecture Joget Workflow Integration Architecture Presentation Transcript

  • Workflow Integration Architecture www.joget.org
  • 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 2
  • 3
  • Do More with Joget Workflow THE CODELESS WAY 4
  • Process Analyst: Using Workflow Designer 5
  • 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. 6
  • Process Analyst: Using Workflow Management Console 7
  • 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. 8
  • Administrator: Using Workflow Management Console 9
  • 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) 10
  • End-User: Using Workflow Management Console 11
  • End-User: Using Workflow Management Console • Run process • Perform tasks assigned • View task history 12
  • End-User: Using Userview 13
  • 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 14
  • Do More with Joget Workflow JUST BY SETTING CONFIGURATIONS 15
  • Plugin Oriented Architecture • Enhance and extend Joget Workflow functionalities • Integrate to external systems • Reuse 1 plugin in multiple business processes • Free to use any plugin contributed into the open source world • Free to develop new plugins 16
  • Integrator: Using Plugins 17
  • Integrator: Using Plugins MySQL Plugin Email Plugin SOAP Plugin 18
  • Integrator: Configuring Plugin (Email Plugin) 19
  • Integrator: Configuring Plugin (MySQL Plugin) 20
  • Integrator: Plugins for System Integration • Database integration – Database Plugin – MySQL Plugin – Enterprise MySQL Plugin • Active Directory / LDAP integration – LDAP Plugin • SOAP / REST integration – JSON Plugin – SOAP Plugin – XML Plugin • Custom programming – BeanShell Plugin (Java syntax) 21
  • 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 22
  • Do More with Joget Workflow BY CODING LESS 23
  • Software Developer: Using APIs • Download Developer Reference from http://sourceforge.net/projects/jogetworkflo w/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. 27
  • Examples of API Use Case 1. Display Joget Workflow task inbox in other web applications, such as portal (SharePoint, Liferay) and content management system (Joomla!, WordPress, Alfresco). 28
  • Examples of API Use Case 2. Start a process in Joget Workflow, from external system. 2. Start evaluation and approval PHP process in Joget Workflow JSON API 1. Data saved into external database MySQL 29
  • Examples of API Use Case 3. Complete a workflow activity from external system, and pass a workflow variable value. A .NET library Complete a workflow activity in Joget Workflow, and inform Joget Workflow of the status, by setting a workflow variable value JavaScript API 30
  • Examples of API Use Case 4. Single-sign-on from external application. Web Application SSO into Joget Workflow from external web application, even when both applications are using different user base JavaScript API 31
  • Map Activity to External URL 32
  • Infinite Possibilities Various process-driven Grant Hospital E- solutions DMS HR Suite ERP CMS Approval Mngt Payment Varying platforms, integrate using JSON & Java EE .NET PHP JavaScript API Workflow Engine for Process Automation Persistence layer built on Hibernate, to achieve database compatibility with a number of DBMS MySQL SQL Server Oracle 33
  • with Joget Workflow, you too can DO MORE, CODE LESS 34
