3. BPM as a Discipline

Management discipline

They all seem very busy

Non technical

People to people

• What, not how

• Can be vague

• Unrelated to software architecture

Often include diagrams

4. BPM as Software Engineering

Aspect of software expressed as a graph

Specifies execution flow

BPMS runs process executions

Its software

• DSL

• Execute on one system

• Central dispatcher

• Multiple participants

• Wait states

5. Traditional BPM Vendors

Stack Integrators

• Oracle, IBM, SAP

• BPEL is integration technology

• Atomic operation is WSDL service invocations

• Service orchestration as solution for BPM ?

• • Lost of tooling required to hide clumsy basics

Pure plays

• Top down

• • Automagical

• BPM Suite has its own software architecture

• • Doesnt embed within users software architecture

• • Monolithic server

• • Hard to integrate

6. jBPM !

Bottom Up

• No magic

Server or embedded

• Not monolithic

• Just a library

Freedom

• Use the most appropriate tech

• • Java, groovy, web services, SQL

• Java excellent dispatcher technology

7. jBPMs Modelling Advantage

Typical user story

• Order entry

Business person goes

• Click on the button in the screen

• Clerk gets an email

• Escalate if it takes too long

Developer goes

• GWT gives me browser

• RESTfull webservice communication with server

• SEAM can invoke my ejb 3 beans

• EJB 3 beans have required transaction demarcation

• SEAM integrates with my business process layer

• Sending email must be done asynchronous

8. jBPMs Modelling Advantage

No forced link between graph and transaction

• Embeddable

• Flexible transaction demarcation

Hidden event listeners

9. jBPMs Modelling Advantage Your App Your Architecture jBPM Business Analyst Developer 10. jBPMs Modelling Advantage Your App Your Architecture jBPM Business Analyst Developer 11. jBPMs Embeddable Advantage

Structure your software

Software is a combination of

• Process

• Domain model

• UI

Process inside your architecture

• Binds to users transaction (JEE, JSE, SEAM, Spring,)

• Stores data in users database

• Links to domain model objects

• Test inside users test suite

12. jBPMs Embeddable Advantage

E.g. plain webapp

• Spring, hibernate

• Deployed on Tomcat

jBPM has Job executor

• Transactional timers

• Asynchronous continuations

Transaction 1 Transaction 2 13. jBPMs Embeddable Advantage

Works with plain Java code

High level asynchronous transactional modelling

• Standard Javathanks to jobexecutor

• Enterprise Javawithout deployment descriptor hell

• Seam

• Spring

14. jBPMs Use Cases

Orchestrating Human Tasks

Transactional Script

• EJB orchestration

• Service orchestration

Pageflow

15.

< process name = "TaskCandidateGroups" >

< start >

< transition to = "review" />

start >

< task name = "review"

candidate-users = "johndoe, joesmoe" >

< transition to = "wait" />

task >

< state name = "wait"/>

process >

16.

• • • deployJpdlResource(

• • • /process.jpdl.xml

• • • );

Execution execution = executionService

.startProcessInstanceByKey( "TaskCandidates" );

String executionId = execution.getId();

List taskList =

taskService.getGroupTaskList( "johndoe" , 0, 10);

assertEquals(1, taskList.size());

Task task = taskList.get(0);

assertEquals( "review" , task.getName());

taskList =

taskService.getGroupTaskList( "joesmoe" , 0, 10);

assertEquals(1, taskList.size());

task = taskList.get(0);

assertEquals( "review" , task.getName());

17. Multiple Process Languages 18. jBPM Key Business Values

Step away from

• Business analysts can work with our tool :-)

Real bridge

• Based on good communication

• Leaves tech things with developers

• Creates a common language

First generally applicable solution forBPM as a discipline

19. jBPM Key Technical Values

No hokus pokus

Take away the TX plumbing

Structure software

• Get overview beyond transactions

Learn 1 workflow/BPM technology

• Leverage that knowledge investment it in all your projects

• The one-stop-shop argument

Simple & lightweight
