5. jBPM5 Developer Guide
Chapter 1 - Theoretical Background
● What is a Business Process?
● What is BPM?
○ Stages

6. Business Process
● Describes Systems and Humans Interactions
● Formalize how the work is being done
● Allows us to recognize potential problems
● and they look like...

7. Business Process

8. Business Process Management

9. jBPM5 Developer Guide
Chapter 2 - BPM Systems (Structure)
● Allows us to execute and automate our Business
Processes
● Business Processes will guide the company activities
● There are so many advantages...

10. jBPM5 Developer Guide
Chapter 2 - BPM Systems (Structure)
● Advantages
○ Performance Metrics
○ Recognize and deal with business exceptions
○ Business Agility
○ Improve your decision making data streams
○ Get an instant snapshot about the company work
load
○ Quickly adapt your business processes to reflect
changes in your business

11. BPM System Structure

12. jBPM5 Developer Guide
Chapter 3 - BPMN 2.0
● Standard Specification
(de-facto standard)
● Defines the Notation
● Defines the Execution Semantic
● Allows interoperability between BPMS'

13. jBPM5 Developer Guide
Chapter 4 - Knowing Your Toolbox
● Infrastructure:
○ Guvnor
● Design:
○ Eclipse Plugin (deprecated)
○ Web Process Editor ("official")
○ Eclipse BPMN2.0 Editor
● Runtime:
○ jBPM5 GWT Process Server
○ jBPM5 GWT Console

14. jBPM5 Developer Guide
Chapter 5 - Modeling Tools
● Web Process Designer:
○ Integrated with Guvnor BRMS
○ Standard BPMN2.0 + jBPM5 extensions
○ Process Definition Validation
○ Domain Specific Tasks
○ Integration with Service Repository

15. jBPM5 Developer Guide
Chapter 6 - Domain Specific Processes
● Attach Domain Specific Constructs to your BPs
● Create connectors to interact with your existing
(legacy) systems
● Clear separation between definition and
implementation.
● Different implementations for different environments

16. jBPM5 Developer Guide
Chapter 7 - Human Interactions
● Optimize your working force
● Gather right the information for the right people
● Optimize how the tasks are being performed
● Obtain a realistic metric about how the work is being
done inside your organization

17. Tasks List

18. Task Form

19. Task Form

20. jBPM5 Developer Guide
Chapter 8 - Persistence & Transactions
● Dealing with Long Running Processes and
System Integrations requires a deep
understand about these topics
● Drools and jBPM share the same
mechanisms for Persistence and
Transactions

21. Drools & jBPM

22. Persistence
● Based on JPA
● Every time that a process reach a safe point it is
persisted until an external interaction is completed
● All the data associated with the process is stored as
well

23. Transactions
● Based on JTA
● Most of the time business processes are about
System Integrations
○ If our processes are interacting with
transactional resources a 2 phase commit
strategy can be used to guarantee
coherence inside the same transaction

24. jBPM Evolution
Chapter 9 - Smart Processes using Rules
● The Drools Rule Engine
● How our processes can benefit from the power
of a Rule Engine?
● What kind of things we will be able to do?
● What's the difference between jBPM5 and
jBPM3/jBPM4 and other BPMS?
● Simplify our business processes to express more
accurately how the business works

25. jBPM Evolution
Chapter 10 - Reactive Processes using Drools Fusion
● Temporal Reasoning
● We will be able to co-relate and identify time
sensitive situations
● A whole new world of possibilities

26. jBPM Evolution
Chapter 11 - Architectural & Integration Tips
● The integration with the Rule Engine give us a
richer context to work on
● The stateful nature of this context will allows us
to build smarter applications that keeps track of
multiple business process execution
● Different architectures can be built using these
concepts

27. Future - Drools/jBPM 6
● Tooling
○ UberFire (GWT+ERRAI) Workbench
■ http://droolsjbpm.github.com/uberfire/
○ jBPM Console NG
○ Guvnor NG
● CDI (JSR-299) integration

28. Release Process + Rules

29. Demo

30. Demo - Rules
Monitor with
Rules

31. Demo - Rules
We cannot have
two Release
Processes Using
the same Release
Path and release
files at the same
time

32. Demo - Rules
Create Ad-Hoc Task
if Trigger Test takes
too much time
