BPMN2 and jBPM5

1. BPMN2 and jBPM5 Kris Verlaenen jBPM5 Lead

2. Overview <ul><li>Rules and Processes

3. jBPM5

4. Guvnor

5. Flexible and adaptive processes </li></ul>

6. What is a business process? <ul><li>State

7. Sequence

8. Long-lived </li></ul><ul><li>Persistence

9. Generic

10. More stable </li></ul>A business process is a process that describes the order in which a series of steps need to be executed, using a flow chart.

11. Combining processes and rules <ul><li>Integration </li><ul><li>From loose coupling (decision services)

12. To advanced integration (process rules) </li></ul><li>Unification </li><ul><li>Rules and processes are different types of business knowledge assets

13. Tooling (IDE, repository, management) </li></ul></ul>

14. RuleFlow

15. <ul><li>RuleFlow : describing the order in which rule groups should be evaluated

16. Process Rules : Evaluate constraints

17. RuleSet : Evaluating a set of rules in your process (= local decision service)

18. Assignment rules

19. Describing exceptional situations using rules

20. Modularizing concerns using rules

21. Using rules to dynamically alter the behavior of the process </li></ul>Rules and Process Integration

22. Model Deploy Execute Monitor Analyze Life Cycle Mining Analysis Optimization Simulation Testing Design Monitoring Reporting Execution Integration Deployment Management Audit Human Interaction Collaboration

23. Vision jBPM as the process engine in a knowledge-oriented platform for developers and business users

24. Key Characteristics of jBPM5 <ul><li>Open-source business process management project offering: </li></ul><ul><ul><li>generic process engine supporting native BPMN 2.0 execution

25. targeting developers and business users

26. collaboration, management and monitoring using web-based consoles

27. powerful rules and event integration </li></ul></ul>

28. From Workflow to BPM <ul><li>Core engine is a workflow engine in pure Java </li></ul><ul><ul><li>state transitions

29. lightweight

30. embeddable

31. generic, extensible </li></ul></ul>Core Engine

32. Core Engine Knowledge Base Stateful Knowledge Session Process Definition Process Instance

33. BPMN 2.0 Example < definitions ... > < process id="com.sample.bpmn.hello" name="Hello World" > < startEvent id="_1" name="StartProcess" /> < sequenceFlow sourceRef="_1" targetRef="_2" /> < scriptTask id="_2" name="Hello" > < script >System.out.println("Hello World");</ script > </ scriptTask > < sequenceFlow sourceRef="_2" targetRef="_3" /> < endEvent id="_3" name="EndProcess" /> </ process > </ definitions > < definitions ... > < process id="com.sample.bpmn.hello" name="Hello World" > < startEvent id="_1" name="StartProcess" /> < sequenceFlow sourceRef="_1" targetRef="_2" /> < scriptTask id="_2" name="Hello" > < script >System.out.println("Hello World");</ script > </ scriptTask > < sequenceFlow sourceRef="_2" targetRef="_3" /> < endEvent id="_3" name="EndProcess" /> </ process > </ definitions >

34. Java Interface ProcessRuntime interface <ul><li>startProcess(processId)

35. startProcess(processId, parameters)

36. signalEvent(type, event)

37. signalEvent(type, event, instanceId)

38. abortProcessInstance(instanceId)

39. getProcessInstance(instanceId)

40. … </li></ul>

41. Java Example // (1) Create knowledge base and add process definition KnowledgeBuilder kbuilder = ... kbuilder.add( ..., "sample.bpmn", ResourceType.BPMN2); KnowledgeBase kbase = kbuilder.newKnowledgeBase(); // (2) Create new stateful knowledge session StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); // (3) Start a new process instance ksession.startProcess(“com.sample.bpmn.hello”);

42. Domain-specific Services <ul><li>Extend palette with domain-specific, declarative service nodes </li></ul><ul><ul><li>define input / output parameters

43. runtime binding </li></ul></ul>

44. Guvnor <ul><li>Guvnor as knowledge repository </li></ul><ul><ul><li>BPMN2 processes

45. Task and process forms

46. Model </li></ul></ul><ul><li>Web-based process editor (Oryx)

47. Build, deploy, test, manage and collaboration features </li></ul>

48. Other Features <ul><li>Persistence / transactions </li><ul><li>Command-based

49. JPA / JTA

50. Pluggable </li></ul><li>Human Task Service

51. Eclipse plugin

52. Web-based management console

53. Installer </li></ul>

54. Flexible and Adaptive Processes Traditional workflow systems have problems with change, complexity, flexibility, data-intensive applications, etc. <ul><li>Adaptive Case Management (ACM)

55. Unstructured, non-lineair or flexible processes

56. Event-driven BPM (edBPM) </li></ul>

57. Processes + Rules + Events

58. Flexible processes
