jBPM5 - Bringing more power to your business processes

2. Kris Verlaenen – jBPM Lead May 5 th , 2011 jBPM5 : Bringing more Power to your Business Processes

3. What is BPM? A business process is a process that describes the order in which a series of steps need to be executed, using a flow chart. Business Process Management

4. Why BPM? <ul><li>Visibility

5. Monitoring

6. Higher-level </li></ul><ul><li>Continuous improvement

7. Speed of development

8. Increased agility </li></ul>

9. 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

10. targeting developers and business users

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

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

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

14. lightweight

15. embeddable

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

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

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

19. startProcess(processId, parameters)

20. signalEvent(type, event)

21. signalEvent(type, event, instanceId)

22. abortProcessInstance(instanceId)

23. getProcessInstance(instanceId)

24. … </li></ul>

25. 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”);

26. From Workflow to BPM Core Engine

27. From Workflow to BPM Core Engine BPMN 2.0 XML

28. BPMN 2.0 <ul><li>OMG specification </li><ul><li>Model

29. Notation

30. Execution semantics </li></ul><li>Understandable by all business users

31. Process, collaboration, choreography

32. Extensible </li></ul>

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. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions JPA JTA

35. Persistence and Transactions <ul><li>Persistence (JPA, pluggable) </li><ul><li>Runtime persistence

36. History logging

37. Services </li></ul><li>Transactions (JTA, pluggable) </li><ul><li>Command-scoped

38. User-defined </li></ul></ul>

39. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions Events History Log Management Console BAM

40. Console <ul><li>Web-based management

41. Business user

42. Features </li></ul><ul><ul><li>Process instance management

43. User task lists / forms

44. Reporting </li></ul></ul>

45. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions Events Integration Domain-specific Processes Human Task Service ESB

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

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

48. Human task service <ul><li>User task

49. Human task service (WS-HT) </li></ul><ul><ul><li>Task lists

50. Task life cycle </li></ul></ul><ul><li>Task clients </li></ul><ul><ul><li>Task forms </li></ul></ul>

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

52. Processes + Rules + Events

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

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

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

56. Knowledge Repository <ul><li>Guvnor as knowledge repository </li></ul><ul><ul><li>Processes

57. Rules

58. Task and process forms

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

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

61. Architecture <ul><li>From “embedded” to “as a service”

62. Command-based

63. Different underlying technologies </li><ul><li>Java component (embedded, JNDI)

64. REST service

65. Web service

66. EJB </li></ul><li># of (independent) session </li></ul>

67. TITLE SLIDE: HEADLINE Presenter name Title, Red Hat Date Demo

68. Roadmap <ul><li>jBPM 5.0: Februari 2011

69. jBPM 5.1: NOW ... </li><ul><li>Improve designer to support full round-tripping

70. New Eclipse BPMN2 editor
