Example: Notification
class NotificationHandler implements WorkItemHandler {
    public void executeWorkItem(WorkItem wI,
                                 WorkItemManager manager) {
        String from = (String) wI.getParameter("From");
        String to = (String) wI.getParameter("To");
        String m = (String) wI.getParameter("Message");
        // send email
        EmailService service = ...;

Ready for the future?

Traditional BPM systems have problems
 with change, complexity, flexibility, data-
        intensive applications, etc.



 • Adaptive Case Management (ACM)
 • Unstructured, non-lineair or flexible processes
 • Event-driven BPM (edBPM)
Motivation

A business solution usually involves the
  interaction between these technologies.

jBPM, open source BPM

  • 1. jBPM5: Bringing more Power jBPM, to your Business Open Source BPM Processes Kris Verlaenen jBPM Project Lead June, 2012 1
  • 2. jBPM Overview • jBPM Project • jBPM walkthrough • Roadmap
  • 3. What is BPM? Business Process Management A business process is a process that describes the order in which a series of steps need to be executed, using a flow chart.
  • 4. Why BPM? • Visibility • Continuous improvement • Monitoring • Speed of development • Higher-level • Increased agility
  • 5. jBPM Project • (Executable) business processes – light-weight, native BPMN2 engine – from embedded to as a service • Entire life cycle • Both developers and business users • Advanced, adaptive processes
  • 6. Life Cycle Business Analyst Model Developer System Administrator Monitor BPM Deploy Execute End User
  • 7. End User r ito on Your jBPM Console Application M e Core Services ut ec Your Core History Task Ex Services Engine Log Service Rules y lo ep Guvnor D Repository el Web-Based Eclipse Editor od Designer M Developer Business Analyst
  • 8. Key Characteristics • Open-source, lightweight • Native BPMN 2.0 • High-level business processes • Business user & developer collaborate • Advanced, adaptive processes • Modularized, pluggable, standards
  • 9. Advanced, adaptive processes • (One of the) most advanced open- source BPMN2 engine • Adaptive, ad-hoc, dynamic processes • Integration and unification with business rules and complex event processing
  • 10. jBPM Walkthrough • Core engine • From Workflow to BPM • Extra features • Social, Cloud and Mobile
  • 11. Core Engine • Core engine is a workflow engine in pure Java – state transitions – lightweight – embeddable – generic, extensible Core Engine
  • 12. Core Engine Stateful Knowledge Knowledge Base Session Process Process Definition Instance
  • 13. Java Interface ProcessRuntime interface • startProcess(processId) • startProcess(processId, parameters) • signalEvent(type, event) • signalEvent(type, event, instanceId) • abortProcessInstance(instanceId) • getProcessInstance(instanceId) • …
  • 14. 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”);
  • 15. From Workflow to BPM
  • 16. From Workflow to BPM XML Core Engine BPMN 2.0
  • 17. BPMN 2.0 <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>

  • 19. jBPM Eclipse Plugin • Developer-focused • Features: – Wizards, runtimes, perspective – Graphical editor – Testing and debugging – Service repository, generators – Guvnor integration
  • 20.
  • 21. Web-based Designer • Business User-focused • Features – Graphical Editor – Visual validation – Service repository, generators – Guvnor integration • Based on Oryx Designer – JavaScript, JSON
  • 22. From Workflow to BPM JPA Persistence XML JTA Trans- actions Core Engine BPMN 2.0
  • 23. Persistence and Transactions • Persistence (JPA, pluggable) – Runtime persistence – History logging – Services • Transactions (JTA, pluggable) – Command-scoped – User-defined
  • 24. Persistence • Core engine no persistence • Macro transactions • Binary persistence of runtime data • Separation of history information • External services – using work items, async – independent task service
  • 25. ProcessInstance startProcess Process 1 active d/m/yy hh:mm ... Runtime Engine addTask Task 1 Task1 sales ... Service Tasks 2 Task2 HR ... Task Task
  • 26. ProcessInstance Process 1 active d/m/yy hh:mm ... Runtime Engine complete Task 1 Task1 sales ... Service Tasks 2 Task2 HR ... Task Task complete

  • 28. From Workflow to BPM Persistence XML Trans- actions Core Engine BPMN 2.0 History Events Log Management Console BAM
  • 29. Console • Web-based management • Business user • Features – Process instance management – User task lists / forms – Reporting
  • 30.
  • 31.
  • 32.
  • 33. Console • GWT • Generic BPM console – jBPM integration code • REST API • One embedded session – Persistence, history logging • Eclipse BIRT reporting: custom reports
  • 34. From Workflow to BPM Persistence XML Trans- actions Core Engine BPMN 2.0 Events Domain-specific Integration Processes Human Task ESB Service
  • 35. Domain-specific Processes • Extend palette with domain-specific, declarative service nodes – define input / output parameters – runtime binding
  • 36. Domain-specific Processes • Why? • Other examples – Domain-specific – Human task – Java method – Declarative – WS, Rest – High-level – Email, Twitter – Context-defined – FTP, RSS, Jabber – Finder, Exec, Archive – Google Calendar Repository ! – YOUR SERVICES !
  • 38. Example: Notification [ [ "name" : "Notification", "parameters" : [ "Message" : new StringDataType(), "From" : new StringDataType(), "To" : new StringDataType(), "Priority" : new StringDataType(), ], "displayName" : "Notification", "icon" : "icons/notification.gif" ] ]
  • 39. Example: Notification class NotificationHandler implements WorkItemHandler { public void executeWorkItem(WorkItem wI, WorkItemManager manager) { String from = (String) wI.getParameter("From"); String to = (String) wI.getParameter("To"); String m = (String) wI.getParameter("Message"); // send email EmailService service = ...; service.sendEmail(from, to, "Notification", m); manager.completeWorkItem(wI.getId(), null); } }
  • 40. Human task service • User task • Human task service (WS-HT) – Task lists – Task life cycle • Task clients – Task forms
  • 41. Human Task Service • Independent, pure Java implementation • Different underlying technologies – Local – Apache Mina, HornetQ, JMS • I18N, calendar, deadlines, escalation • UserGroupCallback
  • 42. SwitchYard Lightweight service delivery framework providing full life cycle support for developing, deploying, and managing service-oriented applications • SwitchYard BPM component
