jBPM5 in action - a quickstart for developers
- 2. jBPM5 in Action: A Quickstart for Developers Kris Verlaenen jBPM5 Lead Engineer
- 4. Why BPM?
- 5. Getting started with jBPM5
- 7. Integrating in your architecture
- 9. Console
- 10. 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
- 12. Monitoring
- 16. Getting started with jBPM5 !
- 18. targeting developers and business users
- 19. collaboration, management and monitoring using web-based consoles
- 20. powerful rules and event integration
- 22. lightweight
- 23. embeddable
- 24. generic, extensible Core Engine
- 25. Core Engine Knowledge Base Stateful Knowledge Session Process Definition Process Instance
- 26. 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 >
- 33. …
- 34. 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”);

- 37. runtime binding
- 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); } }
- 43. Human Task Service public void start( long taskId, String userId, .. ) public void stop( long taskId, String userId, .. ) public void release( long taskId, String userId, .. ) public void suspend( long taskId, String userId, .. ) public void resume( long taskId, String userId, .. ) public void skip( long taskId, String userId, .. ) public void delegate( long taskId, String userId, String targetUserId, .. ) public void complete( long taskId, String userId, ContentData outputData, .. )
- 44. Testing, debugging, deploying, etc.
- 45. Model Deploy Execute Monitor Analyze Life Cycle Mining Analysis Optimization Simulation Testing Design Monitoring Reporting Execution Integration Deployment Management Audit Human Interaction Collaboration
- 46. JUnit Testing public class MyProcessTest extends JbpmJUnitTestCase { public void testProcess() { StatefulKnowledgeSession ksession = createKnowledgeSession ("sample.bpmn"); ProcessInstance pI = ksession. startProcess ("com.sample.bpmn.hello"); assertProcessInstanceCompleted (pI.getId(), ksession); assertNodeTriggered (pI.getId(), "StartProcess", "Hello", "EndProcess"); } }
