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( ..., &quot;sample.bpmn&quot;, 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”);
