  • jBPM5 : Are your business processes ready for the future? Kris Verlaenen Core Developer
  • Overview
    • Key characteristics of (j)BPM
    • From Workflow to BPM
    • Ready for the future?
    • jBPM5: What, where?
    • Roadmap
  • Key Characteristics of 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 Example
  • Key Advantages of BPM
    • Visibility
    • Monitoring
    • Higher-level
    • Continuous improvement
    • Speed of development
    • Increased agility
    • ...
  • Key Characteristics of jBPM5
    • Open-source business process management project offering:
      • generic process engine supporting native BPMN 2.0 execution
      • targeting developers and business users
      • collaboration, management and monitoring using web-based consoles
      • powerfull rules and event integration
  • From Workflow to BPM
    • Core engine is a workflow engine in pure Java
      • state transitions
      • lightweight
      • embeddable
      • generic, extensible
    Core Engine
  • Core Engine Knowledge Base Stateful Knowledge Session Process Definition Process Instance
  • Java Interface
    • ProcessRuntime interface
    • startProcess(processId)
    • startProcess(processId, parameters)
    • signalEvent(type, event)
    • signalEvent(type, event, instanceId)
    • abortProcessInstance(instanceId)
    • getProcessInstance(instanceId)
  • From Workflow to BPM Core Engine
  • From Workflow to BPM Core Engine BPMN 2.0 XML
  • BPMN 2.0
    • OMG standard that defines
      • Graphical notation
      • Process definition format (XSD / XMI)
      • Execution semantics
    • Focus on executable processes
    • Extensible + Interoperability !
    • http://www.omg.org/spec/BPMN/2.0/
  • BPMN 2.0 Example < definitions ... > < process id=&quot;com.sample.bpmn.hello&quot; name=&quot;Hello World&quot; > < startEvent id=&quot;_1&quot; name=&quot;StartProcess&quot; /> < sequenceFlow sourceRef=&quot;_1&quot; targetRef=&quot;_2&quot; /> < scriptTask id=&quot;_2&quot; name=&quot;Hello&quot; > < script >System.out.println(&quot;Hello World&quot;);</ script > </ scriptTask > < sequenceFlow sourceRef=&quot;_2&quot; targetRef=&quot;_3&quot; /> < endEvent id=&quot;_3&quot; name=&quot;EndProcess&quot; /> </ process > </ definitions >
  • Java Example // (1) Create knowledge base and add process definition KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newClassPathResource(&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”);

  • From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions Events Integration Domain-specific Processes Human Task Service ESB
  • Domain-specific Processes
    • Extend palette with domain-specific, declarative service nodes
      • define input / output parameters
      • runtime binding
  • Human task service
    • User task
    • Human task service (WS-HT)
      • Task lists
      • Task life cycle
    • Task clients
      • Task forms
  • Ready for the future?
    • Traditional 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)
  • Processes + Rules + Events
  • Flexible processes

  • Misconceptions
    • For developers only?
      • Targeting business users as well
    • Proprietary, not standards-based?
      • BPMN2, WS-HT, JPA, JTA, BPAF, etc.
    • Low-level, technical details?
      • Domain-specific nodes
    • Not flexible?
      • Processes + Rules + Events
  • jBPM5 Roadmap
    • jBPM 5.0 snapshot releases available
    • Beta before the end of the month
    • Final release of 5.0 before the end of the year
    • jBPM 5.x
      • Business Activity Monitoring
      • Service Orchestration
