3. Overview
• Key characteristics
• From Workflow to BPM
• Ready for the future?
• jBPM5: What, where?
• Eclipse Tooling

4. Key Characteristics of BPM
• Visibility
• Monitoring
• Higher-level
• Continuous improvement
• Speed of development
• Increased agility
A business process is a process that describes
the order in which a series of steps need to be executed,
using a flow chart.

5. 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

6. From Workflow to BPM
• Core engine is a workflow engine in
pure Java
– state transitions
– lightweight
– embeddable
– generic, extensible

10. 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/

11. 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>

12. Java Example
// (1) Create a new knowledge base and add process definition
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(
ResourceFactory.newClassPathResource("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”);

20. Domain-specific Processes
• Extend palette with domain-specific,
declarative service nodes
– define input / output parameters
– runtime binding

21. Human task service
• User task
• Human task
service (WS-HT)
– Task lists
– Task life cycle
• Task clients
– Task forms

22. Ready for the future?
Traditional systems have problems with
change, complexity, flexibility, data-
intensive applications, etc.
• Adaptive Case Management (ACM)
• Unstructured or non-lineair processes
• Event-driven BPM (edBPM)

23. 23
Processes + Rules + Events
