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

BPMN 2.0
● OMG specification● Model● Notation● Execution semantics
● Understandable by all business users
● Process, collaboration, choreography● Extensible
![Page 11: JBoss jBPM, the future is now for all your Business Processes by Eric Schabell](https://reader031.fdocuments.in/reader031/viewer/2022022402/54622a75b1af9f92238b4d96/html5/thumbnails/11.jpg)
jBPM5 and BPMN2
● Focus on executable processes● Java environment● Native execution
● Subset● Common Executable ++
● High-level and domain-specific● Minimal custom extensions
![Page 12: JBoss jBPM, the future is now for all your Business Processes by Eric Schabell](https://reader031.fdocuments.in/reader031/viewer/2022022402/54622a75b1af9f92238b4d96/html5/thumbnails/12.jpg)
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>

BPEL Vs BPMN
● Red Hat does not intend to create 2 BPM solutions
● BPMN2 is the strategic direction
● BPEL requirements will be fulfilled with implementation.
● Project Riftsaw – implementation of BPEL will be included in SOA-P 5.2
● Future BPM solutions will be built on BPMN2 standards
● JBoss BPM platform is our answer to all process flow / workflow solutions

Combining processes and rules
● Integration● From loose coupling (decision services)● To advanced integration (process rules)
● Unification● Rules and processes are different types of
business knowledge assets● Tooling (IDE, repository, management)

Web based artifact management
● BRM as knowledge repository
– BPMN2 processes
– Task and process forms
● Web designer (Oryx)
● Build, deploy, test, manage and collaboration features

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