3. OSGi is Great for SOA
Solid Foundation
 Module, Lifecycle, Service Layer
Service Composition
 Service Tracker
 Service Component Models ( Declarative Service, OSGi Blueprint )

4. The needs for BPM…
Service Component Models are great but…
 Require to write code to realize business logic
 We need to expose service through different protocols ( not
only SOAP )
Business Analyst think in term of “processes”
 Analyst/Developer gap
Making SOA Project is not only about development
 Governance & Management Tool are keypoints

5. eBPM Project
BPM Platform for OSGi services
 Equinox/Swordfish
Core Framework
 OSGi Declarative Services
 Messaging Model
 Event Admin / Distributed ( ECF )
Connectors & Services
 Expose services to external world
through “connectors”
 HTTP,SOAP,JMS,File,FTP,JDBC
 Common Services ( XSLT, Script. )
Tools
Process Modelling Tool Integration
Service Configuration/Deployment
Monitoring & Managament Tools

6. eBPM – Scope and Background
Will cover the “BPM stuff” in Eclipse SOA TLP
Creation review will be next week ( 7 April 2010 )
The initial code base come from Spagic Project http://www.spagic.org
Solid foundation based on real projects
 Healthcare ( HL7 integration )
 Italy Public Administration ( Local and Central )
 Industry
 Finance/Banking

9. Orchestration
Two ways to realize services orchestration
The orchestration engine live within the OSGi Container
 “BPM Gateway” bundle
 Based on open source process engine
( adapted to work within OSGi)
The orchestration engine embed the OSGi Container
 BPEL

10. Tools
Service Configuration Editor
 Not overlap with PDE ( it work at a different level )
 Visual Configuration of eBPM services
 Easy Extensible with extension points
Process Development Tools
 BPMN Modeler, Eclipse BPEL Designer
 Extension to easily use eBPM/OSGi service within processes
Deployment Wizard
 Provide facilities to deploy eBPM projects to the Equinox container

12. BPEL Architecture

13. Apache ODE – eBPM Integration
Based on the “Equinox ServletBridge” approach
 eBPM Client API realize the “bridge”
 Implemented as OSGi bundle
Process will use BPEL2.0 Standard Extension Syntax
 Standard Extension Implementation for ODE 2.0
 Will use the eBPM API to interact with services
