bpel & osgi at eclipsecon 2010
DESCRIPTION
Presentation supporting the speech of Andrea Zoppello, Spagic Architect, at EclipseCon 2010. The speech was centred around the integration of the Open Source BPEL engine Apache ODE with OSGi services, within the embedded container Equinox. The presentation refers to the core of Spagic platform, with a particular focus on the new orchestration features for OSGi services and connectors and on the support offered to the governance of SOA projects through the web console Spagic Monitor.TRANSCRIPT

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

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

eBPM ProjectBPM 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. )

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 comes from Spagic Project http://www.spagic.org
Solid foundation based on real projects
� Healthcare ( HL7 integration ) � Italy Public Administration � Industry� Finance/Banking

Orchestration
Two ways to realize services orchestration
The orchestration engine lives within the OSGi Container� “BPM Gateway” bundle
� Based on open source process engine ( adapted to work within OSGi)
The orchestration engine embeds the OSGi Container� BPEL

Tools
Service Configuration Editor� Does not overlap with PDE ( it works 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 services within processes
Deployment Wizard� Provides facilities to deploy eBPM projects to the Equinox container

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