OSGi & BPEL

Agenda
1. Context2. eBPM Project3. Orchestration Solutions within eBPM4. BPEL Integration5. Demo
OSGi & BPEL | © 2010 – Andrea Zoppello made available under the EPL v1.0
OSGi is Great for SOASolid 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 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

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. )
ToolsProcess Modelling Tool IntegrationService Configuration/DeploymentMonitoring & Managament Tools

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

eBPM Core Framework – Class Diagram

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

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

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
