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. )

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 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
