  1. Architecture

  2. ISL Building Blocks • Federation • Integration Layer • Provides seamless interconnection between SOA frameworks (Web Services, .NET, …) • Group • Provides visibility to agents and services • Supports one or more Habitats • Habitat • Virtual Machine • One or more on a physical device • Container for one or more services or agents • Service • A method based provider residing in a Habitat • Interacts with a source (e.g. device, database, web page, other service) • Agent • A service provider that uses asynchronous messages to communicate • BehaviorAgent contains one or more dynamic Behaviors • Behavior • Defines some of the capability of an agent

  7. Standards

  8. SCA • Component Implementation • Language independent • Implements contract of Component Type • Component Type • Services • Interfaces exposed to others • References • Interfaces that it uses • Properties • Control behavior at run-time • Component Composition and Assembly • Composite of components (SCDL file) • Wires components together and has Services, References, and Properties • Used by runtime to instantiate

  9. Component Type • XML file named Foo.componentType • Describes Services, References, and Properties • Can use Java annotations • implementation tag will introspect class file <componentType> <service name=“MortgageCalculatorService”> <interface.java interface=“mortgage.MortgageCalculator” /> </service> </componentType>

  10. Component Composition and Assembly <composite xmlns=“…” name=“MortgageComposite” > <component name=“LoanApprovalComponent”> <implementation.java class=“mortgage.LoanApprovalImpl” /> <property name=“interestRate”>7.5</property> <reference name=“CreditCheck”>CreditCheckComponent</reference> </component> <component name=CreditCheckComponent”> <implementation.java class=“mortgage.CreditCheckImpl” /> </component> </composite>
