● A standard way to add new
functionality to an existing
platform
● Standard Installation and life
cycle for components
● Standard WSDL based
communication across
components
● Standard deployment model for
all components
● Result of the experience we
had with our own Products:
Integration Server EAI,
SeeBeyond ICAN

33. Open ESB: An Extensible Platform

34. JBI in a Nutshell
ESB Container Foundation
Service Engines
(SEs) as logic
Orchestration Transformation containers
J2EE Platform
(BPEL) (XSLT)
Management

Normalized Message Router
JBI
Core
• The “JBI Bus”: a fast, reliable, in-memory
Services
messaging bus
• Mediates all message exchanges between
WS-I Basic AS2 JMS consumers and providers
SOAP • Message payloads are opaque data sent along to
Binding Components the receiver (no canonicalization)
(BCs) J2EE™ PlatformNormalization not performed when consumer and
•
as proxies to outside world provider in same JBI container

• JAX-RS
> RESTful Web Services
> RI developed in // with Spec:
http://jersey.dev.java.net
> Expose POJO as RESTful resources
> High-level declarative programming model
> Flexible typing, runtime does common conversions
> Pluggable types, containers, and resolvers
