5. Context JBI
JBI is an ESB (Enterprise Service Bus)
Fundamental characteristics
Layer on top of an enterprise messaging system
Basic connectivity (Web Services, J2EE, JMS)
Service oriented architecture
Support for distributed deployments and management
Key, Added value characteristics
Robustness
Scalability
Security
Development / deployment toolset

6. Context JBI
JBI overview
Java Business integration: JSR 208
Plug-in model
Messaging model
Pierre Garcia ( INRIA SARDES ) JOnES - Revue annuelle 11/04/2007 6 / 22

7. Context JBI
JBI architecture
1 JBI environment = 1 JVM
Limitation: no description of communications between two JBI instances

9. Context PEtALS
PEtALS: a distributed implementation of JBI
Distribution in PEtALS is accomplished using:
A naming service: JNDI
One communication middleware (MOM): JORAM

DREAM: a component framework to build MOMs
Allows building arbitrarily complex MOMs
Built upon the FRACTAL component model
Comprises:
DREAM Core: abstractions found in a MOM
DREAM ADL: tools to deploy a MOM
DREAM Library: set of components to build MOMs

13. DREAM in the JOnES project Introduction
Goals
Offer different ways to communicate between PEtALS environment. The
incremental steps are:
Pragmatic approach: pre-defined connectors
Standard approach: connectors defined using the WSDL policy framework

Choice of the Transporter
Tag contained in messages
Global description of available transporters
Limitations:
Transporters potentially useless
Distribution no more transparent to JBI components

20. DREAM in the JOnES project Current work: Transporter Factory
Transporter Factory
Uses a static description of available transporters
Allows customizing PEtALS and using appropriate transporters
Distribution still non transparent to JBI components
Limitation: configuration of PEtALS is more complex
