12. ESB Definition
There is NO J2EE-like specification with a TCK that can define and validate an ESB like there is for App Servers.
ESBs are categorized by their capabilities – some come from a heritage of EAI and others of MOM.
Capabilities:
Message delivery
Transport protocol mediation
Event capture
Intelligent routing
Orchestration
Transformation
BPM
Adapters
And much, much more…

15. Action Pipeline (in a Service)
Actions are reusable mediation components that can be chained together to form the capabilities of a registered service. Actions can be dynamically added/removed at runtime.

19. Content Based Routing Engine
Currently based on JBoss Rules – supports XPATH DSL
Access to the complete Header and Body/Contents for evaluation
Zero to many destinations
rule "Routing Rule using XPATH Greater"
when
xpathGreaterThan "50.0"
then
Log : "Really It's EXPRESS Shipping";
Destination : “express";
end
rule "Routing Rule using XPATH Less"
xpathLessThan "50.0"
Log : "Really It's NORMAL Shipping";
Destination : “normal";
Destination is determined by the jboss-esb.xml

20. Load Balancing & Fail-Over
The same discount_service.esb can be deployed to multiple ESB instances/nodes. Each one is a new EPRs in the registry. The routing engine is clever enough to load-balance and fail-over between the various EPRs. Should no EPR be available, it will scheduled the message for redelivery, waiting N seconds and retrying all possible EPRs found at that time.

21. Load-Balancing Demo

22. Deployment Options
1) ESB “within” an Application Server – Users have existing investments in the J2EE/Java EE App Servers and wish to run the ESB as a set of components in that App Server.
JBoss ESB can run “within” the JBoss Enterprise Application Platform 4.2
2) ESB “beside” an Application Server – Users wish to leave their existing application server environments untouched but still add mediation, SOA & integration capabilities.
JBoss ESB has its own lightweight engine/container for the hosting mediation services. It can run “beside” your existing middleware from your vendor of choice.
3) ESB “standalone” in a J2SE environment – this option is primarily for development & testing purposes

23. Management & Monitoring
4.2 Release is focused on JMX instrumentation, the ability to monitor the health and load of every distributed service as well as start, stop & restart them remotely.

An ESB Service is visible in the UDDI registry automatically. A single ESB Service may or may
not expose a WSDL. It may use out-of-the-box actions, custom actions and/or consume external
services from various sources. Focus on the reuse of existing infrastructure and assets.
