Client and services connect to the
container via binding components or can be hosted inside the container as part of a
service engine.

Java Business Integration (JBI) is a Java standard (JSR 208) for structuring
business integration systems along SOA lines. It defines an environment
for plug-in components that interact using a services model based directly
on WSDL 2.0.
Project OpenESB is an open-source implementation of JBI. It extends the
JBI specification by creating an enterprise service bus (ESB) from multiple
JBI instances. The instances are linked by a proxy-binding based on JMS.
This allows components in separate JBI instances to inter-operate in the
same fashion as local ones.
JBI defines standard packaging for composite applications that are composed
of service consumers and providers. Individual service units are deployable to
components; groups of components are gathered together into a service assembly.
The service assembly includes metadata for bonding the service units together, as
well as bonding service units to external services. This provides a simple mechanism
for performing composite application assembly using services.

based business processes.
