Although an ESB does not require a J2EE application server for its implementation, it can make extensive use of individual technologies from J2EE and J2SE.
The JBI effort will provide a specification for plugging integration components into an interoperable integration environment. This will allow JBI-compliant integration components to be plugged into an ESB infrastructure as services.
The JCA defines a standard set of interface contracts for creating adapters to connect into and interact with enterprise applications. An ESB can use JCA as a common way of plugging into application adapters through an adapter service type.
JMX provides a means by which an application can interface with a management infrastructure and management consoles. In an ESB, a JMX-based management infrastructure can manage remote services and remote configurations from anyplace that is accessible by the bus.
