How do you invoke an endpoint through the ESB

External services that want to call an esb can use several transports (binding components). The transport layer and the protocol layer can be decoupled : a binding component will take care of the transport layer, but may let the protocol layer be handled by a service engine in the jbi container. The most useful binding components are jms, http, email and jabber. Soap can be used as a protocol, but this is not mandatory.
