What is the FTP BC?

Binding components are used to send and receive messages via particular protocols and transports. They serve to isolate the JBI environment from the particular protocol by providing normalization and denormalization from and to the protocol-specific format, allowing the JBI environment to deal only with normalized messages - JBI Specification 1.0 (JSR 208).

Open ESB FTPBC is JSR 208 compliant, it provides a message transportation via FTP protocol so that services (which comprise operations) can be defined using WSDL and bound to FTP as its underlying message transportation protocol, other components in a JBI environment (for example, an SE can further orchestrate the services consumption and provision).

FTP BC implements all required BC interfaces in JBI specification so that it can be deployed and run in any JBI compliant target environment.

To facilitate the process of service definition and binding, the implementation also comes with a design-time component, a NetBeans module which makes WSDL authoring and FTP binding a convenient process in NetBeans IDE.
