What is the File BC?
File BC provides a comprehensive solution as a transport to interact with the file system within a JBI environment.
Looking at what File BC does at a very high level: On the server side, File BC polls for inbound messages, stored in file(s), in a specified directory. On the client side, File BC puts messages into file(s) in a designated directory.
The design time component of File BC is a Netbeans module that provides plug-in to NetBean’s project system and thus defines how File binding can be used. The runtime component implements all required component interfaces in JBI specification and provides the functionality to act as a proxy to services enabled using the file protocol.
Using the File BC
- Using the File Binding Component (Guide)
- Working With the File Binding Component (Tutorial)
- Video Presentation
: Operation with In/Out Messages of complex type. This video demonstrates how to define request-response operations using FILE BC and FTP BC with In/Out messages for FILE service and FTP service having complex type defined by a XSD – Greeting.xsd - User Guide
- Dynamic Binding Using NM Properties
- Using File Binding in Glassfish ESB v3
– this write up shows how to compose an v3 Integration Application with IFL and File/FTP services using IDE tooling and webui as well.
