As part of the IAF distribution, Apama includes the JFileTransport transport layer plug-in, in the samples\iaf_plugin\java\simple\src directory.
The JFileTransport plug-in can read and write messages from and to a text file, and it is recommended that developers examine this sample to see what a typical transport plug-in implementation looks like.
See IAF samples for more information about this sample. The section The File Transport plug-in describes how the JFileTransport plug-in can be used in practice.
