Class ServeBinaryAction

Object
  ActionImpl
      hirondelle.fish.exercise.binary.ServeBinaryAction

All Implemented Interfaces:

Action

public final class ServeBinaryAction
extends ActionImpl

Serves a simple binary file, in .rtf format.

Exercises serving a binary, non-HTML response to the user. This class generates a fixed response. In practice, it is almost always the case that the content will be generated dynamically, using the database.

This action is activated by a URL that ends in .rtf. This helps the browser confirm the content-type, and to open the appropriate helper application. See RTF Cookbook for more information on .rtf files.

See the fileupload package for a more practical example of handling binary data.
