File System

Sun's file system service provider supports storing Java objects in the file system. Specifically, it supports the binding of Referenceable objects. Such objects are stored as a set of properties in a file called .bindings. The parent directory that contains this .bindings file is the parent context of these bindings.

For example, if you have a file directory called food, then you can add a binding to it as follows:

ctx.bind("food/fav", new Fruit("orange"));

The binding for "fav" will be stored in the file food/.bindings. You can subsequently look up the object

Fruit f = (Fruit) ctx.lookup("food/fav");

See The Basics trail for more examples.
