7.1. Bundle’s storage area

The OSGi framework provides an isolated persistent storage area for each bundle. This area can be manipulated through the usual java.io.File abstraction. Through this interface, a bundle can read and write files and manipulate directories.

As you go through this listing, keep in mind that we’ll look into simpler and more efficient ways of persisting data later on in this chapter.
