72 J2ME Wireless Toolkit User’s Guide • October 2004

Each subdirectory of filesystem is called a root. The J2ME Wireless Toolkit

provides a mechanism for managing roots. While the emualtor is running, choose

MIDlet > External events from the emulator window’s menu. You’ll see a utility

window for adding and removing roots.

FIGURE 37 Managing filesystem roots

The mounted roots and their contents are available to applications using the

FileConnection API.

To add a new root directory, click on Mount New... and fill in a name for the

directory. To make a directory inaccessible to the FileConnection API, select it in

the list and click Unmount.

10.2 The PIM API

The J2ME Wireless Toolkit emulator stores contact, calendar, and to-do information

in standard files on your desktop computer’s hard disk. All information is stored in

{toolkit}\appdb\{skin}\pim. This directory is shared by all running emulators. Lists

are stored in subdirectories of the contacts, events, and todo directories. For

example, a contact list called Contacts is contained in

{toolkit}\appdb\{skin}\pim\contacts\Contacts.

Inside the list directory, items are stored in vCard or vCalendar format (see http:/

/www.imc.org/pdi/). Contacts are stored in vCard format, while calendar and

to-do items are both stored in vCalendar format.
