PDA Optional Packages for the J2ME Platform
From Wikipedia, the free encyclopedia
PDA Optional Packages for the J2ME Platform JSR 75 is a specification that standardizes access in the Java on embedded devices such as mobile phones and PDAs to data that resides natively on mobile devices. JSR 75 is part of the Java Platform, Micro Edition (Java ME) framework and sits on top of Connected Limited Device Configuration, a set of lower level programming interfaces. It has 2 main components.

[edit] Personal Information Management (PIM)
The first component allows acces to the PIM or Personal information manager data on the phone, which includes personal data and the address book.
[edit] FileConnection (FC)
The File Connection Optional Package (FCOP), javax.microedition.io.file, is the other package defined by JSR 75. The FileConnection API specified in JSR 75 gives access to the local file systems on devices like PDA. It allows read and/or write access to the file system of the phone. This is needed for a java application to access images, songs, or in fact almost any file stored on the handset. In order to overcome security issues MIDlet needs to include requested file permission in its JAD file under MIDLet-Permission property.
