Level: Advanced Contributors: IBM 28 May 2004 The PDA Optional Packages provide a means to access native Personal Information Manager information (PIM) and File Systems in J2ME configurations. Personal Information Managers typically provide Calendaring, Contacts and ToDos.
Overview
As a co-spec lead of JSR-075 PDA Optional Packages, IBM helped define and specify two optional packages in the J2ME space. The first optional package
provides API to access the underlying Personal Information Manager (PIM) implementation on any J2ME device compliant with the specification. These APIs
expose Events (Calendar Entries), Contacts (Name and Address') and ToDos (Prioritized tasks) in a flexible cross-platform manner.
The second optional package is the FileConnection APIs. The primary goal of the FileConnection APIs is to provide access to file systems on devices
and/or mounted memory cards.
Details
IBM also had the responsibility of implementing the Technology Compatibility Kits (TCKs) and Reference Implementations (RIs) for both optional packages. The
Reference Implementations target the PocketPC operating system as an example of one mobile device with both a native PIM and complex File System implementation. The
RIs require the J9 Java Virtual Machine for the PocketPC. The specific version is outlined in the RI documentation.
In order to certify any implementation of the JSR-075 optional packages, IBM provides two TCKs (one for each optional package). Each TCK consists of a set of tests that must be run in order to claim compliance with either optional package. The TCK Harness requires only a Java Runtime Environment (JRE) or J2ME Certified Foundation
VM and Class library on the Windows platform.
