Record Management System

12 Record Management System

Overview

The most common mechanism for persistently storing data on a MIDP device is through RMS. RMS provides the capability to store variable length records on the device. Those records are accessible to any MIDlet in the MIDlet Suite, but not to MIDlets outside of the MIDlet Suite. The RMS implementation of the Motorola C370, C450, and C550 series of handsets is MIDP compliant, so there are no significant additions or changes to the MIDP specification.

Class Description

The API for the RecordStore is located in the package javax.microedition.rms.

Code Examples

The following is a code example to show implementation of opening the RecordStore. If any exception occurs it will be caught.

RecordStore

try {

System.out.println("Opening RecordStore " + rsName + " ..."); //try to open a record Store

recordStore = RecordStore.openRecordStore(rsName, true); //keep a note for the last modified time for record store

Date d = new Date(recordStore.getLastModified()); System.out.println(recordStore.getName()+"modified last time: " +

d.toString());

}

catch (RecordStoreException rse) {
