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) {
