J2ME

Terms Used in J2ME :        1) MIDP :  Mobile Information Device Profile. Which contains Java APIs for user network                         connections, persistence storage, and the user interface. It also has                       access to CLDC libraries                                2) CLDC :Connected Limited Device Configuration.It is a specification of a framework for Java ME                                applications targeted at devices with very limited resources such as pagers and mobile                                 phones.        3)  MIDlet:  A MIDlet is a Java app framework for the Mobile Information Device Profile(MIDP)                                     that is typically implemented on a Java-enabled cell phone or other embedded device                                      or emulator.

XML Parser

• import net.rim.device.api.xml.parsers.*;• SAXParser Parses XML documents.

SAXParserFactory A factory to configure and create SAXParser instances.

• SAXParserFactory is a manager kind of thing which maintains and reuse parsers.

Localization

• net.rim.device.api.i18n.ResourceBundle class to be imported• Provides functionality that supports the internationalization of

applications on RIM Devices.

• To files .rrh and .rrc.(resource header and resource content).

• Text translation is efficient because all of the text strings for a given locale are stored in a single file, outside your source code.

• BlackBerry Java Applications can dynamically retrieve the appropriate text to display to the BlackBerry device user, based on the locale of the BlackBerry device user.
