public class kxmlrpc_demo extends MIDlet implements CommandListener {
private List list;
private Command exitCommand;
private String[] menuItems;
private Display display;
private Alert response;
private XmlRpcClient xmlrpc;
private Vector params, xmlArray;
public kxmlrpc_demo() {
//Initialize the User Interface
menuItems = new String[] {"Timestamp", "Randomizer", "AddressBook"};
list = new List( "Select a service", List.IMPLICIT, menuItems, null );
exitCommand = new Command( "Exit", Command.EXIT, 1 );
response = new Alert("Service Return", null, null, AlertType.INFO);
response.setTimeout( Alert.FOREVER );
//Add commands
list.addCommand( exitCommand );
list.setCommandListener( this );
//obtain a reference to the device's UI

}//end startApp()
public void pauseApp() {
}//end pauseApp()
public void destroyApp( boolean unconditional ) {
//clean up
list = null;
exitCommand = null;
display = null;
}//end destroyApp
public void commandAction( Command com, Displayable dis ) {
if ( dis == list && com == List.SELECT_COMMAND ) {
switch( list.getSelectedIndex() )
case 0:
try
xmlrpc = new XmlRpcClient( "http://localhost:4116/test1Service/test1?Tester" );
params = new Vector();
String serverTime = (String) xmlrpc.execute( "sysTime.getSystemTime", params );

break;
}//end switch( list.getSelectedIndex() )
else if ( com == exitCommand ) {
destroyApp( true );
notifyDestroyed();
}//end if ( dis == list && com == List.SELECT_COMMAND )
}//end CommandAction( Command, Displayable )

Thanks in advance.
