file trasferring issue

hi all,

i m facing some problem on file transferring .

u can download my current application from here ,

4shared.com - online file sharing and storage - download pairsGame_run.rar

on myCanvas.java file , there are some cases r there
in that

case screen_sendFile:
drawSendFile(g);
//drawServerClientMenu(g);
break;
case screen_howToSendFile:
//drawHowToSendFile(g);
drawServerClientMenu(g);
break;
}
is not working Properly
how i can configure my file transfer part with this

( i have seen Example on blue tooth MIDP(image sending) from Netbneans6.0 )
the same concept u can say same code i m using on my file transferring part.

but i m not getting how call that on my current application .

for file transferring i m included this file
BTImageClient.java,
BTImageServer.java,
GUIImageClient.java,
