Hi everyone.I'm basically new to java but with the help of this forum i have managed to come up with the folowing code(see attachment).I'm a bit stuck now and i need help.

PROBLEM STATEMENT
When the login button(submit) is clicked i want the program to connect to a db(which i have already acomplished),and after authentication i want it to dispose the full screen frame,set timerframe visible and launch the count down timer.when the counter reaches zero,the timerframe must dispose and the the full screen frame set visible.
i'm using the j2sdk1.4.2_04 version.

P.s Feel free to alter or add anything to the existing code.
coments will be appreciated.
Thanx in advance
