SMS Application probs

[ram]

Hi

Im build a sms application using j2me.
I have gone through Java world's Push messages that automatically launch a java mobile application its good

indeed and i started implementing it.
Im using Wireless Toolkit 2.1 for developing application and by using Nokia Application suite im downloading

the jar file into NOKIA 6630 mobile which we r using these days for demo.
I have used the client side MIDlet using push registry feature code and generated jar file and dumped into my

mobile. The downloading and installation is successful but im unable to run the application its just appearing

a glance and closing.
Could anyone suggest me on this, why it is happening like this and do i want to change my code or settings in

Wireless toolkit. This is very imp to me pls respond me in detail and reg server side application pls suggest

me some more details.
If i can get sources from any, pls mail them to remo1431442@yahoo.com

Thanks & Regards,
