J2ME Exception - PLEASE HELP

[cpptutor2000]

I am bit of a newbie to J2ME, and I am trying to create a simple
metronome application. I am using Java 1.4.2.16 along with the Sun
WTK.
I am getting an exception as:

java.lang.IllegalArgumentException: type media does not have subtype
Tone

Any hints would be extremely useful. Thanks in advance for your help.

Any hints would be extremely useful.

I would clean up the program language before posting. It is not clear
if you are seriously asking for help or just disguising a **** you.
