problem with scope
you're declaring and initializing A within your try block.
put the A.play();
call also in the try block

i have somewhere that applet supports only ".au" files. is it true ?? and should i given full path or only the name of .mp3 file in URL ?

very well possible.
playing .mp3 files is not standard supported in Java.
if you want to play .mp3 files, you can use (for instance) JMF (Java Media Framework), or, what I would recommend, since it's quite easy and all you need to do is add a single .jar file to your classpath, the jLayer library which you can find here.
