Voice recording problem...Please..

[brokenlink911]

Can any body pls give me an idea on recording the client's voice from the server side...
The best solution that i can get is...i can record the client's voice into a file...but once i opened the file manually, it does not contain any voice....just "SsSSSsssSsSSsHHHhHhhHHhh"..
Im using Java Sound..by using the TargetDataLine in the client pc, there no voice can be stored.....but the client's voice can be played in the Server's speaker.....
So, how store the client's voice played by the server's speaker into a sound file that will be placed on the server......

Help....




thanks in advance

Do you want to stream the voice from the client side to the server side?

[brokenlink911]

I think i ve got the stream from the client....
the problem is ..the voice stream of the client cannot be recorded in the server side...Actually what i want is to record the voice conversation between the client and the server....
So, do u hav any idea on how to do it...?
