I have created the app but don't know from where i get TOKEN_KEY &
TOKEN_SECRET plz help.....

If this is an offsite app, then you will get these values from the access token request call, see the sequence here (item 4): http://wiki.developer.myspace.com/index.php?title=OAuth_REST_API_Usage_-_Authentication_Process

Let me know if this helps. You need these values to sign subsequent requests to prove you are the legitimate requestor.

thanks,

Joel
