i don't have acces to the source folder.further if i check the filesize (file.length()) it is constant through out the transfer.

You can't tell if it's complete with certainty unless you know the source file size. When/if you do, you can compare the size as i mentioned.
As i said my friend is copying the file manually.I have a thread which monitors the specified folder.

Actually you didn't mention anything about manually. There is no way to know unless you somehow store the file's size in the file itself
I have written following snippet and it worked but i don't know whether its a proper way to do it.
public static void main(String args[]){
boolean flag = true;
while(flag){
File file = new File("XXX.xxx");
if(file.exists()){
BufferedReader br;
try {
Thread.sleep(1000);
br = new BufferedReader(new FileReader(file));
while(br.readLine() != null){
}
System.err.println("File Copied..");
flag = false;
} catch (Exception ex) {
System.err.println("File is Getting Copied..");
}
}
}
}

You might try obtaining a lock on the File. It shouldn't let you if it's being written to
yes you r write..but is there any harm in acquiring a lock..
actually windows(dnt know bout linux) locks the file while copying it and dosent release the lock untill an unless it copies the file completely..i am just exploiting it..
thanks for suggesting a better way of accquiring a lock

None. As soon as you get it you can release it in a finally block
None. As soon as you get it you can release it in a finally block
so that means i can figure out whether file is getting tranfer or trasnferd completely using lock method.
do you think is there any other mechanism to do so...
