Receive file question

[jaspm2004]

Hi there, me again.

Im testing the receiveFile(file, 0, file_size) method but i cant get it working.

        // Receive the file length, in bytes
        byte[] buffer = new byte[8];
        receiver.receive(buffer);
        log("file size = " + toLong(buffer));
        long file_size = toLong(buffer);

        // receive the file...
        File file = new File("C:\\temp\\udtfile.tar.gz");
        receiver.receiveFile(file, 0, file_size);

First it was not working because seems that its not enough to create a new File(), the file have to exists before on the folder. I created the file by hand then.

Second, seems the file_size have to match the real file size? how it is this possible? i have to copy raw data to the file until reach the file_size parameter?

Ill appreciate some help on this, thanks in advance....
