Question

I need to lower my received sequence number for performing FIX certification to check the gap fill/resend works.

I tried editing the number but now I get EOF Exception whenever I launch my app.

The format of the sequence number file is a bit weird:

^@^C7:4

Any idea how to do this?

Thanks.

public static void main(String[] args) throws IOException {
    int senderSequenceNumber=1910;
    int targetSequenceNumber=2268;
    RandomAccessFile file  = new RandomAccessFile("C:\\filename.seqnums", "rw");
    file.seek(0);
    file.writeUTF("" + senderSequenceNumber + ':'+ targetSequenceNumber);
}
