You cannot do it this way. FileWriter can only append to a file, rather than write in the middle of it - You need RandomAccessFile if you want to write in the middle. What you do now - you override the file the first time you write to it (and it gets empty - that's why you get the exception). You can create FileWriter with append flag set to true - but this way you would append to a file rather than write in the middle of it.

I'd really recommend to write to a new file and then rename it at the end.
