I suspect you're passing in a relative filename - and chances are the working directory isn't what you expect it to be. I suggest you use an absolute filename, or find out an appropriate directory to create the file relative to.

It would also help if you didn't swallow exceptions - if there's something going wrong, the exception is trying to tell you about it, but you're ignoring it completely.
