No, I was just saying how I did it. As I recall--it's been several years--I first used OpenCSV but switched to Apache's CSV because it also had a tab delimited option (though I guess you can do the same thing with OpenCSV by changing the delimiters).
If your file is empty, I'd check your file calls, not the CSV library: Is the file opened for writing, is the file handle properly passed to the library, is the data still there to write, is the output properly flushed, and is the file closed. I'd write something to the file before and after my CVS calls to see if anything gets written. And I'd check the file on the server, not just what my servlet returns.
