Track completed downloads from glassfish

I want to be able to track completed downloads served by my glassfish server. I couldn't find a 100% correct solution using servlet life cycle listeners. Does anyone have a better idea?

Put a try-catch on IOException while serving the file download. If it's thrown, then serving the file download has failed.

E.g. in a custom file servlet:

try {
    response.getOutputStream().write(...);

    // Success!
} catch (IOException e) {
    // Fail!

    throw e;
}

Or in a servlet filter which is mapped on the appropriate URL pattern matching file downloads:

try {
    chain.doFilter(request, response);

    // Success!
} catch (IOException e) {
    // Fail!

    throw e;
}
