I think you can still use ZipOutputStream though, it will only be<br class="">
blocking if the underlying Stream is blocking, so using something like<br class="">
a ByteArrayOutputStream would make the operation non blocking. If you<br class="">
want to avoid buffering the whole zip in memory you could potentially<br class="">
alternate between writing data to the ZipOutputStream and then taking<br class="">
anything written to the ByteArrayOutputStream and flushing it to the<br class="">
response channel.<br class="">
