Do you mean, something like GZIPInputStream?

InputStream is = ....
InputStream gis = new GZIPInputStream(is);

yes, I guess i did. I was assuming I needed to perform operations on the GZIPInputStream object. Sometimes the simplest solution is the hardest to see. – smp7d Sep 21 '11 at 15:34
@Dirk, Thanks for the link. I have a helper method that looks at the end of the filename and uses GZIPInputStream or GZIPOutputStream as appropriate. You may want BufferedInputStream before the GZIP as well. – Peter Lawrey Sep 21 '11 at 15:39
