How to read a .gz file that's stored on a remote server?


Would anyone be able to guide me with how to read a .gz file that's stored on a remote server?  I know how to read a regular file using a URLConnection etc. but I'm not sure how to read from a .gz file.

Thanks for your help

You need to use the GZIPInputStream to read it.

InputStream gz = new GZipInputStream(url.openStream());

would be the heart of it

GZipInputStream gz = new GZipInputStream(<inputstream from url>);

Typo. SHould be

InputStream gz = new GZIPInputStream (url.openStream());
Connect using the normal way only, using URLConnection but wrap the inputstream you get

using:  GZIPInputStream gis = new GZIPInputStream(urlconnection.getInputStream());

After I get the GZIPInputStream, how would I read it line by line?

(For regular files I use BufferedReader readLine() - is there a corresponding idea of a "line" using GZIPInputStream read()?)

oh, I think I can just wrap the BufferedReader
pw05 - any reason why my answer was ignored?

CEHJ - I didn't try url.openStream - I thought it had to be urlconnection.getInputStream

sorry about that
No, but never mind ;-)
