You can use the SVG-specific JZip jar (which I got from to make svgz FROM svg, but I don’t know if you can use it for svgz TO svg.  (Maybe you can check out the full JZip projects at sourceforge which might be compatible, but I’ve not looking into this myself.)  The compression format is essentially gzip, so you can just use gzip to decompress (when doing this I’ve had to rename the file first, from abc.svgz to abc.svg.gz so that gzip will recognize it).  The preferred way to compress is with the JZip jar though, I believe.
