This example decompresses a gzip compressed file with java.util.zip.GZIPInputStream . The input is assumed to be Base64 encoded after being gzipped (such would be the case when binary data is transmitted within an XML file).
You don't need the Base64InputStream if the data is not Base64 encoded.

Using the Sun BASE64Encoder :

import sun.misc.BASE64Encoder...
However, the Sun encoder is awfully slow. The Apache encoder is a lot faster. Here's the code with Apache encoder:
