    BufferedInputStream entryStream = new BufferedInputStream( is, 2048);
    int count;
    while ( ( count = entryStream.read( data, 0, 2048) ) != -1 )
    {
        zos.write( data, 0, count );
    }
    entryStream.close();
    zos.close();

    return new ByteArrayInputStream( bos.toByteArray() );
}
