Create a TAR File (tarball) using Coldfusion\Java on a windows server

I need to create a TAR file containing multiple files on a windows server using Coldfusion\Java. I have found lots of examples of unpacking them, but very little on creating them. I found this example of using gzip to add some text to a file and that works, but I need to add files. I'm also not 100% sure that gzip is the same thing as building a tarball. This project was assigned to me with a very short turn-around and I'm spinning my wheels so any help in the right direction is greatly appreciated:

    
<cfset lineBreak = chr(13) & chr(10) />
    <!--- open the sitemap file --->
    <cfset tarFilePath = "#application.imageingFolder#DTSimages\Pending\tiff.gz" />
    #tarFilePath#
    <!--- create streams --->
    <cfset outputStream = CreateObject("java", "java.io.FileOutputStream").Init(
    			CreateObject("java","java.io.File").Init(tarFilePath)) />
    <cfset gzipStream = CreateObject("java", "java.util.zip.GZIPOutputStream").Init(outputStream) />
    <cfsavecontent variable="siteMapHeader"><?xml version="1.0" encoding="UTF-8"?>
    <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
    	xmlns:image="http://www.sitemaps.org/schemas/sitemap-image/1.1"
    	xmlns:video="http://www.sitemaps.org/schemas/sitemap-video/1.1">
    </cfsavecontent>
    <cfset siteMapFooter = "</urlset>" />
    <cfset gzipStream.write(ToString(siteMapHeader).GetBytes()) />
    
    <cfset gzipStream.close() />
    <cfset outputStream.close() />
