See what you can do with Jar.exe.

See http://mindprod.com/jgloss/zip.html
for how to write some code to unpack a zip.

Here is a sample of the sort of thing you need:

/**
* Unpack one zip file, and put all its contents into the target
directory.
* It may contain some deadwood, but so long as we process zips in
the
* proper order the deadwood will be over written.
*
* @param zd
* Which zip file to unpack.
* @throws IOException
*/
public static void unpackOneZip ( MiniZD zd ) throws IOException
{

// can't use ZipInputStream, since getSize would fail
File zf = new File( zd.getZipFilename( ZD.ON_TARGET ) );
ZipFile zip = new ZipFile( zf );
// for each element in the zip
// can't use for:each, only works with Iterator not
Enumeration.
for ( Enumeration e = zip.entries(); e.hasMoreElements(); )
{
ZipEntry entry = (ZipEntry)e.nextElement();
String elementName = entry.getName();
Replicator.doing( "unpacking: " + elementName );
// inside zip, uses / names.
File elementFile = new File(
ConfigForReceiver.RECEIVER_BASE_DIR,
elementName.replace( '/', File.separatorChar ) );
IO.ensureDirectoryExists( elementFile.getParent() );
// test for deleted marker, possibly null
if ( "deleted".equals( entry.getComment() ) )
{
elementFile.delete();
StatsForReceiver.deletedFilesCount++ ;
}
else
{
ft.copy( zip.getInputStream( entry ), elementFile );
elementFile.setLastModified( entry.getTime() );
StatsForReceiver.receivedFilesCount++ ;
}
} // end for each element in the zip

zip.close();
} // end unpackOneZip
