Sitecommand in org.apache.commons.ftp against a mainframe - has file already been uploaded

I have this

            try {
                  siteCommand = "LRECL=" + lrecl;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = "BLOCKSIZE=" + blksize;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = "RECFM=" + recfm;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = "VOLUME=" + theVolume;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = spaceType;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = "PRIMARY=" + primarySpace;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  siteCommand = "SECONDARY=" + secondarySpace;
                  ftpReply = ftp.site(siteCommand);
                  showMsg(ftp.getReplyString() + ": " + siteCommand, verbose);
                  // No port command necessary
                  FileInputStream local = new FileInputStream(fileName);
                  if (ftp.storeFile(mvsFileName, local)) {
                        showMsg("Stored Ok:" + ftp.getReplyString(), true);
                  }
                  else
                        showMsg("Problems storing:" + ftp.getReplyString(), verbose);
                  local.close();
                  return true;
            }
Any way I can figure out before I do the stor if the file already exists or do I have to do an LS or such
And if so, how do I do that and get the data into an form where I can test the existence of the file???
Thanks

None that I can find. I can give you a couple of tips from looking at the docs:

1. use FTPClient not FTP, if you're not already doing that
2. call createFileList on the FTPClient, using your own FTPFileEntryParser with an implementation that closes the stream if the entry is found and returns a FTPFileList of one element, null otherwise

CEHJCommented:
It certainly will need some kind of listing. Look at FTPFileList

Any chance of finding me an example?
The apache javadoc is as terse as anything I have read...

Because it's a superclass of FTPClient with reduced functionality (at a fairly quick glance)
