Niko,
I guess all of the above. I have done a little with Ruby on Rails and 
would like to use it, but don'r want to proceed until I solve this 
problem. In my web searching I find documentation of several Ruby 
protocol implementations but some are quite old.

The Java code looks like this:
    String soapAction = args[0];
    String sendmsg    = soapAction+".xml";
    String urlString  = "http://dealer.patagonia.com/za/PXM";
    try {
      URL url = new URL(urlString);
      HttpURLConnection httpConnection =
        (HttpURLConnection) url.openConnection();
      httpConnection.setRequestProperty("SOAPAction", soapAction);
      httpConnection.setDoOutput(true);
      httpConnection.setDoInput(true);
      httpConnection.setRequestMethod("POST");
      httpConnection.setRequestProperty("Content-Type", "text/xml");
      PrintStream httpout = new 
PrintStream(httpConnection.getOutputStream());
      BufferedReader in = new BufferedReader(new 
InputStreamReader(fis));
      /* Get first line of the outgoing message                */
      String line = in.readLine();
      while (line != null) {
        System.out.println(line);
        /* Send the line to the http connection                */
        httpout.print(line);
        line = in.readLine();
      System.out.println("Reading the response stream ...");
      BufferedReader in2 =
        new BufferedReader(
          new InputStreamReader(httpConnection.getInputStream()));
      System.out.println("Response:");
      String line = in2.readLine();
      while (line != null) {
        if (line.length() > 2)
          System.out.println(line);
        line = in2.readLine();

I have fumbled around with Ruby HTTP but am getting nowhere.
I would appreciate any direction you can give.
Peter
