Re: Test Post to Servlet Doesn't Work.

[Boris Erukhimov]

It looks like you are not properly supplying arguments for "POST" method
The right order based on Jason Hunter book example is below:
To use it in your case just put your xml string into Properties object
as a value against "cmd" as a name

 public static final InputStream sendPostMessage(Properties args, URL
destination) 
                throws IOException
  {
    String argString = "";     
    if (args != null) 
        {      
        argString = toEncodedString(args);  
        }

    URLConnection con = destination.openConnection();

    // Prepare for both input and output
    con.setDoInput(true);
    con.setDoOutput(true);

    // Turn off caching
    con.setUseCaches(false);

    // Work around a Netscape bug
    con.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");

    // Write the arguments as post data
    DataOutputStream out = new DataOutputStream(con.getOutputStream());

    out.writeBytes(argString);
    out.flush();
    out.close();

    return (con.getInputStream());
  }
/////////////////sendPostMessage


 private static final String toEncodedString(Properties args)
  {
    StringBuffer buf = new StringBuffer();
    Enumeration names = args.propertyNames();
    while (names.hasMoreElements()) 
        {
        String name = (String) names.nextElement();
        String value = args.getProperty(name);
        buf.append(URLEncoder.encode(name) + "=" + URLEncoder.encode(value));
        if (names.hasMoreElements()) 
                buf.append("&");    
        }
    return buf.toString();
  }
////////////////////toEncodedString

Hope it helps
