Error with getOutputStream() when trying to post xml

Question

Hi all,
I'm attempting to use the URLConnection class to open up a connection to peform an http post with some xml. When opening the data output stream, I am receiving an internal server error (500) on my Weblogic 6.1 server. The error is occuring at the line:
DataOutputStream dataOut = new DataOutputStream(urlConn.getOutputStream());
My entire code is as follows:
<%@ page language="java" %>
<%@ page import="java.util.*"%>
<%@ page import="java.io.*"%>
<%@ page import="java.net.*"%>
<%
String xml_body = "<my xml string here>"
String sourceUrl = "https://wwwcie.ups.com/ups.app/xml/Rate";
URL url = new URL(sourceUrl);
URLConnection urlConn = url.openConnection();
// prepare input and output, disable caching, set properties
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
urlConn.setUseCaches(false);
urlConn.setRequestProperty( "Content-Type", "application/x-www-form-urlencoded");
urlConn.setRequestProperty("Content-Length", " " + xml_body.length());
((HttpURLConnection)urlConn).setRequestMethod("POST");
// Post output
DataOutputStream dataOut = new DataOutputStream(urlConn.getOutputStream());
dataOut.writeBytes(xml_body);
dataOut.flush();
dataOut.close();
//DataInputStream dataIn = new DataInputStream(urlConn.getInputStream());
// do input processing here
%>
Am I implementing this class properly? I see a NumberFormatException being thrown...but at not sure why this is occuring for my data output stream. The error in my log is as follows:
####<Jul 29, 2003 1:53:45 PM MDT> <Error> <HTTP> <SFNTCPSWEB> <PIA> <ExecuteThread: '44' for queue: 'default'> <> <> <101020> <[WebAppServletContext(7077998,PORTAL,/PORTAL)] Servlet failed with Exception>

Hi,
Assuming that you are making a valid connection to the https://
(What jre are you using, 1.4+ ?)
A DataInputStream is for reading primitive Java types, yea? Which is why you get a parse integer error, no doubt from some URLencoded data. Try using a BufferedInputStream instead. If it is not a tremendous amount of data, append it in a string buffer then use a java.net.URLdecoder to get the true data :-)
Hope this helps,
