HTTP POST is killing me, please help ...

Question

Hello,
I am trying to send an XML file to a php script sitting on a server. I want to do this by HTTP POST through a Java Application.
I have the following code developed and haven't an iota why the php script won't pick up the XML file.
If anyone has any idea, suggestions, I will be glad to hear them.
Random random = new Random();
final String CONTENT_BOUNDARY = "------------------------" + random.nextInt();
public String postInvoice(String strFilePathName) {
HttpURLConnection httpsUrlConnection = null;
StringBuffer strBuffer = new StringBuffer();
try {
// Using the File name passed in, setup FileInputStream Object
// to be used to get data to write to URL
File fileToPost = new File(strFilePathName);
//FileInputStream fis1 = new FileInputStream(fileToPost);
// Get the actual filename for setting in the form
String strFileName = fileToPost.getName();
URL urlPostTo = new URL("http://server/some.php");
httpsUrlConnection = (HttpURLConnection)urlPostTo.openConnection();
// Setup RandomAccessFile
RandomAccessFile rafXML = new RandomAccessFile(strFilePathName, "r");
httpsUrlConnection.setRequestProperty("REQUEST_METHOD", "POST");
httpsUrlConnection.setRequestProperty("Accept", "text/xml");
httpsUrlConnection.setDoOutput(true);
httpsUrlConnection.setUseCaches(false);
httpsUrlConnection.setRequestProperty("Content-Type",
"multipart/form-data");
Long longTemp = new Long(rafXML.length());
httpsUrlConnection.setRequestProperty("Content-Length", longTemp.toString());
PrintWriter pwOut = new PrintWriter (httpsUrlConnection.getOutputStream());
// Setup a form field
pwOut.print(CONTENT_BOUNDARY + "\r\n" +
"Content-Disposition: form-data; name=\"Filename\"; filename=\"" +
strFileName + "\"\r\nContent-Type: text/xml\r\n\r\n");
// Send XML contents
StringBuffer strBufferFile = new StringBuffer();
long lngFilePointer = 0;
long lngFileLength = rafXML.length();
while (lngFilePointer < lngFileLength) {
String strTemp = rafXML.readLine();
strBufferFile.append(strTemp);
lngFilePointer = rafXML.getFilePointer();
// Write out File Contents
pwOut.print(strBufferFile.toString());
pwOut.print("\r\n\r\n" + CONTENT_BOUNDARY + "--\r\n");
pwOut.flush();
pwOut.close(); pwOut = null;
// Once everything is written, call the connect method
httpsUrlConnection.connect();
System.out.println("Connected to " + httpsUrlConnection.getURL().getHost());
BufferedReader br = new BufferedReader(new InputStreamReader(httpsUrlConnection.getInputStream()));
String strLine;
while ((strLine = br.readLine()) != null)
strBuffer.append (strLine);
strBuffer.append ("\r\n");
br.close(); br = null;
System.out.println(strBuffer.toString());
catch(FileNotFoundException fnfe) {
System.out.println("FileNotFoundException in HttpPostInvoice : " + fnfe);
catch (Exception e) {
System.out.println("Exception in HttpPostInvoice : " + e);
finally {     
if (httpsUrlConnection != null) {
httpsUrlConnection.disconnect();
return strBuffer.toString();
}

Have that application installed and it makes for interesting reading, not sure I understand it all but anyway ..
Using the code you supplied, this is what is picked up
POST /some.php HTTP/1.1
Content-Length: 4844
User-Agent: Java1.4.0_03
Host: www.host.com
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-type: application/x-www-form-urlencoded
POST http://server/some.php HTTP/1.0
Content-Type: multipart/form-data; boundary=-------------------------1736247667
Accept: text/xml
Connection: keep-alive
Content-Length: 4595
Cache-Control: no-cache
Pragma: no-cache
-------------------------1736247667
Content-Disposition: form-data; name="Filename"; filename="3000001193.xml"
Content-Type: text/xml
<?xml version="1.0"?><Order> ... </Order>
-------------------------1736247667--
Using my original code this is what the app picked up ...
POST /some.php HTTP/1.1
Accept: text/xml
Content-Type: multipart/form-data; boundary=------------------------1514140045
Content-Length: 4557
User-Agent: Java1.4.0_03
Host: www.host.com
Connection: keep-alive
------------------------1514140045
Content-Disposition: form-data; name="Filename"; filename="3000001193.xml"
Content-Type: text/xml
<?xml version="1.0"?><Order> ... <Order>
------------------------1514140045--
I really don't know what to make of it, as far as I can see the request header is ok, with the response being 200. That means the request is ok, but shouldn't the response be 201 indicating that the file was created?
Am going to look at what a POST through a HTML form sends and match up that way ...
