XML Interface errors

Question

Help. I can't get the XML interface for authentication to work from a Java program. Yes I know there's another interface for use with Java but I can NOT use it due to some class conflicts. I am having the same problems I've seen reported before in this and other forums. But one one seems to reply with a solution. I'm willing to admit that it is probably something silly but I don't seem to be able to figure out what's wrong.
I've tried sending two different XML strings to initialize the authentication request. For both I get an HTTP response code of
500 on the client. In the webserver log one gives me the "No request handler for service" error message the other the "Premature end of file" error.
What am I doing wrong?
thanks,

HttpURLConnection connection = (HttpURLConnection) urlTest.openConnection();

connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "text/xml");
connection.setRequestProperty("Content-Length", String.valueOf(xmltext.length()));
connection.setRequestProperty("Content-Type", "text/xml; charset=\"UTF-8\"");
connection.connect();
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(),
"UTF8");
// Actually writing to local buffer - not posted to server yet
out.write(xmltext);
out.flush();
// Actual post to server happens on this call
InputStream is = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);

Answer 1

Thought I'd respond to my own post so no one else has to waste time on this.
The problem was that I had a space between the Request and CDATA tags. Removing the space <Request>[CDATA fixed the premature end of file problem. I also removed other spaces between tags just in case.
Below is an example of XML I used to get a valid response for the authentication service.
