HttpClient and streaming xml out

Hi all,

We have the need to connect to a server and authenticate using client 
certificates, then stream an xml request out to it. I can do the client 
cert stuff, but can streaming out the xml be done with HttpClient? Our 
current code (without client cert support) is below.

The other method i've tried is just using a plain HttpsUrlConnection, 
but getting it to send the client cert is proving to be tricky. I've 
registered the DefaultSSLSocketFactory, but for some reason it won't 
present my client cert :(

Any thoughts appreciated.

Thanks

Tim

URL urlObj = new URL(url);
HttpURLConnection.setFollowRedirects(true);
HttpURLConnection connection = (HttpURLConnection)urlObj.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(true);
OutputStream os = connection.getOutputStream();
PrintWriter writer = new PrintWriter(os, true);
writer.println(message);
os.close();
InputStream is = connection.getInputStream();
Reader reader = Util.convertInputStreamToReader(is);

Tim,

HttpClient 2.0 supports a reverse model compared to HttpURLConnection.
Instead of providing you with an output stream it can read the request
body directly from an input stream and write it to the socket output
stream for you

http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/PostXML.java?rev=1.10.2.1&only_with_tag=HTTPCLIENT_2_0_BRANCH&view=markup

HttpClient 3.0 can do both with a little help from your side, which
would basically require you to provide a class implementing
RequestEntity interface
