Problem posting data with HttpsConnection

Question

Hi,
I am currently having problems posting data using a HttpsConnection.
I am setting the setRequestMethod to HttpConnection.POST and then using the openDataOutputStream method.
I will post my code when I get home for reference.
Background to my problem - I am trying to use the declarative security features of J2EE to authenticate a mobile user.
I am firstly firing a HttpsConnection from the mobile device to a protected resource on the app server. I grab the JSessionId from the Set-Cookie http header of the response and post a second request to the j_security_check and provide the refer http header to the protected resource - this simulates exactly what happens on a browser (I used a Http monitor tool to confirm this). However, I need to pass the j_username and j_password as body of the https request. This doesn't seem to work because the server displays my access denied at this point - as if it hadn't received the crednetials
However, just to confirm my technique works I subsituted the post request for a get request to j_security_check and passed the j_username and j_password as request params in the URL. This worked fine and I got a 302 response 'temporily moved' which I then handle by simply making a further request for the original resource - this time it serves back the resource because I am authenticated.
Anyway that sets the scene - so the problem definitely appears to be posting data using an HttpsConnection.
Any help would be greatly appreciated

Hi,
Here is my code relating to the above problem:
httpsConn = (HttpsConnection)Connector.open("https://127.0.0.1:8443/ebank/j_security_check");
            httpsConn.setRequestMethod(HttpConnection.POST);
            httpsConn.setRequestProperty("referer", "https://127.0.0.1:8443/ebank/main/mainMenu.xml");
            httpsConn.setRequestProperty("cookie", cookieValue);
            httpsConn.setRequestProperty("location", url);
            httpsConn.setRequestProperty("User-Agent",
                "Profile/MIDP-1.0, Configuration/CLDC-1.0");
            httpsConn.setRequestProperty("Content-Language",
                "en-gb");
String credentials = "j_username=EB0001&j_password=240589";
            httpsConn.setRequestProperty("Content-Length",""+credentials.length());
            DataOutputStream os = httpsConn.openDataOutputStream();
            os.writeUTF(credentials);
....Thanks,
David
