Submitting an OWA Login Form from Java

I’m interested in the way to programmatically log into OWA (Microsoft Outlook Web Access - web-based email client) from Java code and get nothing more than an unread Inbox account - I can read this number from the inbox of the HTML page - but the problem is what happens there is a login.

In fact, if you look at the HTML source on the OWA login page, I see that there is an HTML form element:

<form action="owaauth.dll" method="POST" name="logonForm" autocomplete="off"> 

which gets the button element inside it:

<input type="submit" class="btn" value="Log On" onclick="clkLgn()"> 

From the study of the clkLgn () script, I found that it sends a cookie to the document, so it may not be critical:

function clkLgn()
{
    if(gbid("rdoPrvt").checked)
    {
        var oD=new Date();
        oD.setTime(oD.getTime()+2*7*24*60*60*1000);
        var sA="acc="+(gbid("chkBsc").checked?1:0);
        var sL="lgn="+gbid("username").value;
        document.cookie="logondata="+sA+"&"+sL+";expires="+oD.toUTCString();
    }
}

Basically, how can I submit this form? The following code is my attempt at a problem, I can make an HTTP connection, but I can not show the POST the correct HTTP request.

                URL urlObject = new URL(url);

                HttpURLConnection hConnection = (HttpURLConnection)urlObject.openConnection();
                HttpURLConnection.setFollowRedirects(true);
                hConnection.setDoOutput(true);
                hConnection.setRequestMethod("POST");

                PrintStream ps = new PrintStream(hConnection.getOutputStream());

                ps.print("username="+username+"&password="+password);
                ps.close();


                hConnection.connect();

                if( HttpURLConnection.HTTP_OK == hConnection.getResponseCode() )
                {
                    InputStream is = hConnection.getInputStream();
                    OutputStream os = new FileOutputStream("output.html");
                    int data;
                    while((data=is.read()) != -1)
                    {
                      os.write(data);
                    }
                    is.close();
                    os.close();
                    hConnection.disconnect();
                }
