Thread: Passing session ID over HttpURLConnection

Hi,

I have a jsp page and a class. I am creating a new object from the class in the jsp and in the class I have HttpURLConnection, the url given is authorization required it mean it checks for the session.

What I want to do is I want to pass the session in jsp to HttpURLConnection.

Here is my jsp:

ExportToPDF pdf = new ExportToPDF();
pdf.setUrlString("http://www.javaprogrammingforums.com");
pdf.createPDF(request, response, session);

and here is my method in my class:

public void createPDF(HttpServletRequest request, HttpServletResponse response, HttpSession session) throws IOException, ParserConfigurationException, 
			SAXException, DocumentException {
 
		String sessionId = session.getId();
		URL url	= new URL(this.getUrlString());
 
		HttpURLConnection urlConn = null;
		urlConn = (HttpURLConnection) url.openConnection();
 
		urlConn.setRequestMethod("POST");
                HttpURLConnection.setFollowRedirects(true);
                urlConn.setDoOutput(true);
                urlConn.setDoInput(true);
                urlConn.setUseCaches(false);
                urlConn.setAllowUserInteraction(false);
                urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                urlConn.setRequestProperty("Content-Language", "en-US");
                urlConn.setRequestProperty("Cookie", sessionId);
 
		InputStream byteStream 	= urlConn.getInputStream();
 
		OutputStream os = response.getOutputStream();

Can you help me what am I missing here ?
Thank you.
