Not getting header of HTTP Response in Netweaver 7.1

Question

Hello,
I m trying to use HttpURLConnection to authenticate with some site. I m able to send the request and recieve the response from the server. But I m not getting the header of the response. When I do it as simple java application everything works fine but when I deploy it as EJB on Netweaver 7.1, I m not getting the header information from the response.
my code:
URL  url = new URL(Some URL);
HttpURLConnection  conn = (HttpURLConnection )url.openConnection();
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestMethod("GET");
conn.setInstanceFollowRedirects(true);
conn.setUseCaches(false);
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(some data);
sessionID = getSessionID(conn);
wr.flush();
          // Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String resultXML = "";
String line;
while ((line = rd.readLine()) != null) {
      resultXML += line;
Above I m getting the reponse from the site. But the header is not present in that response.
So when I use  conn.getHeaderFields() I get emply Map.

Hi Naveen,
  Please follow steps for deploying the application.
1)open SAPMMC.
2)You will see three green folder name and last two will contain some one digit number in last.
3)Please note down these numbers say 1 and 2 (instance number).
4)Open developer studio.
5)now navigate to windows->preferences->SAP AS JAVA
6)If any thing is listed under SAP System Instances please remove by clicking on Remove SAP System.
7)Now under SAP Instance Identity, enter 1(see step 3)  for Instance number and IP address of your machine/ where SAPMMC is installed.
8)Click on Register SAP Instance and press OK.
I hope It will help you.
Kind regards
