How to display XML file that XI sent to my j2ee appl?

Question

Hi,
In my scenario File->XI->J2EE appl.
I got XML page cannot be displayed.
XML document must have a top level element. Error processing resource 'http://localhost:7001/Invoke/DisplayRes'.
I deployed my .ear file on BEA Weblogic application server9.0
I found no error when i tested in SXI_MONI and RWB->Message monitor as well.
This is my servlet code:
public class DisplayRes extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
     doPost(request,response);
     public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
     BufferedReader brin =new BufferedReader(new InputStreamReader(request.getInputStream()));
     String inputLine;
     StringBuffer sBuf = new StringBuffer();
     PrintWriter out = response.getWriter();
     response.setContentType("text/xml");
     while ((inputLine = brin.readLine()) != null)
         sBuf.append(inputLine);       
         //out.setContentType("text/xml");
         //out.println(sBuf.toString());
         out.write(sBuf.toString());
          brin.close();
         out.flush();

Hi
Can anyone tell me how XI sends messages to applications like J2EE. In REceiver comm channel, I think we specify about the target system like J2EE appl.
Aadapter Type: HTTP
               Receiver
Transport Protocol:  HTTP1.0
Message Protocol:    XI payload in HTTP body
Adapter Engine:      Integration Server
Addressing Type:     URL address
Target host:         localhost
Service Number:      7001(Port number of Weblogic appl server--where my J2EE appl is deployed).
Path     :  /Invoke/DisplayRes/
Authentication Type:Use Logon Data for SAP System
Content Type: text/xml
Username:   xiappluser
password:   xx
XML code:   UTF-8
I suppose XI sends msgs to http://localhost:7001/Invoke/DisplayRes/........
in this example if am correct?
Then I have given all tyhe necessary setting but my servlet is not able to display XML msg in browser?
This is my servlet code:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
     PrintWriter out = response.getWriter();
     BufferedReader brin =new BufferedReader(new InputStreamReader(request.getInputStream()));
     String inputLine;
     StringBuffer sBuf = new StringBuffer();
        response.setContentType("text/xml");
     while ((inputLine = brin.readLine()) != null)
         sBuf.append(inputLine);
         out.println("hi");            
            out.println(sBuf.toString());
         brin.close();
         out.flush();
What went wrong?
