How XI flow from XI to J2EE appl?

Question

Hi all!
I have a secnario file->XI->J2EE appl.
I am using sender file adapter and HTTP Receiver adapter.
I placed XML file in D:\somedir of my machine, it is picking up well by XI, <b>all i want to know is how XI sends this XML file to my J2EE Appl.</b> Because my servlet should display the same XML file in browser. I deployed my J2EE appl on weblogic application server9.0 I am getting the following error:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
XML document must have a top level element. Error processing resource 'http://localhost:7001/Invoke/DisplayRes'.
These are params that i have given in my Receiver HTTP adapter:
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
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.println(sBuf.toString());
          brin.close();
         out.flush();
Where i went wrong please help me,
<i><b>NOTE: I want to know how XI sends XML file to my J2EE appl. I suppose my servlet receives it in request object.</b></i> If so can i use like:
response.setContentType("text/xml");
  String xmlFile = request.getParameter("myXMLFile");
  PrintWriter out = response.getWriter();
  out.write(xmlFile);
  out.flush();
  out.close();
All good answers are rewarded
Thanks a lot!
