How to display an XML file as it is in browser that XI sent to my J2EE appl

Question

Hi all!
I have a scenario like File->XI->J2EE appl.
The file is getting picked up from my machine by XI.
Now XI should send that XML file to my J2EE appl.
My servlet receives that XML and displays as it is in browser. But am getting some error like:
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();
what went  wrong? Help me
Thanks

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?
