Mime type in JSP

[tripti pandey]

i am trying to display a image obtained in byte array through jsp. Following is the code that i am using :
<%
response.setContentType("image/jpeg");
OutputStream o=response.getOutputStream();
byte[] byteImage;
byteImage = request.getParameter("byteImage");
o.write(byteImage);
o.flush();
o.close();
%>

This code works perfectly fine and i am able to see the jpeg image, however problem arises when i putting this jsp in tile-def.xml. Byte dump is being displayed in this case instead of image.
Please help what the problem can be.
