Displaying Image Problem

Question

Hello,
I need some advice. I have an existing java application that I am trying to convert into a portlet.
The application is a directory search of people on campus. The only catch is that
I am displaying their photo that is stored on a windows shared drive and I obtained
the path to the image from a database query. So, all of my functions to load and resize
the image are working, it is a matter of integrating everything into a portlet.
This is where I am stumped:
In my doView() method I have this snippet
//imagePath is a path that was found through a database query using a first and Last Name
String imagePath = getImageTag(Last_Name,First_Name);
session.setAttribute("imagePath", imagePath, PortletSession.PORTLET_SCOPE);
res.setContentType("text/html");
Writer writer = res.getWriter();
writer.write("<IMG SRC=" + res.encodeURL(req.getContextPath()+"/WEB-INF/jsp/image.jsp?file=" + imagePath) + ">");I had tried the <img src> line with a static image and it works, but integrating it using a jsp file has been a challenge.
This is what image.jsp looks like:
<%@ page import = "java.io.*" %>
<%
    //get fileName of image from request
    String imgFileName = request.getParameter("file");
    try {
       //get thumbnail of image in byte array format
       byte[] imgData = beans.ImageUtil.getImage(imgFileName) ; 
       response.setContentType("image/jpg");
       out.clear();     
       OutputStream o = response.getOutputStream();
       o.write(imgData);
       o.flush();
       o.close();
    catch (Exception e) {
      e.printStackTrace();
%>The getImage() method works fine in the standalone(non-portlet) application
so I know the code works fine otherwise. It seems like it is a matter of
putting everything together and getting it connected correctly in a
portlet. I am wondering if in image.jsp can't find the method getImage().
Any suggestions?
Perhaps, someone has an idea on bypassing the whole image.jsp idea.
Thanks,
Laura

Looks like you want to access the resource via direct URL. For IMG tag, the browser makes the direct request to the specified image source which is a jsp in your case. But WEB-INF cannot be accessed directly. So instead of "/WEB-INF/jsp/image.jsp" use "image.jsp". i.e image.jsp should not be inside the WEB-INF, put it outside of WEB-INF.
