Problem in showing binary data from database

Question

Hi,
I store some image files in my Oracle database and I want to show them in JSP pages. I constructed a jsp page which returns the image, foto.jsp looks like this:
<jsp:useBean id="photo" class="BizDel.Foto" scope="session" />
<%
int iNumPhoto;
Connection conn=null;
try{
DriverManager.registerDriver(new OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@server:1521:orcl", "username", "password");
conn.setAutoCommit (false);
byte[] imgData=Foto.getPhoto(conn);
response.setContentType("image/gif");
ServletOutputStream o=response.getOutputStream();
o.write(imgData);
o.flush();
o.close();
catch(Exception e)
e.printStackTrace();
throw e;
finally
conn.close();
%>
Foto.getPhoto() returns the image file as a binary array.
In the jsp page that I want to display the image, I wrote
<img src=foto.jsp/>
I see that the image processed, but nothing is displayed in the page. When I wrote the foto.jsp directly in the address bar, the image is retrieved properly and the page tries to process it as a file(tries to find a plugin for displaying the image file, that I dont want to.).
Can anyone help?

Andi,
Thanks for your suggestion.
I tried your way. Here is the servlet code:
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
int iNumPhoto;
Connection conn=null;
if(request.getParameter("imgID")!=null){
iNumPhoto=Integer.parseInt(request.getParameter("imgID"));
try{
DriverManager.registerDriver(new OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@server:1521:orcl", "username", "password");
conn.setAutoCommit (false);
          //retrieves the photo from database, works well...
byte[] imgData=Foto.getPhoto(conn);
response.setContentType("image/gif");
OutputStream o=response.getOutputStream();
o.write(imgData);
o.flush();
o.close();
catch(Exception e)
e.printStackTrace();
throw e;
finally
try{conn.close();}catch(Exception e){}
Again, there is no exception but the page does not show the image. When I directly write the servlet in the address bar, this time nothing happens, I cannot see the image.
Any suggestions...?
