Help translating a servlet code to bean

Question

hi all
i'd like to translate a servlet code to bean code
the servlet, called from the <img src""> tag in my web page retrieves an images from a database and, setting the response content-type to "image" returns the image.
i'd like to do it through the common getXxx/setXxx methods of a bean
how to do it?
that's the servlet's code:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, java.io.IOException {
        response.setContentType("text/html");
        ServletOutputStream out = response.getOutputStream();
        try
            Connection connection=(Connection)getServletContext().getAttribute("connection");
            Statement s=connection.createStatement();
            response.setContentType("image/jpeg");           
            ResultSet rs=s.executeQuery("select "+request.getParameter("col")+" from products where id="+request.getParameter("id"));           
            while(rs.next())
                out.write(rs.getBytes(request.getParameter("col")));
        catch(SQLException s)
            response.setContentType("text/html");           
        catch(NullPointerException n)
        out.close();
    } thanx in advance

try this:
<%
response.setContentType("text/html");
try {
Connection connection=(Connection)application.getAttribute"connection");
   Statement s=connection.createStatement();
   response.setContentType("image/jpeg");
   ResultSet rs=s.executeQuery("select "+
              request.getParameter("col")+
             " from products where id="+
              request.getParameter("id"));
   while(rs.next()) {
%>
      <%= rs.getBytes(request.getParameter"col"))) %>
<%
} catch(SQLException s) {
   response.setContentType("text/html");
} catch(NullPointerException n) {
%>
