Servlet and JSP Quick Reference
Including Static or Dynamic Content
  Basic usage: 
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("...");
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("/path/resource");
dispatcher.include(request, response);
out.println("...");
  JSP equivalent is 
jsp:include
, not the JSP 
include
 directive.
