You can use Java code in JSPs so you can read any file the same way you would do it in your normal Java programs. The important thing to realize is that JSPs run on the server and so any paths you specify are relative to the server.

1.) Please use code tags when posting code.
2.) What was the error message that you got.
3.) Your HTML page does not have a body?

You need to use the servlet context to get to that file's path, something like

 URL url =config.getServletContext().getResource("mm.html");

BufferedReader br =new BufferedReader(new InputStreamReader(url.openStream()));

" 1. The message you have entered is too short. Please lengthen your message to at least 20 characters."

Make sure your post exceeds 20 characters and is not inside quote tags. Just use the Post reply button at the bottom which doesn't include the usually unnecessary quote.
