Java WebServer

I am writing a java webserver.  Right now, my server can serve up htm/html files with no problem.  Even .css files inside seem to work (although sometimes when I refresh the page, the css doesnt' take effect).  I have one big quesiton...and a smaller question.

First question (the big one) is - my images are not showing up in the browser.  The way I am printing the requested files (the html files and all the files that are used in the html code) to the browser is by using this code:

  // first my pw var is set like this
  output = new PrintWriter(new BufferedWriter(new OutputStreamWriter(clientSocket.getOutputStream())), true);
  ...
  PrintWriter pw = new PrintWriter(output, true);
  ...
  try {
    /**
     * file input stream for the file requested by the client
     */
    FileInputStream fis = new FileInputStream(fileName);

    for (int i=fis.read(); i != -1; i=fis.read())
      pw.print((char) i);

    pw.println(" ");          // print a blank line for the header
    pw.println(" ");          // print a blank line for the header

    fis.close();
  } catch (IOException e) {
    System.err.println("Could not open or read file " + fileName);
    return;
  }
 
Ok...so, that works fine.  Now, I figured that the reason an image (say a jpg file) isn't being displayed is because it isn't a FileInputStream, but rather a FileImageInputStream.  So, what I did was add another case that if a jpg (i have other files, but i used a jpg file as a test) file was being requested, I'd basically do the same code above, except I'd use a FileImageInputStream.  This didn't work either.  Anyone have any suggestions?!?!

My 2nd question was just a question of curiousity...  When I start my server, it works fine in Netscape when i use http://localhost:8080/ and it also works fine when i enter http://my_ip:8080/  (of course 8080 is the port I'm running the server on).  Now, when I use IE, http://localhost:8080/ will just redirect to the actual files...so in the URL bar, it will just place the local file (i.e. - C:\MyServer\webpage\index.html)...so of course it displays it all correctly because the browser is just reading the straight files...the server isn't doing anything.  When I put in http://my_ip:8080/, it says page not found.  So, I was curious about why IE doesn't work and why Netscape does (not a biggie..just curious...maybe IE just sucks :) )

Thanks!
