Read an XML file and send it to client

Question

Hi,
I'm introducing to servlet development and I'm trying to do some AJAX calls. The client side is implemented, but I have some troubles on the server side. I want to open an XML file and send it to the client. How can I do that? Any special header?
I have implemented this test in PHP, so you can imagine what I would like to do:
if ($type == "xml"){
     $xml = "";
     $file = fopen ("file.xml", "r");
     while (!feof ($file)){
          $xml .= fgets ($file, 4096);
     fclose ($file);
     header ("Content-type: text/xml; charset=ISO-8859-1");
     echo $xml;
}The XML file is:
<?xml version='1.0' encoding='ISO-8859-1'?>
<users>
     <user>
          <name>Pepe</name>
          <age>18</age>
     </user>
     <user>
          <name>María</name>
          <age>21</age>
     </user>
</users>Thanks.

Not very useful:(.
This is my code:
PrintWriter out = null;
        try{
               String type = request.getParameter ("type");
               if (type.equals ("xml")){
                    response.setContentType ("text/xml; charset=ISO-8859-1");
                    out = response.getWriter ();
                    String xml =
                         "<?xml version='1.0' encoding='ISO-8859-1'?>" +
                         "<users>" +
                              "<user>" +
                                   "<name>Pepe</name>" +
                                   "<age>18</age>" +
                              "</user>" +
                              "<user>" +
                                   "<name>María</name>" +
                                   "<age>21</age>" +
                              "</user>" +
                         "</users>";
                    out.println (xml);
        }finally{
            out.close ();
        }This code works. The servlet send back the xml and the client shows the content but, as you can see, i'm not reading the xml file. So my problem is on reading the xml file as a plain text. My code is this:
response.setContentType ("text/xml; charset=ISO-8859-1");
                    out = response.getWriter ();
                    String xml = "";
                    FileReader fr = null;
                    BufferedReader br = null;
                    try{
                         fr = new FileReader (new File ("file.xml"));
                         br = new BufferedReader (fr);
                         String linea;
                         while ((linea = br.readLine ()) != null){
                              xml += linea;
                              //System.out.println (linea);
                         fr.close ();
                    }catch (Exception e){
                         e.printStackTrace ();
                    }But now I get an Exception File not found. The xml file is in the web directory (I'm using net beans 6.8). Where I have to put the file?
Thanks.
