Java EE (Java Enterprise Edition) General Discussion

Hello all,
I am trying to make a call to a servlet that will basically read the contents of a text file and returns this to a jsp page through an Ajax call.
Problem I am having is the servlet returns nothing.
Here is a snip of my code:

    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        
        File file = new File("C:/logger/Jan31EventLog.txt");
        FileReader filereader = new FileReader(file);
        BufferedReader reader = new BufferedReader(filereader);
        
        String line = null;
        String strLine = "";
        while((line = reader.readLine()) != null)
        {
          strLine = line;
        }
          response.setContentType("text/plain");
          response.setHeader("Cache-Control", "no-cache");
          response.getWriter().write(strLine);
          out.close();
    }

Then in my jsp I make a servlet call through Ajax like so:

function ajaxRead(){

var file = './Logger'; //Logger is the name of my servlet.
//alert(file);
  var xmlObj = null;
  if(window.XMLHttpRequest){
      xmlObj = new XMLHttpRequest();
  } else if(window.ActiveXObject){
      xmlObj = new ActiveXObject("Microsoft.XMLHTTP");
  } else {
      return;
  }

I get no errors so I am not sure if I wrote the servlet properly. If I hard code the file to read with Ajax it works but I need to use the servlet call.
TIA!
