just call your servlet directly via the JavaScript URL, like:

URL = "/servlets/com.myProject.myServlet?field1=" + document.getElementById('field1').value;

then in your servlet, simple setup would be like:

public void doGet(HttpServletRequest req, HttpServletResponse res) {
  try{
    PrintWriter out = res.getWriter();
    String field1 = req.getParameter("field1");
    String result = field1;
// ***** do something with field1
    out.print( result );
    String
  }catch(Exception e){
    logger.debug( e.getMessage() );
    logger.debug( e.getStackTrace().toString() );
  }finally{;}
}

then, back in your JavaScript (code/file):

function updatePage() {
  if (xmlHttp.readyState == 4) {
    var response = xmlHttp.responseText;
    document.getElementById("encryptedPswrd").value = response;
  }
}
