Thank you both for your responses. So AJAX is the technique I should refer. Anyone know of any examples / somethings. Also, my colleague asked me this question when I talked to him about a "timed AJAX event". Why cant we simply refresh the jsp page ? Why should we use AJAX ? so, whats the real advantage of using an AJAX timed event to a normal JSP/HTML refresh ? Maya
