    Default

    Hi friend,
    u can use the response.getwriter,write(String value);in the servlet.
    in the jsp page after response is coming,then u write the code at the ajax code.
    var s=xmlHttp.responseText;
    var tem=s.split("+");
    document.getElementById("name").innerHTML=tem[0];
    and to display the name in the page,u can write the code
    <div id="name"></div>
