[jQuery] tooltip

[jQuery] tooltip


I am jquery beginer,
I write my project using STRUTS 2 and Jquery
I'd like to know how can I add a ToolTip to some existing controller
such as Date Picker, stright forward.
if it looks like the below(jsp page):
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>
<html>
<head>
<sj:head jqueryui="true"/>
<title>Controllers Test</title>
</head>
<body>
        <sj:datepicker >     </sj:datepicker>
....
Second, What is the difference between remote and local
sj:tabbedpanel ?
thanks a lot
