问题
I am trying to use JQuery in my JSF page embedded with RF3.3.1.. Here is my code snippet:-
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>
<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JQuery Effects</title>
<script type="text/javascript" ></script>
<a4j:loadScript src="resource://jquery.js"/>
<script>
var $j = jQuery.noConflict();
$j(document).ready(function()
{
$j("#formId\\:showLinkId").click(function()
{
alert("Hide Done");
});
});
</script>
</head>
<body>
<f:view>
<h:form id="formId">
<rich:panel header="Jquery" style="position: relative; width: 350px;">
<h:commandButton id="showLinkId" value="Click Here"/>
<h:outputLabel id="success" value="DONE" ></h:outputLabel>
</rich:panel>
</h:form>
</f:view>
</body>
</html>
However when I get the following exception on server when this page is loaded:-
15:16:27,062 ERROR [STDERR] org.apache.jasper.JasperException: An exception occurred processing JSP page /hssViewStore/Test.jsp
10: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
11: <title>JQuery Effects</title>
12: <script type="text/javascript" ></script>
13: <a4j:loadScript src="resource://jquery.js"/>
14: <script>
15: var $j = jQuery.noConflict();
16: $j(document).ready(function()

NOT ONLY this my JQuery itself is not running...I was told to include the .js file using .When I did that it threw the exception... I included the jQuery-1.7.1.js file in my web-inf.
This is what i have done to include the file:-
I copied the script code from jQuery website and created a new js file in Eclipse IDE. Copied the entire script code in new js file and names it as jQuery-1.7.1.js.This is the file I am using for Jquery. Is there anything wrong here?
Except jQuery-1.7.1.js I have no other js file related to JQuery.
Please guide me...

Even though this is an older question, I thought I'd post my findings for those of us who happened upon this looking for an answer.
It appears that the <a4j:loadScript> element needs to be inside <f:view>.
See here for a similar issue.

if nothing else works you can use richfaces built in support for jquery without including the script
