Ajax JSP Tag Library

Urgent: I referred example mentioned in apache site. I am not able to contact Action clas from Jsp for Ajax:autocomplete Can you pleae let me know what is the issue or what i am missing.

autocomplete.jsp <%@ taglib uri="http://ajaxtags.org/tags/ajax" prefix="ajax"%> <link type="text/css" rel="stylesheet" href="/css/ajaxtags.css" /> <link type="text/css" rel="stylesheet" href="/css/displaytag.css" />

<script type="text/javascript" src="/js/prototype.js"></script> <script type="text/javascript" src="/js/scriptaculous/scriptaculous.js"></script> <script type="text/javascript" src="/js/overlibmws/overlibmws.js"></script> <script type="text/javascript" src="/js/ajaxtags.js"></script>

<ajax:autocomplete source="make" target="make" baseUrl="${ctx}/loads/ac.html" className="autocomplete" indicator="indicator" minimumCharacters="2" parameters="service=location" parser="new ResponseXmlToHtmlListParser()" />

you could try firebug in firefox,you can get more details about your application,like the request url and response data and so on
