Hi all,

I'm trying a very simple JSF application in JBOSS AS 6.1. My JSP file looks like this:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core" %>

<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html" %>

<f:view>

    <h:form>

        <center>

...

...

...

<h:commandButton id="refreshLink" value="Refresh">

    <f:ajax render="messages"/>

</h:commandButton>

        </center>

    </h:form>

</f:view>

The system keeps throwing out this error:

/main.jsp(62,4) No tag "ajax" defined in tag library imported with prefix "f"

Please help me. I'm stuck here for a couple of days already. thanks a lot.
