Custom JSP taglib lets you provide Ajax-based alarm popups. Tag
asynchronously requests your server side (JSP, servlet) and outputs response as a JavaScript
alarm. For example:
<script language="JavaScript" src="cjajax.js"></script>
<%@ taglib uri="taglib.tld" prefix="a" %>
<script language="JavaScript">
<a:AjaxAlert url="/cj/test.jsp"/>
</script>
