JSP custom taglib lets you create QR codes in your JSP page. Taglib is a
wrapper for Google Charts API. Each tag creates an URL for the image with QR code. For example:
<%@ taglib uri="taglib.tld" prefix="q" %>
<q:QR_URL id="url">
http://www.servletsuite.com
</q:QR_URL>
<img src="<%=url%>" alt="QR code"/>
and you will get some like this:
Tags are:
