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:
QR_URL
Body tag creates QR code for the URL in tag's body. By default (empty body) the current page's URL will be used. Attributes are:
1) width Optional attribute. Describes a width for QR code.
