<p>Struts 2 &#8220;a&#8221; tag is used to render a HTML &#8220;<;a>;&#8221; tag. The best practice is always use &#8220;<;s:url>;&#8221; tag to create the URL and embed it into the &#8220;a&#8221; tag.</p>
<p><b>Create Action class:</b><br />
<i><b>DataTagAction.java</b></i></p>
<pre class="highlight">package com.dineshonjava.struts2.action;

<p><b>Create views-</b><br />
