title: Struts2 taglib needs to include in all files
body: <p>I have a one doubt in struts2. I have a header.jsp page like this:</p>
  
  <pre><code>&lt;%@taglib prefix="s" uri="/struts-tags" %&gt; &lt;html&gt;
      &lt;head&gt;
          &lt;script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.js"&gt;&lt;/script&gt; 
      &lt;/head&gt;
  &lt;body&gt;
  </code></pre>
  
  <p>and my home.jsp page like this:</p>
  
  <pre><code>&lt;%@taglib prefix="s" uri="/struts-tags" %&gt;
  &lt;s:include value="/WEB-INF/doctor/header.jsp" &gt;&lt;/s:include&gt;
      &lt;h1&gt;Hello World!&lt;/h1&gt; 
   &lt;s:include value="/WEB-INF/doctor/footer.jsp" &gt;&lt;/s:include&gt;
  </code></pre>
  
  <p>and footer.jsp is:</p>
  
  <pre><code>&lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>My question is: do I need to include <code>&lt;%@taglib prefix="s" uri="/struts-tags" %&gt;</code> tag only in header.jsp or do I need to include it in both header.jsp and home.jsp?</p>
