  <p>My typical webapp shared library have the following content</p>
  
  <pre><code>/WEB-INF/
  ---------web.xml
  ---------lib
  ------------ my libraries
  </code></pre>
  
  <p>The content of my web.xml</p>
  
  <pre><code>&lt;?xml version='1.0' encoding='UTF-8'?&gt;
  &lt;web-app 
          xmlns="http://java.sun.com/xml/ns/j2ee" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          version="2.5"&gt;
  
  &lt;/web-app&gt;
  </code></pre>
