title: 401 Unauthorized in Tomcat
body: <p>I'm using Tomcat 6.0 as a webserver, and I'm trying to open tomcat manager page, but whenever I enter the username as specified in <strong>tomcat-users.xml</strong> file, I'm getting an error as:</p>
  
  <pre><code>  **401 Unauthorized**
  </code></pre>
  
  <p>Here's my tomcat-users.xml file:</p>
  
  <pre><code>&lt;tomcat-users&gt;
  &lt;role rolename="manager"/&gt;
  &lt;user name="admin" password="" roles="admin,manager" /&gt;
    &lt;/tomcat-users&gt;
  </code></pre>
  
  <p>I restart the tomcat, but it has not helped me. Could someone please tell me what's going on wrong?</p>
