  <p>How can I solve this problem?</p>
  
  <p>When I open the <code>localhost:8080/manager/html</code> it shows the following error:</p>
  
  <pre><code>HTTP Status 404 - /manager/html
  
  type Status report
  
  message /manager/html
  
  description The requested resource (/manager/html) is not available.
  Apache Tomcat/7.0.6
