title: Tomcat 404 Not Found error
body: <p>My web application runs fine with Eclipse &amp; Tomcat on my desktop PC. When I uploaded the war file to the actual server, I wasn't able to access all the servlets with the following error message. Other JSP and HTML files had no problems.</p>
  
  <pre><code>The requested URL /HelloWorld/TryingServlet was not found on this server.
  
  Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
  </code></pre>
  
  <p>How is this caused and how can I solve this?</p>
