Error 404 after deploying Navigator to Apache Tomcat

After deploying Navigator to Apache Tomcat, a 404 error sometimes appears in the browser console when trying to access the Navigator URL using ip:port/navigator.

Solution

Perform the following steps to resolve this issue:

  1. Stop Apache Tomcat.
  2. Go to the Apache Tomcat configuration folder and open the web.xml file.
  3. Look for the <welcome-file-list> tag. If it is present, add the following line under this tag:  
    <welcome-file>index.html</welcome-file>
    If it is not present, then add the following to the end of the web.xml file before the </web-app> tag. 
    <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    </welcome-file-list>
  4. Save the web.xml file.
  5. Start Apache Tomcat.
  6. Try accessing Navigator by using the URL, ip:port/navigator.
