Failed to load resource: the server responded with a status of 404 (Not Found)

tl;dr

To fix the error "Failed to load resource: the server responded with a status of 404 (Not Found)", you need to make sure that the file you are trying to access is located in the correct folder. For example, a file should be located in the Jquery folder, which is one folder back from the jsp folder. To do this, you need to update the script tag to include the correct path. The updated script tag should look like this:

<script src="../../Jquery/prettify.js"></script>
