Custom error pages

If you want to display a custom HTML error page for a given status code, you add a file to an /error folder. Error pages can either be static HTML (i.e. added under any of the static resource folders) or built using templates. The name of the file should be the exact status code or a series mask.

For example, to map 404 to a static HTML file, your folder structure would look like this

src/
 +- main/
     +- java/
     |   + 
     +- resources/
         +- public/
             +- error/
             |   +- 404.html
             +-
