Create a folder in the src/main/resources folder of your application project called static-html
Copy your file into the directory – let’s assume it’s called foo.html
Rebuild the application to bundle the file into a jar file
Start Cougar
In a browser, go to http://<your-host-name>:<port-number>/static-html/foo.html

To customize the location of the static HTML directory:

Create the ‘info’ directory under some appropriate JAR’s src/main/resources dir
Add the following properties to your app

cougar.htmlHandler.contextPath=/info
cougar.htmlHandler.regex=/info/.*

I think the regex controls what resources the client of the embedded web server is allowed to access directly.
