for a time ,

you just remove/comment the entire <servlet> tag and <servlet-mapping> tag in your web.xml & then try to run & say what you get .

& don't forget to restart server after any changes you are making in web.xml.

Hi Dominic !

Try this http://localhost:8080/Beer-v1/

Is it giving any list containing name of html files ?

If your answer is yes then
you must have misspelled your file name or something like that
you must have not provided the classes folder inside WEB-INF which will contain your servlet according to your web.xml.

No, it's because the compiler calls the method with the most specific subclass, as the link already provided states.

That's correct .but tell me whether i am right or not
as per what i think is that most superclass means most specialized class and specialized means most specific class

You are right if yo'll use most subclass instead of most superclass.........
