Hello Jonathan.
As the other replies have pointed out, your code is using/extending
"import java.nio.file.DirectoryStream.Filter;". That is an import for a file
directory filter, and not a servlet filter.
You will want to replace the old import statement with "import
javax.servlet.Filter;" instead.
Some general background on Java Servlets can be found at
https://docs.oracle.com/javaee/7/tutorial/servlets006.htm#BNAGB or
https://www.oracle.com/java/technologies/filters.html , which might be of
interest.
If you type "java tutorial servlet filter" into your favourite search
engine you should find some results that can help you out with writing a
servlet filter.
Hope that helps.
Regards,
James.
