How can I read the URL entered in a browser's address bar?

Question

My Java application used in blocking certain websites, when the application is running the websites that mentioned in it must be blocked. So, when anyone trying to reach a certain website from any browser I have to read the URL he trying to reach and compare it with the forbidden websites that stored in my application.

This is my problem, I can't connect the browsers that are in the system with my application. kind regards and sorry for that much talk :)

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;


HttpServletRequest currentRequest = (HttpServletRequest) ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
