I am looking for a plugin or software to control the browser for following functionality.

When user submitted request(URL) from browser that request hitting my application(it is running on local PC) and it is comparing with predefined list of URLs , if that requested URL is available in predefined list it will block response other wise it will give normal response

I am looking for a method that does not use the hosts file, or a proxy.

sounds like the wrong tool for the job, by a longshot! because java normally only works inside or rather as a virtual machine and doesn't see outside that. and normally one uses a (web) proxy server to block sites. It might be possible though. But how to do it in java is a programming question, for stackoverflow. should be migrated there – barlop Oct 13 '11 at 11:54
I don't even think the wrong tool can even be used in a case like this. The user can simply uninstall Java which makes your program not run. – Ramhound Oct 13 '11 at 12:25
@ramhound; @barlop: I think he wants to block a website which has a (malicious, lascivious?) java program?? – horatio Oct 13 '11 at 15:50
@horatio ah you're probably right – barlop Oct 15 '11 at 9:43

A much better solution would be to block said website on an upstream network device. This would be a router, firewall, or similar. What you are asking doesn't really make any sense.

There are some pre-existing softwares to handle this. You can use that, if you are comfortable.

Rather than re-inventing the wheel.
