Try to use Proxy Server this will allow you to use restricted sites.

Which JAVA related files you are trying to download? or are you trying to download the JAVA files from the sun microsystems site? If you are trying to download the full version of java files which size is over 150 MB then there would be some steps that needs to be follow, but that steps also given on there site.follow that, if you still has problem please let me know.

Is there any firewall installed in your laptop ? becoz firewall is very important program for restricting unauthorised sites for the security reasons. If you need to unrestrict your laptop, try to uninstall the firewall.....
