Sun Microsystem has blocked Iran's IPs so you can not download  anything
from sun  sites such as java.sun.com and netBeans.org. The only way is to
use a proxy or buying CDs.

All IP addresses directing to Iran region are filtered by Sun. Use a VPN service.

Actually you can't download  anything from Sun's website because of the sanctions that US imposed over Iran and some other countries. you have to find  your needed files from elsewhere.

Install Ghost Surf 2005 and crack it with this code : ST4000 and this email address : name@.... also you can use 15 days trial version of this software. then set your browser proxy address to : 127.0.0.1 and port to 7212
and download  any thing you need from sun  and other sites.
after you install ghost surf , you should run proxy.exe from istallation rood directory.
and right click the icon in system tray and configure policy in policy center of ghost surf.
if you have problem  with ghost surf email me, I help you
