If you want to use the Update Center or access the Internet through the IDE, but your system is behind a firewall or you use a proxy server, you need to configure the IDE with your proxy settings.
To use an HTTP proxy:
To use a SOCKS proxy:
To run the IDE using a SOCKS proxy, you must pass the SOCKS proxy host and proxy port parameters to the JVM software when you start the IDE. On Microsoft Windows machines, use the IDE-HOME/etc/netbeans.conf file to pass the parameters. On UNIX and Linux machines, you can write a wrapper shell script.
On a Microsoft Windows machine:
-J-DsocksProxyHost=SOCKS-SERVER -J-DsocksProxyPort=1080
For SOCKS-SERVER, use the host name of your SOCKS proxy.
On a UNIX or Linux machine:
runide.sh -J-DsocksProxyHost=SOCKS-SERVER -J-DsocksProxyPort=1080
For SOCKS-SERVER, use the host name of your SOCKS proxy.
