Usually the proxy settings for a Mac can be configured from Network > advanced > Proxies.
The changes made here are automatically applied to Symantec’s Liveupdate.conf file located in Library/Application Support/Symantec/Liveupdate/
Note: These files are not visible by default, use terminal commands to unhide them and proceed. See tech info below for more details.
But the JavaLiveupdate is not equipped to automatically capture and use this setting when you have a username & password configured for proxy. We have to manually configure this in the Liveupdate.conf

Add the below lines in the liveupdate.conf file
