Unable to open the weblogic admin console problem in launching weblogic console - Page was not found

We had issue on weblogic admin console opening but from back end weblogic server is started perfectly without error but when we open the console in internet explorer, Page was not found.

So after some precheck at OS,we disable the SELINUX and stop firewall(iptables) then the application was opening in internet explorer.

Addind to that you need to have root user access in order to change these.

1)/etc/selinux/config
SELINUX=disabled

And stop firewall

2)/etc/init.d/iptables stop
