Regarding this, I have checked the listener status is given below:
-bash-3.1$ lsnrctl status

Listening Endpoints Summary...
Service "PLSExtProc" has 1 instance(s).
Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
in status, there should be
Service "XE" has 1 instance(s).
Instance "XE", status READY, has 1 handler(s) for this service...
but these above lines are missing,
so please help me by solving the problem...
Just check what is your hostname ?
From your listener status " ftress7 " , this should be your hostname. so your link to apex would be like https://<hostname>:8080/apex
Check your /etc/hosts file , whether you have the static ip address for your hostname. if not, it should be there.
Then one more check is that your listener should listen to your database. but in your case its not.
So login to the database using " sqlplus / as sysdba "
and then enter " alter system register "
Check and let us know the status
