I have found one solution for this problem. In order to explain my solution, I have used some aliases referring to my real parameters. These are:
[ME] = my user name
[MYHOST] = my current workstation hostname (netbios name as well)
[MYHOST.mycompany.com] = my worksation's fully qualified domain name
At the beginning I had the same situation as mentioned above: I was unable to connect to the apex service even after successful installation.
First I have used the tnsping oracle utility:
C:\Users\ME>tnsping MYHOST
This was the answer:
TNS Ping Utility for 32-bit Windows: Version 11.2.0.2.0 - Production
Copyright (c) 1997, 2010, Oracle. All rights reserved.
Used parameter files:
C:\oraclexe\app\oracle\product\11.2.0\server\network\admin\sqlnet.ora
Used HOSTNAME adapter to resolve the alias

(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.106)(PORT=1521)))
TNS-12541: TNS:no listener
You see above a lot of currently active different IP addresses. Only the most important 127.0.0.1 is missing. I work on notebook so the network is "almost always" changing (WLAN, 3G, HSDPA, Ethernet etc.) only the localhost is fixed. And that was the real case of the trouble. (When I was working at the office environment connected to the office network it was also working.)
When I was in this situation I also started to use the lsnrctl oracle utility.
I have seen the following:
LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
STATUS of the LISTENER
------------------------
Alias LISTENER

The command completed successfully
You can see that the service for the apex at 8080 port is missing !!!
I have tried also the normal ping which worked perfectly:
C:\Users\ME>ping MYHOST.mycompany.com
The result was:
MYHOST.mycompany.com [fe80::c27:54a4:1600:86a4%26] ping
response fe80::c27:54a4:1600:86a4%26: time<10 ms
...
You can realize the IPv6 address also exists in my tnsping trial as well.
So I have decided to define MYHOST in my local hosts file directly:
127.0.0.1 localhost MYHOST MYHOST.mycompany.com
Testing now with ping:
C:\Users\ME>ping MYHOST
And the answer:
MYHOST.mycompany.com [127.0.0.1] ping:
response 127.0.0.1: byte=32 time<10 ms. TTL=128
...
At this point I have restarted (stopped and started again) the both running Oracle services (just for sure):
OracleServiceXE
OracleXETNSListener
And look the miracle:
C:\Users\ME>lsnrctl
LSNRCTL for 32-bit Windows: Version 11.2.0.2.0 - Production
LSNRCTL> status

You can see the important line with PORT=8080 and service XE instance.
So I am happy the getting started URL is working again.
