Installation problems on Fresh 11.1.0.6 database and Apex 3.1.1

Question

I hope someone can help - at wit's end trying to get Apex up and running. I've looked through the forum over and over and don't see a resolution.
I have installed 11g Enterprise Edition on a Solaris 5.10 64bit Sparc system, created a database, setup and configured dbconsole for enterprise manager.
Database is up, enterprise manager is up and I can connect and browse just fine, but when I went to set up and configure Apex (it was version 3.0 that came with the database) I could only get a blank page trying to go to either the apex or apex_admin pages.
So re-read documentation and couldn't see what I did wrong. So I started a new Apex install, dropping the FLOWS_030000 and FLOWS_FILES users, downloaded apex 311, and did a fresh install.
For the record, I'm trying to use the Embedded PL/SQL Gateway instead of the Oracle HTTP Server.
Here are my steps:
Downloaded apex_3.1.1.zip, loaded it up on server, and unzipped the file
sqlplus "/ as sysdba"
@apexins SYSAUX SYSAUX TEMP /i/
no errors
SQL> @apxchpwd

I ran the following PL/SQL cut and pasted from the install doc to enable network services:
SQL> DECLARE

ACL_ID RAW(16);
BEGIN
-- Look for the ACL currently assigned to '*' and give FLOWS_030100
-- t 2 he "connect" privilege if FLOWS_030100 does not have the privilege yet.
SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS
WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;
-- Before checking the privilege, make sure that the ACL is valid
-- (for example, does not contain stale references to dropped users).
-- If it does, the following exception will be raised:
-- ORA- 3 4 5 6 7 8 9 10 11 12 13 44416: Invalid ACL: Unresolved principal 'FLOWS_030100'

EQUALS_PATH(P.RES, ACL_PATH) = 1;
DBMS_XDBZ.ValidateACL(ACL_ID);

END; 26 27 28 29 30 31 32

I then checked to see if the package was valid:
SQL> SELECT STATUS FROM DBA_REGISTRY
WHERE COMP_ID = 'APEX'; 2
STATUS
VALID
Still, when I go to my browser and enter the following url:
http://dbsu01a.sit.us.wamu.net:7459/apex/apex_admin
all I get is a blank page.
http://dbsu01a.sit.us.wamu.net:7459/apex
returns a "page not found" error.
It must be one of those "is your computer plugged in?" things - any help would be greatly appreciated.

Here was the fix:
My local_listener parameter in the init.ora (spfile) was not set. I ran the following as sys:
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=<hostname>)(PORT=<port>))' scope=both;
Bounced the listener and the database and after about 3 minutes listener status showed the following new endpoint:
Listening Endpoints Summary...
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<host>)(PORT=9969)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<host>)(PORT=7459))(Presentation=HTTP)(Session=RAW)) <-- this is the XDB entry.
After that I was able to log into APEX!
