Oracle Database Discussions

I used to use apache/mod pl/sql / html toolkit on 8i and 9i. I've installed 11g on a VM at home to re-learn Oracle after some time away. OK, so they did away with apache, and there's a built in pl/sql gateway. Great, how the heck do you figure out what's not working?

I created a DAD, the DAD seems to exist. I've tried a dozen different URLs, different logon IDs & users, I keep getting "page not found".

Where can you look for logging or troubleshooting info on this process?

Mappings
========
plsql/*

Attributes
==========
default-page=
database-username=ABC
authentication-mode=

so the URL should be http://server/plsql/ ?
I set up a line in listener.ora for port 80

(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = gamer2k3)(PORT = 80))
(Presentation=HTTP)
(Session=RAW)
)

any suggestions?
