APEX

Hi.
First of all, sorry for my english.
I'm installing APEX (following installation guide step by step) and i have an error in the last step.
When i go to creating a workspace and apex users, i need to go to: http://10.0.3.3:7777/pls/apex/apex_admin
but i get "Service Temporarily Unavailable".
All the steps and pre-requisites have been done without errors.
The Oracle database is 10.0.0.179, standard port, with "libra" as SID.
The http oracle server is in another machine, 10.0.3.3.

My dads.conf:

Alias /i/ "/home/oracle/product/10.2.0/db/Apache/images/"
AddType text/xml xbl
AddType text/x-component htc

<Location /pls/apex>
Order deny,allow
PlsqlDocumentPath docs
AllowOverride None
PlsqlDocumentProcedure wwv_flow_file_mgr.process_download
PlsqlDatabaseConnectString 10.0.0.179:1521:libra
PlsqlNLSLanguage AMERICAN_AMERICA.AL32UTF8
PlsqlAuthenticationMode basic
SetHandler pls_handler
PlsqlDocumentTablename wwv_flow_file_objects$
PlsqlDatabaseUsername APEX_PUBLIC_USER
PlsqlDefaultPage apex
PlsqlDatabasePassword apex
PlsqlRequestValidationFunction wwv_flow_epg_include_modules.authorize
Allow from all
</Location>

I suspect i need to install oracle client in then oracle http server, nothing about that in the installation procedure, but, how can it connect to the database if no oracle client installed?
is it included in http server installation?
another idea?

(I can log in the database as apex_public_user with toad from my PC)
