VBO-1508 and ORA-29902 when trying to configure XML DB

Question

Hello,
after installing a fresh Oracle 9i EE System I would like to start using the XML DB part.
While trying to change the XML DB config using the Oracle Enterprise Manager console I always get an error (see subject).
There was alrady an Apache 2 installed and running on the server. Therfore I checked the httpd.conf in the Oracle admin dir and can find a Port 7783 and Listen 7783 directive.
Maybe the EMC still tries to connect using port 8080? If this is true, how can I change this?
Any suggestions?
Thanks in advance
Stephan

You can create the following package as SYS, and then use the setHTTPPort procedure to change the Port Number...
create or replace view DATABASE_SUMMARY
as
select d.NAME, p.VALUE "SERVICE_NAME", i.HOST_NAME, n.VALUE "DB_CHARACTERSET"
from v$system_parameter p, v$database d, v$instance i, nls_database_parameters n
where p.name = 'service_names'
and n.parameter='NLS_CHARACTERSET';
show errors
grant select on DATABASE_SUMMARY to public
alter session set current_schema = XDB
create or replace package XDB_CONFIGURATION
AUTHID CURRENT_USER
as
procedure setHTTPport (PORT_NUMBER number);
procedure setFTPport (PORT_NUMBER number);
function getDatabaseSummary return xmltype;
procedure folderDatabaseSummary;
end XDB_CONFIGURATION;
show errors
create or replace package body XDB_CONFIGURATION as
FTP_XPATH varchar2(256) := '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port';
