HTMLDB Install Failures 10G

Question

During the install of HTMLDB from the 10G companion CD a raft of ORA-03114: not connected to ORACLE errors occurs. I traced the original error back to the impor_export.sql script. Specifically the create or replace java source name "Utitlity" part. Once this fails the session is disconnected and the rest of the process goes down the tubes.
I tried to re-run these scripts from the command line and then I tried to run just the java source install and it always fails.
I can go through and run the rest of the scripts, but this doesn't seem to help.
I got to:
http://localhost:7778/pls/htmldb/htmldb_admin
and there is nothing there.
In fact http://localhost:7778 only shows the
"welcome to the Oracle HTTP Server" page - there is no links to the DAD configuration or anything else.
I still get errors in the section of the install that comes after htmldb_lang.
I was wondering if anyone knows why the install fails, starting with the create java source "Utility" or why the html_admin pages aren't showing up.
This seems strange to me.

Answer 1

I dropped the two users (flows_010500 and flows_files) and made sure the two entries (db and htmldb) were in both the tnsnames.ora files. I then went and ran 10_comp_home/marvel/ins.sql
When it got to the java source "Utility" part, it once again failed and the remainder of the install failed with the same error:
...Utility
ERROR:
ORA-03114: not connected to ORACLE
create or replace and compile java source named "Utility" as
ERROR at line 1:
ORA-03113: end-of-file on communication channel
...htmldb_custom_auth
ERROR:
ORA-03114: not connected to ORACLE
No errors.
...htmldb_lang
ERROR:
ORA-03114: not connected to ORACLE
Then it gets to the ldpap part of the script, asks for some input and then tries to do these again and fails again (of course).
So I am really at the same point that I was earlier - I can't get past this part of the install successfully.
I did try to connect to the both the db ad htmldb via sqlplus (e.g. username/pass@db and username/pass@htmldb) - and both worked, so I am pretty sure that the tnsnames entries are working fine.
Any thoughts?
