Installing formspider on oracle database express edition 11.2

Hi formspider team,

I was trying to install formspider on Oracle database express edition and I am getting the following success message in the installion log almost at the end. I am installing it on ubuntu 64 bit:

20:59:29 INFO        - Recompiling FORMSPIDER181
20:59:39 INFO        - Recompile completed

20:59:46 INFO        - formspider is succesfully deployed

However, when I import srdemo and run it I get the following error:

ORA-01435: user does not exist
ORA-06550: line 2, column 3:
PLS-00201: identifier 'SRDEMO.BDF_SCRIPTEXECUTER' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

On further checking the installation log I found the following error:

20:52:40 INFO - /tmp/Formspider3476646990748504945tmp/engine_db/view.sql 20:52:45 INFO - Schema FORMSPIDER181 has 92 invalid objects:

and again :

Please let me know how can I solve this. I would like to test formspider on Oracle xe.

With regards.
