I'll guess that you have an external type in the model that is not a
Postgres type. I am not sure if that Movies model that you are using
uses prototypes. If not, you can't just use it with a different
database without making changes. If it does use prototypes, then the
Postgres are missing or wrong.

HI Michael;
It is the stuff under "java.lang.NullPointerException" which is
interesting because it will tell us _where_ the problem arose ––
can you re-post your full stack trace please?
cheers.
I'm trying to use the Postgresql with WO.
The application itself is a simple test. Actually, I'm opened the
'WebOBjects Tutorial' - the one, which is building the application
