I don't see ERX anything in that entire stack. Are you using Wonder? It does not look like it. I would strongly suggest you do. I honestly can't imagine trying to develop a WO app without it. I installed the latest postgres with WO 5.4.3 this weekend. Thanks to Wonder's prototypes and Postgresql plugin, it was painless and simple! Thank you team Wonder!!! (^_~)d
If his model is not using prototypes (or is not using the Wonder prototypes), that won't help.

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
