connecting from openoffice

I have postgresql 7.2.2 running on linux 2.4.18, jdk 1.4.0x
I can upload an sxw file from a java progam as a blob. I want to
access/edit the file in openoffice
I defined my jdbc7.1-1.3.jar location in tools/options/security/java
I put the jar file by name in AdditionalClasspath in javarc
I put the SystemClasspath=/usr/jdk1.4.0/jre/lib/jdbc7.1-1.3.jar in javarc
I tried to connect using org.postgresql.Driver and I get "this method
not implemented yet. " from OO.
I have attached a file showing some output from postgres that indcates
OO is hitting the database

I have visited the openoffice users list and this one, and dont see an
answer to this problem
I have seen keinlein's excellent howto on mysql also
Some people seem to have this thing working
Any help greatly appreciated
TIA
