AbstractMethodError with PostgreSQL
Hi everyone,
I'm a newbee to OJB, and even my first try led into an exception. When I
tried to play tutorial #1, the first attempt to get some data from the database
fired this exception:
java.lang.AbstractMethodError:

I'm using PostgreSQL database on Suse Linux 8.0 and JDK 1.4, and AFAIK I'm
using the newest JDBC driver for PostgreSQL. So, I have no idea what went wrong,
nor could I find some hints somewhere in the net.
Can anybody help me?
Kind regards,
Christian

In the repository_database.xml file (or where ever you placed the
jdbc-connection-descriptor) is the platform attribute assigned
PostgreSQL or the default Hsqldb?
