I am using postgresql-8.1-407.jdbc3.jar and the postgis jar-file from http://postgis.refractions.net/download/postgis.jar. I tried the advice from the postgis-users Archive dated November 27th, 2006 and renamed the postgresql-8.1-407.jdbc3.jar to pgsql.jar but this did not solve the problem.

This sounds like a class loader problem to me. Is it possible that
there is another postgresql-jdbc jar deployed for the same virtual
machine (maybe in the JRE ext/ directory, or in another webapp)?

It's also possible that the jdbc3.jar is found twice by different
branches of the classloader tree.

Classloader problems can be weird to debug, but I will try my best to
assist you.

Regards,
Markus
