(I'm new to this list, I hope you will forgive me if this is old info.)
It took me quite a while to figure it out, but I finally got JDBC support
for Postgres working under MacOS X. All you need to do is copy the
postgresql.jar file to the following directory:
/System/Library/Frameworks/JavaVM.framework/Home/lib/ext/postgresql.jar
You don't have to change the classpath, this will do the trick (at least in
my case).
Naturally, the postgresql.jar can be found at:
/usr/local/pgsql/share/java/postgresql.jar
Technical blah-blah:
PostgreSQL 7.1
MacOS X 10.0.3 (Build 4P13)
Java IDE: Project Builder 1.0 (v57)
JDK 1.3
Good luck,
