The postgreSQL .jar file must go in common/lib _not_ share/lib. Two other
things:

1) have you enabled tcpip on the postmaster by seting

tcpip_socket = true

in /var/lib/pgsql/data/postgresql.conf

2) have you edited /var/lib/pgsql/data/pg_hba.conf to un-comment the line

# host all all 127.0.0.1 255.255.255.255 trust

because if you haven't done both of these, you won't be able to connect
from Java.

And before anybody jumps in, I'll just point out that the "host" line is
far too permissive to be used in production but if you're just starting
out experimenting with PostgreSQL and Java, it's one less thing to have to
worry about for now.
