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.
