If possible, upgrade to 6.3.2, as it has a more fuller JDBC
implementation, and fewer bugs.

What do you have set in your pg_hba.conf file?

JDBC only works using TCP/IP, but (someone correct me if I'm wrong), the
Perl interface can use Unix domain sockets, so if you have a different
setting in pg_hba.conf, it can cause the fact that perl can connect, but
JDBC not.

Also, if you defined pg_hba.conf to use password or crypt authentication,
ensure you have defined the user in the database, AND a password. A blank
password doesn't work.
