jdbc connection refused, please help

Hi all,
I'm definitely a postgreSQL newbie. In trying to hook up postgreSQL to a
JSP engine (Java Web Server) using the postgreSQL jdbc driver, I get the
following error:

Message: Something unusual has occured to cause the driver to fail. Please
report this exception: java.security.AccessControlException: access denied
(java.net.SocketPermission 127.0.0.1:5432 connect,resolve) Error code: 0

Anyone have any ideas how I can work around it? I'm not sure why
connect,resolve isn't allowed...but here's the relevant line from my
pg_hba.conf:

# TYPE DATABASE IP_ADDRESS MASK USERAUTH MAP

host all 127.0.0.1 255.255.255.128 trust
