at last count there are 16 different supported drivers for Postgres
http://jdbc.postgresql.org/download.html#current
which driver are you implementing?
BTW here the url should be
jdbc:postgresql://host:port/database
contents of %POSTGRES_HOME%/data/postgresql.conf:
listen_addresses = 'localhost' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost', '*' = all
# (change requires restart)
port = 5432
assuming the host and port are identical the URL should be..
jdbc:postgresql://localhost:5432/databaseask your DBA what the name of the DB
is..
