jdbc pg_hba.conf error

Hi,

I'm a newbee to postgreSQL. Does anyone know what this error means.
I'm trying to run the following java program. I have also included the
java program and the pg_hba.conf file.

java db_connect_pgsql.class

Checking if Driver is registered with DriverManager

Registered the driver ok, making DB connection now

Couldn't connect: print out a stack trace and exit.
org.postgresql.util.PSQLException: A connection error has occurred:
org.postgres ql.util.PSQLException:
FATAL: no pg_hba.conf entry for host "127.0.0.1", user

Here is my pg_.conf file

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the PostgreSQL Administrator's Guide, chapter "Client
# Authentication" for a complete description. A short synopsis
# follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access. Records take one of seven forms:
#
# local DATABASE USER METHOD [OPTION]
# host DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# host DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
#
# (The uppercase quantities should be replaced by actual values.)
# The first field is the connection type: "local" is a Unix-domain socket,
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
DATABASE can be "all", "sameuser", "samegroup", a database name (or
# a comma-separated list thereof), or a file name prefixed with "@".
# USER can be "all", an actual user name or a group name prefixed with
# "+" or a list containing either. IP-ADDRESS and IP-MASK specify the
# set of hosts the record matches. CIDR-MASK is an integer between 0
# and 32 (IPv4) or 128 (IPv6) inclusive, that specifies the number of
# significant bits in the mask, so an IPv4 CIDR-MASK of 8 is equivalent
# to an IP-MASK of 255.0.0.0, and an IPv6 CIDR-MASK of 64 is equivalent
# to an IP-MASK of ffff:ffff:ffff:ffff::. METHOD can be "trust", "reject",
# "md5", "crypt", "password", "krb4", "krb5", "ident", or "pam". Note
# that "password" uses clear-text passwords; "md5" is preferred for
# encrypted passwords. OPTION is the ident map or the name of the PAM
# service.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal. If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect, or use
# "pg_ctl reload".

# Put your actual configuration here
# ----------------------------------
#
# CAUTION: The default configuration allows any local user to connect
# using any PostgreSQL user name, including the superuser, over either
# Unix-domain sockets or TCP/IP. If you are on a multiple-user
# machine, the default configuration is probably too liberal for you.
# Change it to use something other than "trust" authentication.
#
# If you want to allow non-local connections, you need to add more
# "host" records. Also, remember TCP/IP connections are only enabled
# if you enable "tcpip_socket" in postgresql.conf.

# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

# IPv4-style local connections:
#host all all 127.0.0.1 255.255.255.255 trust
# IPv6-style local connections:
#host all all ::1
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust

# Using sockets credentials for improved security. Not available everywhere,
# but works on Linux, *BSD (and probably some others)

local all all ident sameuser

Here is my java program that trying to make the connection

import java.sql.*;

System.out.println("Checking if Driver is registered with
DriverManager\n");
//load the driver

}
catch(ClassNotFoundException cnfe)
{
System.err.println(cnfe);
System.out.println("Let's print a stack trace, and exit.");
cnfe.printStackTrace();
System.exit(1);
}
System.out.println("Registered the driver ok, making DB
connection now\n");
Connection dbConn = null;
try
{
dbConn =
DriverManager.getConnection("jdbc:postgresql://localhost/testing123","brakesh","");
}
catch(SQLException sqle)
{
System.out.println("Couldn't connect: print out a stack trace
and exit.");
sqle.printStackTrace();
System.exit(1);
}

if(dbConn != null)
System.out.println("Hooray! We connected to the database!");
else
System.out.println("We should never get here.");
}
}
