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:

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.*;

public class db_connect_pgsql
{
    public static void main(String[] args)
    {
        System.out.println("Checking if Driver is registered with
DriverManager\n");
        //load the driver
        try
        {
         Class.forName("org.postgresql.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.");
    }
