Connection refused. Check that the hostname and port are correct

Hi,

I am new to PostgreSQL. I am trying to connect to my PostgreSQL database
installed on Unix. I am getting the following error message,

***************************************************************************
An error occured while establishing the connection.
    Type: org.postgresql.util.PSQLException   Error Code: 0   SQL State:
08004
Message:
    Connection refused. Check that the hostname and port are correct and
that the postmaster is accepting TCP/IP connections.
Exception: java.net.ConnectException: Connection refused: connect
***************************************************************************

I have checked port number, user name, password and they are all
correct. I have also checked that the postmaster is also running.

I have the following settings in my configuration file

Please advice what am I doing wrong
