Finally .... The Authentication Issue Resolved for Connecting to PostGreSQL from Java

Hooh! So HAPPY!!! Finally, got it resolved for PostgreSQL 9.2 in Windows Environment

Inside the pg_hba.conf that is inside the folder C:\Program Files\PostGreSQL\9.2\data, navigate to the section titled "# IPv4 ...", and add this:


# IPv4 local connections:
host    all             all             0.0.0.0/0                trust
host    all             all             127.0.0.1/32            trust

For the second row, which is originally there with md5 authentication, make it trust also.

This solution is referenced to: http://www.postgresql.org/docs/9.2/static/auth-methods.html

For more details about any security issue, if your scenario is not for localhost connection. For my case, am trying to connect using localhost.

The following is a sample code used in Java:


import java.sql.*;
import java.util.*;

public class PGSample
{
  public static void main(String[] args)
  {
    Connection connection = null;
    try
    {
      // the postgresql driver string
      Class.forName("org.postgresql.Driver");
 
      // the postgresql url
      String url = "jdbc:postgresql://localhost:5432/TestDB";
   
      // get the postgresql database connection
      connection = DriverManager.getConnection(url,"pguser", "");
   
      // now do whatever you want to do with the connection
      // ...
   
    }
    catch (ClassNotFoundException e)
    {
      e.printStackTrace();
      System.exit(1);
    }
    catch (SQLException e)
    {
      e.printStackTrace();
      System.exit(2);
    }
  }
}

Note: Replace the database TestDB with the name of the DB in your pc or server. Also, replace "pguser" with the user id in your own server.
