Hola a todos:

Tengo instalada en Linux RedHat 5.0 la versi�n de Postgres 6.3.2-4 con las JDBC
correspondientes.

El problema que tengo es que no s� la manera de acceder al SGBD a trav�s de
Java.

He estado mirando la documentaci�n que acompa�a pero no encuentro nada.

Muchas gracias por adelantado, y hasta otra.


la salida por pantalla es la siguinte:

DriverManager.initialize: jdbc.drivers = null
JDBC DriverManager initialized
registerDriver:
driver[className=postgresql.Driver,context=null,postgresql.Driver@80cb355]
DriverManager.getConnection("jdbc:postgresql:pruebas")
    trying
driver[className=postgresql.Driver,context=null,postgresql.Driver@80cb355]
-- listing properties --
password=
Protocol=postgresql
user=
PGDBNAME=pruebas
java.sql.SQLException: Connection failed: java.net.ConnectException: Connection

	at postgresql.Connection.<init>(Connection.java:190)
	at postgresql.Driver.connect(Driver.java:87)
	at java.sql.DriverManager.getConnection(DriverManager.java:91)
	at java.sql.DriverManager.getConnection(DriverManager.java:134)
	at sql.main(sql.java:41)

El Programa:

import java.io.*;
import java.sql.*;
import java.text.*;
import java.net.*;

public class sql {
  static Connection db;
  static Statement  st;
  
  static public void main(String args[]) throws Exception {
    String url="jdbc:postgresql:pruebas";
/* Tambi�n he probado con:
               "jdbc:postgresql://mi_servidor:5432/pruebas";
^*/

    DriverManager.setLogStream(System.err);

    Class.forName("postgresql.Driver");

    db = DriverManager.getConnection(url,"","");

/* Tambi�n he probado con: 
    db = DriverManager.getConnection(url,"root","");
    db = DriverManager.getConnection(url,"root","mi_contrase�a_unix");
    db = DriverManager.getConnection(url,"postgres","");
*/

    st = db.createStatement();

    st.close();
    db.close();
    
  } //Fin Main
}   //Fin Class
