Java Database Connectivity (JDBC)

hi there everyone,

new to JDBC.

not sure, what's wrong with that.
I am using XP, postgreSQL 7.3.3 - the database is fine ( i can create a table via cygwin).

- i have downloaded the pgSQL jdbc driver also set the classpath.

thanks in advanc

===================================


import java.sql.*;


public class Example {


public static void main(String args[])
{
String userName="user1";
String password="whatever";
try
{
String url = "jdbc:postgresql:myDB";
Class.forName("org.postgresql.Driver");
Connection myConnection= DriverManager.getConnection(url,userName,password);


} catch ( java.lang.Exception ex){ ex.printStackTrace();}
}

}

Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
