Hello all,
 
I'm trying to get the following simple program to run just to confirm a connection to the database:
 
//PostgresqlClient.java

import java.sql.*;

public class PostgresqlClient{
    public static void main(String[] arguments)
        throws ClassNotFoundException, SQLException{
       
        String driver = "org.postgresql.Driver";
        String url ="localhost";
        String user = "root";
        String pwd = "password";
       
        Class.forName(driver);
       
        Connection con = DriverManager.getConnection(url, user, pwd);
        System.err.println("Connection complete");
       
        con.close();
    }
}

 

I keep getting the folowing errors:

Exception in thread "main" java.lang.ClassNotFoundException: org.postgresql.Driver
        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
        at java.security.AccessController.doPrivileged (Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java :268)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName (Class.java:164)
        at PostgresqlClient.main(PostgresqlClient.java:12)
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

I have tried adding the postgresql.jar file to my CLASSPATH, and have also tried copying the postgresql.jar file to the same directory as the PostgresqlClient.java and PostgresqlClient.class directories. I have also tried running the following from the command line:

java -classpath postgresql.jar PostgresqlClient.class

I am using jdk1.5.0_09 and have tried using nearly all the available postgresql.jar files available.

Any advice would be most appreciated.

Cheers,

Greg Peters....
